George Mason and MetroStar launch partnership to fuel federal tech talent and innovation Katarina Benson Fri, 12/12/2025 - 11:02

More than two decades ago, three George Mason Ģ��AV students launched a company from their dorm room with a belief that technology would drive change in the federal government.

Today, that company—MetroStar, a venture-backed leader in AI enabled services—has come full circle. The company is proud to announce a multi-year strategic partnership with George Mason, solidifying a shared mission to empower the next generation of tech leaders and public servants.

Through the agreement, MetroStar will support students and programming across George Mason. It will become a Costello Corporate Partner in the Donald G. Costello College of Business and an Industry Partner in the College of Engineering and Computing (CEC).

Through these partnerships, MetroStar will launch a scholarship for undergraduate and graduate students with preference for those minoring in government contracting or management information systems, and a Clearance Ready Scholarship for students interested in obtaining a national security clearance.

“MetroStar’s investment in the Costello Corporate Partners program aligns closely with our strategic priorities, particularly in fostering innovative business collaboration and advancing career readiness,” said Ajay Vinzé, interim provost and Costello College of Business dean. “Their support will expand access to education in government contracting for our students and strengthen the academic offerings of the Greg and Camille Baroni Center for Government Contracting, the first university-based center in the nation focused on the business, policy, and regulatory dimensions of this vital sector.”

MetroStar will also support academic initiatives through the Dean’s Excellence Funds in CEC and Costello, in furtherance of strategic academic initiatives. “This gift from MetroStar, which will support the education and training of our students who are interested in serving our nation as federal employees or as employees of our government contractors,” said CEC Dean Ken Ball. “The partnership will also enhance our clearance ready programs by developing additional experiential learning opportunities, including internships and applied research projects involving classified technologies that protect our nation.”

MetroStar’s CEO and co-founder Ali Reza Manouchehri, BA Philosophy '99.

The philanthropic commitment deepens MetroStar’s long-standing relationship with its co-founders’ alma mater while advancing workforce readiness and innovation aligned to national priorities.

MetroStar’s CEO and co-founder Ali Reza Manouchehri, who earned a BA in philosophy from George Mason in 1999, is the 2025 Winter Commencement Speaker, a privilege that shows his enduring connection to the university and his passion for inspiring the next generation of innovators.

“This is more than a corporate partnership. It’s a personal return,” said Manouchehri. “George Mason is where we built the foundation for MetroStar. We’re investing in students who will one day shape the digital future of government just like we dreamed about doing back then.”

Manouchehri started MetroStar with fellow Patriots Robert Santos, BA International Relations ’99, who became the company’s president, and Pirooz Javan, BS Systems Engineering ’02, who served as its chief operating officer from 1999 to 2006.

A Vision for the Future Federal Workforce

The three-year partnership, running through 2028, creates a new model of agile collaboration between academia and the public sector, bridging the fast-paced world of government innovation with the grounded mission of education. It reflects the growing need under the new federal administration to build talent pipelines that are not only technically skilled but clearance ready and public service minded.

Earlier this year, George Mason released its plan for advancing a responsible approach to harnessing artificial intelligence (AI) and driving societal impact. Through AI²Nexus, the university is building a nexus of collaboration and resources on campus, in partnerships like the one with MetroStar, and across the state.

As federal agencies embrace AI, digital transformation, and faster acquisition models, companies like MetroStar are reinforcing the importance of the human side of innovation, ensuring that the workforce of tomorrow is built on a foundation of collaboration, education, and civic commitment.

From College Campus to National Service

The partnership extends into the university’s forward-leaning spaces, places where creativity, entrepreneurship, and service intersect.

MetroStar’s partnership will fuel the Mason Innovation Exchange (MIX), a hands-on incubator for student-driven ideas, and power events like PatriotHacks, the university’s high-energy hackathon that challenges students to solve real-world problems with code and courage.

“Our partnership isn’t about one-off contributions but investing in people and the future of civil servants who will protect and guide the nation,” said Manouchehri. “We’re creating deliberate pathways from campus to cleared service, from idea to implementation, and from classroom projects to real-world impact.”

George Mason and UVA researchers look into the future of hydrogen sensors

Katarina Benson — Thu, 11 Dec 2025 14:50:07 +0000

George Mason and UVA researchers look into the future of hydrogen sensors Katarina Benson Thu, 12/11/2025 - 09:50

As the use of underwater, aerial, and unmanned ground vehicles continues to grow, it is critical that the fuel cells necessary to power these systems operate safely, while providing durable and optimal performance. High-performance hydrogen sensors, which monitor leakage, energy efficiency, and durability under a wide range of operating conditions, are key to this function.

Currently, palladium-based electrochemical hydrogen sensors are primarily used; however, they often exhibit low sensitivity, a slow response rate, and mechanical instability. Hybrid materials are emerging as a better solution, but questions remain regarding their efficacy.

That was the crux of the request for 4-VA funding from George Mason Ģ��AV’s Pilgyu Kang and Stephen Baek of the Ģ��AV of Virginia. Kang saw an opportunity to explore this new avenue in hydrogen sensing, but also saw the need to integrate Baek’s expertise in scientific machine learning to identify optimal design parameters—including nanoparticle size, distribution, surface coverage, and porosity—that govern the sensor’s sensitivity, response time, and long-term stability. 4-VA funding is designed to support these kinds of collaborations.

Kang, an assistant professor in the Department of Mechanical Engineering, is pleased with the results. After months of wide-ranging study, the team can now predict with the help of machine learning how changes in material design affect sensor performance. This helps the team quickly test many design possibilities and find the best combinations—something that would take much longer with experiments alone.

“Our research team has made exciting progress in developing advanced materials for next-generation gas sensors,” said Kang, who has a lab on George Mason’s Science and Technology Campus. “We’ve created and tested nanocomposites made from laser-induced graphene and metal nanoparticles to improve how sensors respond to light and detect gases like hydrogen and methane. The materials we’ve developed show promising photo response behavior, which is a key step toward building compact, highly sensitive sensors for environmental and industrial use.”

Since the initial proposal, Kang has added outside collaborators NASA Goddard Space Flight Center (GSFC) and N5 Sensors, both providing important platforms to explore potential commercialization paths.

NASA GSFC researchers Peter Snapp and Mahmooda Sultana collaborated with the team on the development of a methane gas sensor. They provided expertise in space-relevant sensing technologies and contributed guidance on performance requirements, testing protocols, and potential integration pathways for aerospace applications.

“This collaboration strengthens the translational potential of the 4-VA-supported laser-induced graphene nanocomposite sensing platform for real-world and extreme environment use cases,” said Kang.

N5 Sensors offered industry insight into the commercialization potential of the laser-induced graphene-based sensor platform. Their involvement included feedback on sensor integration strategies, performance metrics relevant to the market, and potential pathways for transitioning the research from lab-scale prototypes to scalable, deployable systems.

Peter Cho of the Department of Mechanical Engineering also worked with the team, volunteering his time to evaluate the hydrogen sensing performance of the developed materials and providing advice on sensors relevant to fuel cell applications.

Kang said the 4-VA funding also helped create valuable hands-on research opportunities for undergraduates. He credits four mechanical engineering majors who made significant contributions to the project:

Philip Acatrinei shared key material and device integration techniques—particularly in the use of laser-induced graphene and nanocomposite fabrication for advanced sensor platforms.
Graham Harper studied laser-induced graphene and nanocomposite materials for optoelectronic sensing applications.
Noemi Lily Umanzor helped to validate the broader versatility and cross-disciplinary potential of the materials and manufacturing approaches developed in the project.
Diego Enrique Colmenarez performed experimental tasks involving the laser manufacturing and characterization of graphene-based nanocomposites. For his work, Colmenarez received the “Outstanding Project Award” at the College of Engineering and Computing Undergraduate Research Celebration. He also presented on the subject at the American Society of Mechanical Engineers Undergraduate Research Symposium on Dynamics, Vibration and Acoustics.

The team has already had two published papers on the project in the Journal of Materials Chemistry C and Advanced Science, but Kang sees the 4-VA project as a launching pad for much more.

“The funding provided the essential support needed to launch a high-risk, high-reward interdisciplinary research project that might not have been possible through traditional funding channels alone,” he said. “Beyond advancing the technical goals, the support from 4-VA has helped position our team for larger external funding, fostered long-term partnerships, and demonstrated how collaborative, cross-institutional work can drive real innovation.”

Concrete possibilities create 4-VA match Katarina Benson Mon, 11/17/2025 - 12:32

In the construction trades, engineers and builders are constantly pursuing concrete mixes that provide greater durability and strength. Moreover, concrete adaptations that are biodegradable and nontoxic with reduced greenhouse gas emissions attract even more attention. The potential cherry on top of both would be if the adaptation could result in lower production costs.

It was this proposition that brought Xijin “Emma” Zhang, an assistant professor in George Mason Ģ��AV’s Sid and Reva Dewberry Department of Civil, Environmental and Infrastructure Engineering together with Bryan Berger, a professor in Ģ��AV of Virginia’s Chemical Engineering Department.

When Zhang, who specializes in fungi-mediated self-healing concrete, found Berger via the National Science Foundation’s search tool, she immediately recognized that Berger’s extensive experience in producing various biosurfactants from fungi would make him the perfect partner for her 4-VA research team.

Zhang’s goal was to test the effect that Superabsorbent Polymers (SAP) would have on concrete. SAPs are hydrophilic polymers used to reduce shrinkage and improve durability. Berger was up for the challenge.

To turn the idea into reality, Zhang developed a proposal for 4-VA funding titled “Multifunctional Fungi-Based Biosurfactants for Durable Concrete Structures.” The plan was to do a barrage of experiments injecting a type of biosurfactants known as HFBI, derived from engineered yeast strain, to demonstrate the feasibility of it as a sustainable alternative to conventional air-entraining agents. This research would demand careful study and analysis with particular attention to air content and workability.

Once the proposal was approved, Zhang and Berger assembled a team of students to help deliver the project:

Graduate research assistant Junyi Wang from George Mason was responsible for experiment design, mortar testing (workability, air content, compressive strength), data analysis, and draft manuscript preparation.

PhD in chemical engineering Mack A. Kinkeade from Berger’s lab at UVA supported biosurfactant extraction and purification.

PhD student Lixin Wang, also from George Mason, assisted with sample testing.

Two civil engineering undergraduates, Phillip Christovaladi Vasilakopoulos and Rafferty Houghton, volunteered their time on the project, gaining critical research experience. Both graduated in May.

“This 4-VA project provided valuable research opportunities for students at multiple levels. Their involvement not only enriched their academic experiences but also helped build a strong pipeline of future researchers,” said Zhang.

Following a year of lab work, the team did prove their hypothesis—HFBI is a sustainable alternative to established air-entraining agents in concrete.

Zhang was then able to share their results with a variety of interested organizations including the American Concrete Institute, Brookhaven National Lab, and the Federal Turner-Fairbank Highway Research Center.

“These presentations at conferences and national labs helped us connect with industry partners and broadened the impact of our work,” she said.

Zhang sees the 4-VA experience as a success on many levels, including relationship building.

“The 4-VA@Mason funding was instrumental in launching a meaningful and sustained collaboration with Dr. Berger at UVA,” Zhang said. “Since the start of this project, we have co-developed and submitted 3-4 research proposals to National Science Foundation, Department of Energy, and USDA over the past year, some of which were directly inspired by the findings of this 4-VA initiative.”

George Mason hackathon team turns heads online with award-winning cat robot Teresa Donnellan Mon, 11/17/2025 - 09:22

George Mason Ģ��AV’s College of Engineering and Computing (CEC) made a splash on an online stage when students from four different departments joined forces to compete at Saucethon 2025, a hardware-focused hackathon hosted by Open Sauce and the National Havoc Robot League. Their second-place finish didn’t just earn bragging rights—it highlighted the CEC’s breadth of expertise and collaborative spirit for thousands of viewers following the event online.

The challenge began with a $500 combat robot kit and a mission: modify the base design to complete a rescue scenario in an apocalyptic setting. YouTubers Michael Reeves and William Osman participated, filmed, and commentated throughout the event, amplifying the competition to thousands of viewers.

“Usually hackathons are software focused, so building a robot was so much fun,” said computer science major and Honors College student Alexia Marie De Costa. “The challenges were really fun as well.”

Majoring in computer science, electrical engineering, mechanical engineering, and information technology, respectively, the team joined forces with two other participants, a virtual reality specialist and a programming expert, to develop a cat-themed design.

“I decided that I wanted to add cat ears just because I thought it’d be cute,” said information technology major Irene Ashma Hossain. Those playful touches evolved into practical enhancements: static paws for herding, a pan-tilt tail for maneuverability, and modified wheels for stability.

“It ended up being really effective,” said De Costa.

The 24-hour event tested endurance and ingenuity. Against a backdrop of camera crews and livestreams, George Mason’s team stood out for its creativity and adaptability. Even after a late-night power outage forced participants to improvise, the team completed two rescue runs, performing “emergency surgery” with duct tape between rounds. Their determination paid off: second place, ahead of the prominent YouTubers’ team.

“We were really just having a lot of fun building, so seeing it succeed was exciting,” said De Costa.

By blending creativity, technical skill, and resilience, the team demonstrated George Mason’s interdisciplinary strength, innovative mindset, and ambition.

“This experience was really, really fun,” De Costa reflected. “We’re definitely planning to attend the next one—and maybe even host it closer to Mason.”

Northeast Program Manager), Cassidy Worzalla (student), Dibyashree Basu (student), Shani Ross (senior design instructor), and Gabriel Gibson (student). Photo provided

Miami-based nonprofit Project S.E.R.V.E. (Student Engineering for Resilience of Veterans and Emergency Responders) helps wounded responders get back on their feet and gives bioengineering students valuable hands-on experience in the prosthetics field at the same time. It has sponsored prosthetic limbs for more than 1,300 veterans and first responders from more than 2,000 students since its founding in 2009.

In May, the nonprofit (formerly known as Quality of Life Plus) brought eight teams together for a national competition in Blacksburg, Virginia. Universities from Ohio, Florida, New Jersey, and Virginia gathered to see who could design a prosthetic socket and liner that would mitigate heat and moisture for lower limb amputees.

George Mason’s team comprised Gabriel Gibson, Cassidy Worzalla, Dibyashree Basu, and Kunaal Jindal, all bioengineering majors. Over the course of two semesters, they developed, tested, and evaluated multiple prototypes. They also had to present their progress and proposed solutions twice in fall and once in spring to a group of stakeholders, including prosthetic wearers, for feedback. 

On May 3, the day of competition, Team 7 presented their solution: a silicone liner made with a thermal conductive polymer and containing moisture-absorbent strips. They were judged on two different real-time tests: how much the design lowered the temperature, and how the design helped control temperature and humidity levels when a test subject performed a physical activity.

“The judges liked the innovative design and thought their idea was creative and promising,” said Shani Ross, the senior design instructor and bioengineering associate professor. “We are very proud of the work that the team did. They showed ingenuity, tenacity, and teamwork and represented George Mason Ģ��AV well.” 

Their product helped them take third place—and contributed to the science of prosthetics, and a better quality of life for affected heroes.

Forged in passion, not just fire: This alum is on a hot streak  Shayla Brown Mon, 10/27/2025 - 14:20

Keeping his nose to the grindstone is not just how Andrew Hutsell approaches his academic career in engineering—it's how he cut a small slice of fame.  

The George Mason Ģ��AV alumnus recently put his engineering skills to the test on national television, competing in an episode of the History Channel’s Forged in Fire, a competition show that challenges bladesmiths to create weapons under tight deadlines.  

Hutsell (second from right) and the Forged in Fire judges. Photo provided.

Hutsell, BS Mechanical Engineering ’23, appeared on the episode “Junkyard Meltdown” on September 17 (S10E27).  

 Hutsell’s journey began when one of the show’s judges posted a casting call on Instagram.  

“I was still a student at the time, so they asked what I do at George Mason, what I do in my free time, and to provide examples of the knives I’ve made,” said Hutsell, who also was president of George Mason’s club baseball. 

Hutsell has been a fan of the show since 2016 and started bladesmithing in 2019.  

“Ever since I started making knives, I have only had one goal with each knife I make: learn at least one new skill or method [for the trade]. With this mindset, it is easy to see how my skills have improved over time,” said Hutsell. 

After multiple rounds of interviews, he got the call to appear during a midterm exam.  

Filming took place in March and April 2023. Hutsell described the show’s format as similar to Chopped, but instead of cooking, contestants forge knives through three rounds of competition.

For the last round, judges pick a historical weapon, such as a broad sword or katana, and then contestants go back to their hometown to forge it with their own equipment.   

"I traveled back home to Newport News. When I came back, they tested it to determine the winner,” said Hutsell.  

“They tested the knives by chopping through bone for strength, then slicing sugar cane to see how well the edge held up. It was surreal to compete on a show I’d watched for years,” said Hutsell, who came in second place.  

Hutsell is currently a graduate student at Virginia Commonwealth Ģ��AV working on similar topics such as fluids research.  

“The research that I’m doing is for thermal hydraulics—the cooling system—of molten salt [nuclear] reactors, researching the gas sparring of fission products of molten salts for molten salt reactors,” said Hutsell.  

Hutsell was influenced by Jeffrey Moran, an assistant professor in the Department of Mechanical Engineering, who Hutsell describes as a “a big influence on my work with heat and mass transfer,” as well as Juan Cebral, an associate professor in the Department of Bioengineering.  

“It is always very rewarding when a student demonstrates this passion for learning and dedicates substantial time and effort to master the material to reach high levels of achievement,” said Cebral. “Andrew was one of those students who is dedicated to solving complex problems. His perseverance and motivation will certainly help him make important contributions in his field.”

Podcast: The modern grid: the intersection of energy and the environment Sarah Holland Mon, 10/20/2025 - 11:00

“Infrastructure” is one of those words that can mean a lot of different things to different people. At George Mason, we’re focused on infrastructure in terms of sustainability – how can we help innovate new systems for the world’s infrastructure that will be resilient and flexible enough to support a changing world.

On this episode of Access to Excellence, President Gregory Washington is joined by two guests working at the intersection of innovation and sustainability to develop George Mason’s capabilities as a living laboratory for students, faculty, and staff to find solutions to our grand challenges: Liling Huang, associate professor of electrical and computer engineering in the College of Engineering and Computing and the Dominion Energy Faculty Fellow in Power and Energy Systems, and Leah Nichols, executive director of the Institute for a Sustainable Earth (ISE) in the Office of Research, Innovation, and Economic Impact.

The living lab, what I see, it's beyond the lab. It is a living community, a living society. We can have students actually have...a model startup to run this community, to run the lab, to collect the data, and then to hire students to be the operator. So I think this is even beyond lab, and it also brings in multidisciplinary collaboration between engineering, science, business and policy. – Liling Huang

We are now experiencing more intense storms, greater and longer durations of heat, shifts in seasonal patterns. However, a lot of our infrastructure was built decades, if not centuries ago...And so there's vulnerabilities, and we need to start accounting for how the changing climate and the information that we're receiving now about how the ecosystems are working and the physical systems are working into managing the infrastructure and the systems that comprise communities...Identifying opportunities to make changes to ensure that our systems are sustainable and can withstand the consequences or the more extreme weather and the different weather and climate effects that we're experiencing now is really important. – Leah Nichols

Intro (00:04):
Trailblazers in research, innovators in technology, and those who simply have a good story: all make up the fabric that is George Mason Ģ��AV, where taking on the grand challenges that face our students graduates in higher education is our mission and our passion. Hosted by Mason President Gregory Washington, this is the Access to Excellence podcast.

President Gregory Washington (00:26):
Infrastructure is one of those words that can mean a lot of different things to different people. At George Mason, we're focused on infrastructure in terms of sustainability: how we can help innovate new systems for the world's infrastructure that will be resilient and flexible enough to support a changing world. And we're not just talking theory here. My two guests today are at the intersection of innovation and sustainability to develop George Mason's capabilities to be a living laboratory for students, faculty, and staff to find solutions to our pressing grand challenges. Liling Huang is an associate professor of electrical and computer engineering in the College of Engineering and Computing, and she's the Dominion Energy Faculty Fellow in Power and Energy Systems. And Leah Nichols is the executive director of the Institute for Sustainable Earth, or ISE. It is in the Office of Research Innovation and Economic Impact. Leah, Liling, welcome to the show.

Leah Nichols (01:37):
Thank you.

Liling Huang (01:37):
Thank you.

President Gregory Washington (01:40):
Liling, your work focuses on securing the nation's critical energy infrastructure. Can you tell us a little more about what this means and why it's important?

Liling Huang (01:53):
Energy is a backbone of our national security, our economy, sustainability, our community trust. So without the energy we cannot have data flow, we cannot run hospitals, we cannot run data centers. So it is very, very critical infrastructure for our modern life.

President Gregory Washington (02:17):
So what kind of threats do you see that our energy and infrastructure face?

Liling Huang (02:23):
Our infrastructure is facing many challenges, uh, including the aging infrastructure. Our energy infrastructure was built more than a hundred years ago. It is aging and needs to be modernized. We also facing challenges of cyber physical attacks, we also facing challenges of the workflow shortage, the supply chain shortage, the challenge of incorporating the renewable energy into the power systems.
President Gregory Washington (02:54):
I see. Have we taken some major steps as a country or as a region to secure our energy infrastructure?

Liling Huang (03:02):
Yes. I think the public private sector are working together along with the government to secure the energy infrastructure by upgrading our infrastructure, investing in workforce development, uh, as well as bringing a more diverse energy portfolio to the system.
President Gregory Washington (03:24):
Well, that's more easily said than done, right? When you start to talk about diverse energy portfolio, that could be many other diverse energy pieces bring their own set of problems, right?

Liling Huang (03:36):
Yes, exactly.

President Gregory Washington (03:38):
So one of iscs key programs is Mason as a Living Lab. And that whole entity aims to stimulate and support the development of research and scholarship that use the campuses and their physical and social ecological structures for implementation in education. And that framework seems to be working really well. Leah, can you tell us more about how this initiative came about?

Leah Nichols (04:03):
Sure. Happy to. I came to Mason about five years ago to to run the Institute for a Sustainable Earth. And a core mission of the institute is to help put research into practice. So the campus itself is effectively a small city. There's over 48,000 people on the campus, a population that that utilizes the campus, some of whom live here. It embodies all of the different types of infrastructure systems that are required to support and maintain that population. So it's an ideal microcosm with which to engage, to study the socio-environmental technological ecosystems that make up this small city. And then it's also a microcosm within which we can develop solutions, test solutions, use it as a test bed, create some demonstration projects that could then be scaled into solutions in communities elsewhere and around the globe. So it was my first target to create opportunities to put research into practice.

Leah Nichols (04:54):
I reached out to Dr. Greg Farley, who's the director of sustainability, and he and I really jived on this idea. We really liked this idea and wanted to lean into it. So we looked at what all was going on already on campus and how faculty and students were utilizing the campus for research. Um, and learned that there was a lot going on. Our faculty are innovative and they wanna see their research put into practice. Um, but all of those projects were being, being done on an ad hoc basis. The wheel was being reinvented over and over again. And so Greg and I put our heads together along with Frank Strike, vice president for, uh, facilities and operations, campus operations, and Andre Marshall, vice president for research, to really develop a program that standardized protocols that effectively built a bridge between the research community and the facilities and operations communities. So this type of research activity could go on much more smoothly, be amplified. We also created a data sandbox to capture the data that was being collected about the university so that it could be shared across units with others who are interested in, in similar sorts of research projects.

President Gregory Washington (05:57):
Well, let's talk about scale and, uh, be a little more pragmatic. Can you gimme an idea of what kinds of projects have gone through this process? You know, just talk high level in terms of what they are and what they, what they're supposed to do.

Leah Nichols (06:12):
They do range and scale, and we have provided seed funding to, to support some new projects. Uh, they and those typically are on the order of, you know, tens of thousands, um, or so to support students and faculty who are getting ideas off the ground. Some of them are very large projects, not ones that we supported, but ones that we definitely amplify as the, that are international recognized arboretum, which has a massive amount of data about the trees on campus. Um, and like I said, internationally recognized, but we also supported very smaller scale projects. One of our very first ones that came through the new program is the Cherry Blossom Monitoring. And the math department has stood up a, a global competition where they're working with students who, um, to do statistical analysis to predict when the cherry blossoms are gonna bloom here in DC at Mason, I think in Japan, there's a couple of other international sites.

Leah Nichols (07:04):
It's, it's, it's now taken on a life of its own, but we were able to put in place working with facilities, cameras to monitor the, the, the blooms there. We also have a small project that we just funded this year that I'm, I'm quite excited about. Dr. Changwoo Ahn is taking on analysis of a corner of the campus that used to be an intermittent wetland. It's now turning into, um, a permanent wetland. And that transformation process is something that's not well studied. Um, so it creates opportunities there, but it's also of interest to the, the campus operations. Understanding this change process will help them better manage the, the wetlands and the ecosystem that's, that's emerging in this space. So, very exciting.

President Gregory Washington (07:42):
So Liling?

Liling Huang (07:43):
Yes.

President Gregory Washington (07:44):
While your smart grid lab is independent from ISE, if I'm not mistaken, right? The project is working towards a similar goal. Right? So we got two living lab concepts. So talk to me about each one of you. What does it mean to be a living lab?

Liling Huang (08:03):
To me, a living lab, it is the platform to close many, many gaps between the industry and academia, within the academia, between the students, the faculty, the staff. It's, it is a platform can bring everybody together as a community, and especially at Mason to achieve education and research.
President Gregory Washington (08:31):
Talk a little bit about how the project support experiential learning of our students.

Liling Huang (08:37):
It's bring our student, uh, career ready and build their teamwork problem solving, and it builds their confidence because they operate, they experience that they bring the theory into practice. I think it's very, very important to our students, not only to recruit, but also to retain and to advance. And I think it also will put Mason as a leading position in all the aspect. It's a very, very important tool for, for Mason and for our students.

Leah Nichols (09:15):
I would agree. Uh, a lot of faculty do take their students out of the classroom and utilize the ecosystems, the campus grounds to gather data. And while their students are learning about the tools and the data collection methods and the analytical methods for studying these types of systems, and, you know, with our lab. But we're hopeful we, we have some faculty who are already feeding this data that their, their students are collecting in courses into the data sandbox that starts to create a longitudinal data set of, um, similar sorts of data collection, um, over time. But the more that we can get, um, and encourage our faculty to get our students out utilizing the campus to develop their research skills, to develop their understanding of, of socio-environmental system theory, et cetera, is, is really exciting.

Liling Huang (09:56):
And to me, I think the, the living lab, what I see, it's beyond the lab. It is a living community, uh, living society. We can have student actually have a startup, a model startup to run this community, to run the lab, to collect the data, uh, and then to, to hire student, to be the operator. So I think this is, uh, even beyond lab, you know, like, and it, it also bridge, uh, brings in multidisciplinary collaboration between engineering, science, business and policy.

President Gregory Washington (10:33):
Well, the problems that we have to deal with today, especially in the energy space, are all multidisciplinary, right?

Liling Huang (10:41):
Mm-hmm <affirmative>. Yes.

President Gregory Washington (10:41):
They have the technical aspects. Which are very clear. You have the social economic aspects, which in my opinion are very, very clear. And you got the political aspects which are not as clear <laugh>, uh, at least on some things, but are still clearly there, right? So, Leah, your role at the ISE is specifically around developing connections across communities to put George Mason's research and scholarship into action in support of a sustainable world. So what does it look like to build those bridges across discipline?

Leah Nichols (11:17):
Yes.

President Gregory Washington (11:18):
And talk a little bit about the receptivity on campus to building those bridges amongst our faculty and, and our, and our researchers and the like.

Leah Nichols (11:27):
Sure. Um, I was gonna say, I'm gonna go one step further and say we're building bridges across academic disciplines, but we're also working to bring external partners, people who are interested in co-designing, co-developing solutions, um, that they're experiencing in their, in their lives with local governments, local, you know, local businesses.

President Gregory Washington (11:44):
Yeah. Sometimes they can be, for lack of a better way of putting it, easier to build relationships with than the entities right here on campus.

Leah Nichols (11:51):
That can be true.

President Gregory Washington (11:53):
A couple of nights ago I had dinner with one of the founders of Nvidia. And at that dinner, they were talking, of course, they were extolling the virtues of their AI chips and the super computers that you can build from these AI chips. And one of the things that he talked about really piqued my interest that just immediately came to mind listening to you all talk about bridging the divide. Their belief is that some solutions are hyperdimensional, right? Meaning there's so many layers of possible connection that we just may not be able to see. It may not be able to draw the connection to inner city social science issues and next generation solar. Right. But that computers, especially those equipped with, uh, uh, AI generated tools, can actually explore well beyond our realm of seeing an actual problem. And so I just wanna get your reaction to that relative to this transdisciplinary work and finding solutions that right now aren't obvious to us.

Leah Nichols (13:03):
So you really hit on something I'm also excited about. One, one of the things I was doing while I was at the National Science Foundation and was trying to fund science that would advance our understanding of these complex system interactions. And the advances in the technology have really unlocked that ability. You know, science hundreds of years ago through relatively recently, was focused on a reductionist, like, let's break it down to the smallest, smallest, smallest parts to really understand what's going on. Valuable, but at like, now, we can really look at systems and try to interrogate what's the causality? Can you explain causality within systems? So these types of tools really allow us to interrogate these complex systems in really new ways, which could very much reveal opportunities to adjust to, to where to take action, how action in some spaces will potentially propagate into action. Uh, you know, this is a new area of science. I'm not, I'm not saying that we're gonna be able to explain every complex system, but what an exciting avenue of science is, is to be interrogating the complexity instead of the smallest pieces.

Liling Huang (14:03):
Yeah. I, I think that we, a a unit, an institution, we have a very limited time to learn. Very limited view. And yes, AI does provide a potential to be able to look at everything holistically, maybe come up with a good solution. But personally, I always think that, you know, everything has, it's, it's always two folded. On one side, it has one and has a zero. So I think it, it brings opportunity, but also we want to know the challenge that AI bring in to the society. So we still need a human, human in the loop to help AI do a better job. You know, we are human being, we want to have a better life. So we don't want the whole world to become just machine, just AI. So the human in the loop is very important. Uh, and that also, like all the AI computation, again, I'm the power person. So I would like to say the challenge that the AI computation bring in is the humongous energy demand to support those AI computation, and that huge energy demand is part of the challenge to our infrastructure, the impact to the environment. So how do we solve those complex problem? It's very interesting.

President Gregory Washington (15:23):
Oh, I hear you. I hear you.

Leah Nichols (15:25):
I think AI is an exciting tool, but fully agree that you have to use it cautiously. Any type of science, any type of tool, how is it gonna get used and how is it gonna be put into practice and changing the world around us. So things to think about the,

President Gregory Washington (15:37):
The challenge is that cat might be out of the bag right now, you know? So look, you both have work experience outside the academy, right? So Leah, you spend time at National Science Foundation; Liling, you were a certified, uh, professional engineer at Taiwan Development and Trust Corporation before pursuing a PhD. And so talk about those experiences and how those experiences inspire your move into higher ed, but also how those experiences are helpful for you today.

Liling Huang (16:08):
So I think it's a very valuable experience. Uh, like I work in industry and I see the challenge in industry, which the student will be, uh, facing, you know, in their career. So I see the gap between the industry and academia. I remember when I first report to, uh, my manager, I have to learn everything, you know, start from the beginning because it's, I learn all the theory. So I kind of see the importance of hands-on, practical. Uh, and also I see that the, the importance and actually to run the infrastructure, human is also, I would say like the operator. The engineer is very important and very critical part of the infrastructure. So I see the gap and I see the importance of having a skillful engineer workforce. And that's why, uh, inspire me to build a career in academia because I think that, uh, it is a very prestigious position to train and educate a future engineer. And that experience helped me to better embed, improve my teaching, uh, education and research to be able to bring in the practical challenge and experience into the education and research.

President Gregory Washington (17:31):
Interesting.

Leah Nichols (17:31):
So while I was at the National Science Foundation, one of my primary roles was to help build and design these multidisciplinary, and transdisciplinary types of funding programs to fund different types of science. Again, focusing predominantly on socioecological systems and the, the role of, of those systems and how those are changing. And then toward the latter part, while I was engaged with an advisory council, they gave us very strong advice. Like we're, we've been describing the challenges of the world for a while, quite a long time in the socio-environmental systems. What do we start doing about it? And that really helped drive me to think about like, what type of science needs to be done so that we can start taking action to address these grand challenges, these wicked challenges. And as a, a program officer, I was facilitating those sorts of dialogues across disciplines so that I bring back to the table here at Mason, getting lots of people with very different worldviews in the same room to come to a, a common understanding of need and opportunity and ways that we can support, uh, science to develop solutions in these space. I was also often one of the voices in the room saying, how do we bring the spaces of research use into the, the scientific questions or the science that we're funding? How do we get use-inspired science where community partners or industry partners are, are deeply engaged in development of the science itself or the co-design of the science.

President Gregory Washington (18:50):
So one of the solutions in our grand challenge initiative is George Mason at the center of building a climate resilience society. Now, you two sit in different components of that spectrum, right, of building a climate resilient society. And so as two researchers dedicated to innovation and sustainability, what does climate resiliency mean to you? Right. And what do you see as the grand challenge in your space?

Leah Nichols (19:18):
So a climate resilience society, I, I will say, you know, we are in the throes of climate change. We are now experiencing more intense storms, greater and in longer, and durations of heat, shifts in seasonal, um, patterns. However, a lot of our communities, as, as, uh, Liling was saying earlier, a lot of our infrastructure was built decades, if not centuries ago, uh, well before climate change was even underway or understood to be underway. And so there's vulnerabilities, and we need to start accounting for how the changing climate and the, the information that we're receiving, um, now about how the ecosystems are working and the physical systems are working into managing those, the infrastructure and the, the systems that comprise communities. That means understanding and like really looking at where are the risks? What types of changes in the flood patterns or the rainfall patterns or the heat indices, where are those gonna cause the most damage?

Leah Nichols (20:18):
And then how do we start, um, mitigating that type of damage? What interventions do we need to put in place so that when events happen, when significant rainfall happens and floods occur, infrastructure and people are outta the way not damaged? Or what can we do to make sure that those systems are, can sort of go down for a short while and then come right back up? They're not being destroyed. So identifying where there's risk, identifying opportunities to make changes to ensure that our, our systems are sustainable and can withstand the consequences or the, the more extreme weather and the, the different weather and climate effects that we're experiencing now is, is really important.

Liling Huang (20:58):
And to me, I think Leah meant, you know, the cause--it's very, very important, like to build a climate, uh, resilient society, we need to understand and the cause and to observe the pattern, and from the engineering perspective, from the energy infrastructure, we need to know if we are part of the cause, how do we improve that? How do we reduce that from the design operate perspective to support that? And also, when this type of extreme weather occurred, how can we continuously provide reliable energy? Because that's the backbone of everything, of our daily life. So to build a resilient climate, uh, you know, uh, society, I, I see that all our six grand challenges touch this topic. And this is actually the core to connect all the six challenges together. We need the 21st century workforce, uh, to build a climate resilience society. We need the digital, we need the AI, we need a healthcare system, we need everything. And then our grand challenges right on top of that.

President Gregory Washington (22:11):
Okay. Well, let's <laugh> let's dive into this a little bit. This whole concept of building a climate resilient society really is not about understanding climate change from the perspective of whether it's manmade or whether it's just a natural artifact of the changing cycles in the way our planet is progressing. It's really about saying whatever's causing it, we have some challenges, right? We have major challenges on both coast <laugh>. One can't get enough water and it's burning, and the other one is literally getting too much. And, you know, we've had multiple 500, uh, year biblical floods in a number of locations. This is about what happens as we deal with the aftermath of climate change, building a climate resilient society. Our climate is changing. Our society has to change in order to accommodate it. And so, yes, everything you guys highlighted, we need faculty, we need folk trained properly in order to manage this.

President Gregory Washington (23:25):
Right? But what I'm getting at here is: talk a little bit about deal with the political issues that may be dividing us on the causality aspect of this problem. How do we get away from that and focus on the fact that, look, I don't care what your belief is, you're flooding and we need a solution for that. We need a a new home type system for that, or we need a solution to help you mitigate that, or a warning system to keep you out of that. Or communications framework that helps you to understand when these things are coming so you can react. Talk about that a little bit.

Leah Nichols (24:04):
The, what you were just saying is essential. We need to address the problems of today, as you just said, coasts are being inundated, communities are being destroyed, literally, um, quite literally. Um, and in a repeated way, both from wildfires and extreme like downpours and flooding in, in places that you would not expect floods to happen. And it, it's happening outside of the floodplains that we understand from before. Severe wind and tornadoes are taking down, you know, there's a lot of damage to infrastructure and people and livelihoods all across the country. So we do need to be addressing the challenges that we're experiencing today. I think one of the things that we need to do differently is a lot of the, like I said, the, the prior infrastructure and the risk assessments are typically looking retrospectively. Like what has happened in the past that we need to plan for now.

Leah Nichols (24:52):
Like you, you mentioned 500 year floods. In the past, those types of floods did happen once every 500 years or so. Now, the science is able to, to, to provide some predictions about what the future trends are going to be in these areas. And so in order to plan and, and address infrastructure challenges of today, we should be looking at what the best available science is telling us about where things are going so that we can start accounting for that in, in the way that we build our infrastructure systems. I mean, you might say climate science, but you, you might also just say, this is best available science of how many floods are gonna happen.

President Gregory Washington (25:27):
Or, this is just community planning now, right? Look, if, if the flood plain is shifting and it's going to be here now, it's not build the homes there, let's shift them and build them a mile two miles away, where it might've been a problem previously, but maybe it's not that now you, you, you get what I'm saying?

Leah Nichols (25:47):
And it's, some of it's the floodplains that themselves are shifting, but a lot of what's happening now is this heavy, heavy, heavy downpours, you know?

President Gregory Washington (25:53):
No, I, I get it. I get it. I mean, places that were flooding previously, this is what happened with the young people in, uh, in, in Texas. Texas, right?

Leah Nichols (26:04):
Yes, that was terrible.

President Gregory Washington (26:04):
You know, look, the reality is is that the, the area always flooded. And that's why nobody really worried about it too much. But we live in a different time now. We need tools to predict that. We need tools to say, Hey, based on our predictive models, what's coming is not what you saw five years ago, 10 years ago. This is different. Get out. Right. And so that's the kind of thing that I want us to get to as we build a climate resilient society. Liling, I I know I interrupted you. Go ahead.

Liling Huang (26:36):
No, no, you're good.

President Gregory Washington (26:38):
Uh, I, I, you know, because youre, you're in the, you're, you are literally in the core space of this with energy production.

Liling Huang (26:44):
Yes. As long as they are human activities, we impact the environment, but there's no way we'll go back to live in the cage, uh, without electricity, going back to, you know, millions years back. So how do we better design and, and live in the environment to reduce the impact? And President Washington, you mentioned, like, to design a climate resilient society is not just the science, not the engineering, but it's the society. My experience, my view is a lot of community, they do not have the access to the data, to the fact people make decision based on the feeling, their perspective, a very limited perspective on maybe just economy or maybe just political or, you know, they, they all look at a smaller set of their view and, which cannot solve the problem. Uh, you, you see, like even the energy policy, you roll out the energy policy for the next five years, and all of a sudden you change, and then who knows, then next five years it change again.

Liling Huang (27:56):
I think what the, the challenge is, uh, to have a holistic view of the multidisciplinary: from the social, from the business, from the political, from engineering, from science. And again, the core is the community, is the human. So I think that's actually what I see, the, the challenge. And then I think that we have the responsibility to deliver the message, uh, to deliver the holistic fact and data to inform that, you know, this is going to happen if you don't take this action. And then I think everyone is responsible, you know, on the building the resilient society.

Leah Nichols (28:39):
I was also gonna add, 'cause I, I, I didn't talk much about mitigation of climate, the carbon dioxide into the atmosphere, but that is something we might wanna be very, very thoughtfully considering as we address climate resiliency. Things that keep me up at night are, um, you know, we have trajectories and the science is starting to tell us that some systems are going to start collapsing. And we're talking about like ocean systems and sea level rise, and well, what's gonna happen to our agriculture system? I mean, there's some of these existential challenges that might be on the horizon that we're still working on getting the science about when is that gonna happen? Is that gonna happen? Those sorts of things. But there is signals that we do really need to be addressing how much carbon dioxide we're putting into the atmosphere so that we hopefully keep us below some of those tipping points. We'll see.

President Gregory Washington (29:24):
As we move forward here. And, and if you were to be having conversations with our young people today, as you do in the classroom and beyond, or even with our faculty as, as we end, what are some of the ways individuals can help create climate resilient communities and ensure sustainable future?

Leah Nichols (29:43):
One of the most effective ways of, of creating resiliency within a community is, is actually reaching out to your, your neighbors and your community. Understanding where people are vulnerable, helping them address those vulnerabilities if and when possible. Recognizing that you, you might wanna go up the street and check on somebody in, in the context of a disaster so that you can help them create some resiliency. The more that we connect and create community, the stronger those communities are, regardless of the infrastructure. Though, ideally you also are engaged in the processes that will upgrade and, and increase the resiliency of the critical infrastructures of those communities.

Liling Huang (30:18):
Yeah. Uh, for me, I always encourage my student and emphasize the importance of having a critical thinking skill. They are the future, uh, generation. They're the future engineer to build the system, to operate the system. So critical thinking, skill and teamwork, it's very important. Uh, one person cannot solve a problem. You need a team. You need people from different skillset, from different perspective. Also, to be able to work with a team to drive the innovation and critical thinking. Uh, you don't always believe what you hear. Right. You have to be able to critically evaluate before you accept it. I think that's very, very important. Not just, you know, uh, receive what we were told and then execute that. I think critical thinking, very important. So you don't be influenced or misled easily.

President Gregory Washington (31:16):
Understood. Understood. Well, look, this has been fantastic. Last point. Just quickly, lightning round. What's given you hope for the future?

Liling Huang (31:27):
I think the, the hope of the future, uh, is our next generation. It is here, Mason, our faculty, our student. I think that's the future. And then the infrastructure side, you know, the research, and again, our theme, like our living lab that give us hope of the future.

Leah Nichols (31:48):
What gives me hope is, is the amount of people who are working hard to solve these types of problems. You know, faculty as well as students in the next generation, despite significant headwinds in some contexts. There's, there's a lot of people in the world in the United States and, and far beyond that are really committed to, and digging into solving these sorts of challenges. And that's the only way things are gonna get done, is we just keep on working, keep on designing. I think there's, there's a lot of opportunities to innovate. I just look for the people who are doing things, good things, um, and there's a lot of them through the living labs and through the Institute for Sustainable Earth, always wanting to help and support those individuals here in the Mason community and beyond.

President Gregory Washington (32:31):
Outstanding. Outstanding. Well, we're gonna have to leave it there. Liling and Leah, thank you both for joining us today.

Liling Huang (32:39):
Thank you.

Leah Nichols (32:40):
Thank you so much for having us.

Leah Nichols (32:41):
Thank you so much. I am Mason President Gregory Washington. Thanks for listening. And tune in next time for more conversations that show why we are all together different.

Sungsoo Ray Hong

Yotam Gingold

George Mason Ģ��AV Information and Sciences (IST) Assistant Professor Sungsoo Ray Hong has always loved cartoons. Now he’s helping the artists who make them.

Drawing on his expertise in human-computer interaction (HCI) and artificial intelligence (AI), Hong and colleague Yotam Gingold, an associate professor in the Department of Computer Science (CS) created ShadowMagic, a new human-AI collaboration tool designed to make one of the most time-consuming parts of comic creation faster and easier.

The idea for ShadowMagic emerged from interviews with professional cartoonists. Hong, Gingold and their PhD students wanted to reduce the burden of shadowing, a task many artists find repetitive and time-consuming.

“Professional cartoonists are sometimes producing content every other day,” said Hong, who is also director of George Mason’s Alignment Lab. “You cannot commit to these kinds of deadlines doing everything by yourself. That's why the colorization industry is so helpful to professional cartoonists.”

Colorization is a multi-step process of line drawing, flatting, base colorization, adding shadows and lighting, backgrounds, and other special effects. It is “fairly standardized, especially in South Korea and growing throughout the United States,” said Hong, who is from South Korea. ShadowMagic builds on an earlier project, FlatMagic, another AI-driven colorization tool designed to support digital comic professionals.

While there are existing AI tools that help with colorization, Hong and Gingold found that these tools require more work than doing it manually. They wanted to design a system that better augments cartoonists’ work and cuts down on shadowing, a labor intensive and, according to cartoonists, decidedly uncreative part of the process.

“We looked at artistic challenges, usually tedious things that aren’t so fun for the artists and break down those problems, so that they can focus more on the creative parts of it,” said Gingold, who directs George Mason’s Computational Reality, Creativity, and Graphics Lab.

Gringold explained that there are millions of pixels in an image, and if an artist wants to move or change the color of an object, they currently have to point at one pixel among the millions.

Gingold’s research applies computer science to visual, geometric, and design problems. He has “always been interested in sketching and how computers can help us express ourselves.” Many of his algorithms automate filling in pixels and handling visual constraints.

“The computers will do the math where we can write formulas to update all the other millions of pixels. Another example would be keeping lines parallel and corners perpendicular, and that’s where a lot of my research comes in,” he said.

Chuan Yan, PhD ’24, was recruited by Gingold for this project and conducted research on sketching and painting. Yan, now a postdoctoral research at Stanford Ģ��AV, brought expertise in computer graphics and sketch-related computer vision techniques, which he had studied extensively with Gingold.

The team built ShadowMagic as an Adobe Photoshop plug-in, and since its release, it has attracted a lot of interest from professional artists.

“Artists have expressed a strong desire for a tool that could free them from the labor-intensive flatting process,” said Yan. “This response is both exciting and humbling. It confirms that our research is addressing a real need in the industry yet also highlights the remaining challenges in making [the tool] ready for widespread adoption.”

Yan believes ShadowMagic is just the beginning of a broader shift in creative industries towards tools that amplify creativity rather than replace it.

“I am excited to witness and contribute to this transformation, helping to shape a future where AI acts as a powerful tool that amplifies human creativity rather than replacing it,” he said.

Read the full paper: ShadowMagic: Designing Human-AI Collaborative Support for Comic Professionals’ Shadowing by Amrita Ganguly, Chuan Yan, John Joon Young Chung, Tong Steven Sun, Yoon Kiheon, Yotam Gingold, and Sungsoo Ray Hong. It was presented at UIST 2024.
