You’re managing the Texas Panhandle’s power grid. Heavy winds are blowing, and a worn-out utility pole ignites a fire by crashing onto a transmission line. Luckily, the fire department arrives quickly, putting out the fire before it spreads to nearby cities. But the same thing may happen again with gusty conditions predicted for the next 24 hours. Should you shut off miles of power lines to reduce that risk, causing outages for thousands of residents? Should you add batteries to the grid or move some power lines underground to lessen the impact of future fires? That sounds useful, but paying for these upgrades would require raising electricity rates.

Players of the Current Crisis video game are pondering these questions, similar to professional grid managers during the Texas Smokehouse Creek fire in 2024. But the players did not purchase Current Crisis at a run-of-the-mill gaming store. They might have played it at Georgia Tech’s Dataseum, which featured the game in a recent exhibition. Or they might have helped develop it in weekly meetings with Daniel Molzahn, associate professor in the School of Electrical and Computer Engineering and EPIcenter initiative lead. 

“Current Crisis started as a computer simulation I programmed in Summer 2020 for a senior-level course I taught that fall,” says Molzahn. “My students had to dispatch crews to maintain or repair a simplified model of the Georgia power grid. In the middle of the Covid-19 pandemic, each dispatch had a risk of infection and quarantine, which meant losing the crew for the rest of that round. The students had a fixed budget to balance two competing goals: operating a power system with minimal outages and keeping the repair crews healthy.” 

The class project was popular, and its scope began to grow. Molzahn proposed turning his simulation into a video game in a July 2021 grant application to the National Science Foundation. He received the five-year award that fall and launched his “Vertically Integrated Project” on power grid gaming the following spring. It soon attracted about 35 students per semester, from sophomores to those pursuing graduate degrees in various disciplines. Most students stay for three to four semesters.

Tristan Ziegler joined the VIP as a computational media sophomore in Spring 2022 — and still works on it three years later as a professional programmer. “I found the project by searching for ‘game’ on the VIP website,” says Ziegler, who graduated in 2024. “It offered much more freedom than traditional classes but still allowed me to earn credits and grades, unlike a student organization where you volunteer your time.”

The students quickly discovered the benefits of working toward a shared goal in smaller groups, focused on coding, grid modeling, graphic design, or artistic creativity. Some volunteered to lead initiatives, such as organizing the Dataseum exhibition or the 2025 Seth Bonder summer camps, where they will teach high schoolers the basics of game programming. 

Another long-term member of the VIP team is Ryan Piansky, a doctoral student, who studies the resilience of power grids to wildfires. He combines well-known engineering tools — algorithms for finding a mathematically optimal problem solution — with historical wildfire data to evaluate grid management decisions.

“I have examined if policies based on established engineering principles help the people who need the most help, reduce the risk of outages broadly across the whole grid, and optimally allocate limited resources,” explains Piansky, who works in Molzahn's research lab. “To do that, I combine power grid models with realistic wildfire simulations to assess if those policies would likely generate desirable outcomes in a range of plausible scenarios.”

The VIP work on grid modeling has informed Piansky’s research, but the climate models he uses to mimic the spread of wildfires are too complex for a fast-moving video game. That’s why he has helped the students develop simplified versions of these models. Humidity and vegetation, for example, influence both real fires and those popping up in Current Crisis. 

Piansky’s research is part of Molzahn’s long-term goal: developing computer tools that help professional grid managers improve the grid’s resilience to natural disasters — from pandemics and wildfires to hurricanes, heat waves and floods. 

“We plan to record the choices made by Current Crisis players in crowdsourced datasets that will support our research,” says Molzahn. “By using these datasets to train machine-learning algorithms, we can harness the power of AI to develop better disaster response policies.” (The European Space Agency uses a similar gamification strategy to map moon craters.) 

The project’s benefits go well beyond these research contributions. Its educational value includes experience working in multidisciplinary teams of students at different levels and leadership development. Molzahn also hopes the game will help build public acceptance of disruptive actions during real disasters. 

“Recognizing the tradeoffs inherent in grid management is important, whether it’s understanding why power shutoffs reduce fire risks or why service restorations are time-consuming,” says Molzahn. “This may also generate broader public support for electricity rate increases and tax allocations to pay for infrastructure hardening.”

Jack Rose, Junior, Computer Science

Why did you pursue your startup? 

Rose: I’ve been into cars my whole life. Trying to track cars is my hobby. There are always edge cases, and how are you planning to attack them? Because I spent so much time, especially working with other people, getting this data, and trying to figure this out, I became very adept at understanding the data. The dealers, collectors especially, were trying to understand the whole story, so they would come to me. But the way I had to do it was spreadsheets all over the place, and I was trying to find a solution to keep it all in one spot. I couldn’t find a way to do it, so I said, “Well, I’ll build it.” And then I got into I2P.

What was challenging about building your prototype over the semester? 

Rose: This semester, it was mainly trying to come up with the schema and how to physically account for the edge cases. It’s not easy; it took a lot of deep thought, discussions with other people who are into these niche cars, and understanding what details we needed. I’m still trying to add more things and figure it out. It’s not perfect, but it’s enough.

What was your favorite part about I2P? 

Rose: Adding features that I was looking for. For example, let’s say I was looking for a car. Filter all the cars over 25 years old and imported to the U.S. — I can easily search my database.

What would you say to students who are interested in entrepreneurship? 

Rose: It’s always, “You should have started sooner.” I’ve always thought about it. My biggest advice is to just start doing it, even if it’s a little bit here, a little bit there. If it doesn’t work out, at least you’ve tried.

A photo gallery from the Spring 2025 I2P Showcase can be viewed on the CREATE-X Flickr page.

Students interested in the I2P program can register for the upcoming summer and fall semesters. The deadline for Summer 2025 is May 14, and the deadline for Fall 2025 is May 16.

CREATE-X's next event, Demo Day, will take place on Aug. 28 at Exhibition Hall, where more than 100 startups will be on display. Attendees can experience the newest batch of founders leveraging the latest technology to solve pressing challenges. The event offers an opportunity to network with entrepreneurs, industry leaders, and passionate enthusiasts, and supports the next generation of innovators. Register for Demo Day today and be a part of these founders’ journeys!  

On a cloudy spring day in Atlanta, Rich Simmons, director of research and studies at the Georgia Tech Strategic Energy Institute (SEI), led a group of a dozen student volunteers to the roof of the Carbon Neutral Energy Solutions Laboratory (CNES). The students were part of the nearly 300 student volunteers participating in Georgia Tech Beautification Day and visited CNES to clean the building’s rooftop solar array made of photovoltaic (PV) panels. The CNES building entered operation in 2011 and its panels have accumulated grime over the years, impacting their efficiency.

Simmons explained the importance of this project, emphasizing how cleaning the panels restores their efficiency and contributes to ongoing research. "We've used this project to better understand PV efficiency in an urban environment and have instrumented the newly cleaned arrays to continue monitoring. An initial study last year suggested efficiency could increase by 10-20% just from a thorough cleaning. This project is both a handy research tool, an educational conduit, and a means of campus engagement related to sustainability," he shared.

Safety was paramount, and proactive communication between the research, health and safety, and infrastructure and sustainability teams ensured a successful event. Equipped with hard hats, eye protection, and high-visibility safety vests, the students scrubbed the panels with sponges and bristle brushes. The hands-on experience was both educational and rewarding.

After cleaning, Simmons led the group to the inverter room, where the DC electricity generated by the panels is converted into AC so that it can be consumed within the building or exported to the campus grid. He explained that excess solar power can also be stored in the newly installed 150-kWh Stryten battery system or used to charge campus vehicles through the newly installed EV chargers in the building’s parking lot. He demonstrated how magnetic monitoring devices measure the electricity produced by the arrays, allowing for a comparison of the efficiency of panels that were just cleaned, to those that were cleaned last year, and those that have never been cleaned in the 13 years since their installation.

Through initiatives like this, Georgia Tech continues to lead in research and education, inspiring the next generation of innovators and problem-solvers.

Two faculty members represented Georgia Tech as new fellows to the world’s leading organization dedicated to applied mathematics, computational science, and data science.

The Society for Industrial and Applied Mathematics (SIAM) selected Elizabeth Cherry and Katya Scheinberg as Class of 2025 fellows. The two Georgia Tech faculty join an illustrious class of 23 other researchers from around the globe in this year’s class. 

SIAM selected Cherry to recognize her contributions to mathematical and computational modeling and extensive service to the SIAM community. She studies the electrical behavior of cardiac cells and tissue.

Cherry’s computer models and simulations improve understanding of cardiac dynamics in normal and diseased states. Using these tools, she designs advanced strategies for preventing and treating arrhythmias.

“SIAM has played a huge role in my professional development—the first conference I attended as a graduate student was a SIAM conference, and I’ve attended at least one SIAM conference almost every year since then,” Cherry said. 

“Given this long history, it means a lot to me for SIAM to acknowledge my contributions in this way.”

Scheinberg, from Georgia Tech’s College of Engineering, was selected for her foundational contributions to derivative-free optimization and optimization applications in data science and her dedicated service to the optimization community.

Cherry is the fifth faculty member from the School of Computational Science and Engineering (CSE) to be selected as a SIAM Fellow.

Cherry’s announcement as a SIAM Fellow comes weeks after serving in a leadership role at a SIAM conference. She co-chaired the organizing committee of the SIAM Conference on Computational Science and Engineering (CSE25).

In 2023, SIAM members reelected Cherry to a second term as a council member-at-large. She began her three-year term in January 2024.

"SIAM Fellows are selected for deep mathematical contributions. Receiving Fellow status is a high honor for any applied mathematician," said Regents’ Professor Srinivas Aluru, senior associate dean of the College of Computing and Class of 2020 SIAM Fellow. 

"Not only are Elizabeth's contributions technically outstanding, but her work also provides deep insights into the functioning of the heart and its abnormalities."

Cherry’s leadership and service extends outside of SIAM, influencing students and faculty across Georgia Tech. 

In December, the College of Computing appointed Cherry as associate dean for graduate education. Before this appointment, she served as associate chair for academic affairs of the School of CSE. 

With her new role as associate dean, Cherry continues serving as director of CSE programs at Georgia Tech. 

In March 2024, Cherry was among five Georgia Tech faculty members selected for the ACC Academic Leaders Network (ACC ALN) Fellows program. The ALN program fosters cross-institutional networking and collaboration between ACC schools, increasing each institution’s academic leadership capacity.

Cherry was part of a team of Georgia Tech and Emory University researchers who won a Georgia Clinical and Translational Science Alliance award in 2023. The group earned the Team Science Award of Distinction for Early Stage Research Teams award for work that captures high-resolution visualizations of spiral waves that create heart arrhythmias.

SIAM will recognize Cherry, Scheinberg, and Class of 2025 fellows during a reception at the SIAM/CAIMS Annual Meetings this July in Montréal.

“It is such an honor to be recognized as a SIAM Fellow,” Cherry said. “I’m thrilled to join my CSE colleagues who have also received this recognition.”

The College of Sciences has named Professor Joel Kostka the inaugural faculty director of Georgia Tech for Georgia's Tomorrow. The new center, announced by the College in December 2024, will drive research aimed at improving life across the state of Georgia. 

“Joel is perfectly suited to lead this new initiative, especially since his research for a number of years has focused on Georgia and the vulnerability of both humans and ecosystems to climate change,” says Susan Lozier, dean of the College of Sciences, Betsy Middleton and John Clark Sutherland Chair, and professor in the School of Earth and Atmospheric Sciences. “I look forward to seeing how Science for Georgia’s Tomorrow takes shape and evolves under his thoughtful leadership.”

“I believe that my experience in research administration and in leading multidisciplinary research programs, along with the focus of my research on the vulnerability of Georgia’s communities to climate change, have prepared me well for this role,” says Kostka, who is the Tom and Marie Patton Distinguished Professor and associate chair for Research in the School of Biological Sciences with a joint appointment in the School of Earth and Atmospheric Sciences. “I am excited about the opportunity to lead the center as its inaugural director.” 

Kostka’s appointment will begin on May 1, 2025. 

Championing science in Georgia

Georgia's Tomorrow was created to foster research related to the health and resilience of Georgia’s people, ecosystems, and communities. Specifically, it will serve to boost research collaboration across the Institute, pave the way for public-private partnerships, and expand opportunities for Georgia students and communities to engage with Institute research. 

Among Kostka’s first tasks as faculty director will be the development of the center’s strategic plan and the completion of two dedicated cluster hires from within the College of Sciences’ six schools. 

Meet Joel Kostka

Kostka is known for bridging biogeochemistry and microbiology to elucidate the role of microorganisms in ecosystem function. He has emerged as an international leader in ecosystem biogeoscience, providing a quantitative predictive understanding of how ecosystems function as well as determining the mechanisms by which climate change alters ecosystem resilience. He partners with a variety of stakeholders to conduct research on the restoration and adaptive management of coastal ecosystems in Georgia.

Kostka has also served as the PI of a range of multidisciplinary research projects focused on environmental change as well as scientific advisory boards including Georgia Tech’s Strategic Energy Institute, the NSF-funded Plum Island Estuary Long-term Ecological Research program, and the Johnston Center for Coastal Sustainability on Bald Head Island.

Kostka received a B.S. in Biology from Western Illinois University and a Ph.D. in Marine Science from the University of Delaware. Prior to joining Georgia Tech in 2011, he was a professor at the Department of Oceanography and Associate Director of the Institute of Energy Systems, Economics, and Sustainability at Florida State University.

Initial support for Georgia Tech for Georgia’s Tomorrow is generously provided by the College of Sciences Betsy Middleton and John Clark Sutherland Dean's Chair fund. Cluster hire funding has been awarded by Provost Steven W. McLaughlin. The initiative will also seek funding from state, national and international organizations, private foundations, and government agencies to expand impact. Philanthropic support will also be sought in the form of professorships, programmatic support for the center, and seed funding.

Georgia Tech for Georgia's Tomorrow initially launched under the working name Science for Georgia's Tomorrow (Sci4GT). 

Four students from Startup Lab have been selected to join the 2025 immersive cohort at South by Southwest (SXSW) in Austin, Texas. Alex Aridgides (mechanical engineering and economics), Shinhai Chen (industrial engineering), Varuni Chopra (industrial engineering), and Christie Peng (computer science) are the first Georgia Tech students to be invited to the program.

The weeklong, all-expenses-paid program offers university-affiliated innovators the chance to refine their innovations, engage in customer discovery, and network with industry leaders and peers at SXSW. The annual festival celebrates technology, film, music, education, and culture. Students participated in a competitive application process, which involved submitting applications, meeting specific evaluation criteria, and being selected by a panel of industry experts, mentors, and SXSW organizers.

Yolanda Payne, the students’ Startup Lab instructor, presented the SXSW opportunity in class.

"My goal is to be their biggest cheerleader,” she explained. “I had great teachers who helped me get to where I am today, and I strive to emulate their support. I’m always willing to guide students toward new opportunities."

She learned about the SXSW immersive cohort from Nakia Melecio, director of the National Science Foundation I-Corps Southeast Hub. The $15 million initiative crosses nine major research universities in the southern U.S. and accelerates the translation of deep tech research into commercial ventures. The hub works closely with entrepreneurial faculty, students, and researchers to equip them with the tools, networks, and support to bring their innovations to market.

Melecio plays a central role in identifying and advancing strategic opportunities for university partners and their entrepreneurial teams. “When the opportunity to participate in SXSW arose, I recognized it as an ideal platform to showcase the talent and innovation coming out of our region.”

Melecio added that Startup Lab is ideal for amplifying NSF I-Corps’ goals because of the course’s proven track record of fostering hands-on learning and commercialization readiness. “Startup Lab helps prepare students not just to think entrepreneurially, but to act on their ideas with confidence and a structured path forward. It was a natural fit for this opportunity.”

Payne says the experience students gained in Startup Lab helped prepare them for the immersive cohort. “The knowledge is being solidified by an experience you’re having in my class and the real world.”

Chopra agrees that Startup Lab teaches essential business development fundamentals and customer discovery principles, skills that are relevant to the SXSW program. She recommends the course to other students and emphasizes the value of combining engineering or technical backgrounds with entrepreneurship skills.

“We take a lot of classes that are directly related to our major, and they're very technical. But when it comes to wanting to start something of your own or even understanding how startups work, it's completely different than the rest of our coursework.”

Startup Lab is a three-credit course that focuses on evidence-based entrepreneurship. This hands-on class covers ideation, teamwork, customer discovery, minimum viable products, the business model canvas, and other topics. Students learn how to launch a startup by integrating in-class lectures with practical, out-of-class activities, including interviewing potential customers and refining their startup ideas based on real-world feedback. 

The program provides access to valuable resources, mentorship from seasoned entrepreneurs, and a supportive community to help students develop their startups. Startup Lab and NSF I-Corps are also exploring other industry showcases for student entrepreneurs like SXSW. 

Chen chose Startup Lab to pursue his entrepreneurial interests. “I knew that Georgia Tech had a really good startup culture, so I researched what they had to offer, and Startup Lab was the first step." He also noted Payne's impact as an instructor. "The best part is how much she cares about the topic. She has a lot of background knowledge and is passionate.”

Startup Lab is unique because it "de-risks the business model,” Payne says. Many entrepreneurs first build their products and then talk to potential customers. However, Startup Lab students perform customer discovery, sharing their ideas with potential end users, listening to their needs and feedback, and then building the product. 

Peng recalls a powerful moment of pitching an idea for an app to streamline MARTA operations. “I had a fun time coming up with this idea. We learned a lot about interviewing, coming up with possible solutions, and refining our idea,” she says. "Being surrounded by so many brilliant individuals at Georgia Tech makes it easy to get idea formation or networking connections you need for your idea to succeed."

Aridgides has ambitious post-program goals, envisioning creating change through entrepreneurship. "I want to start a company to change the world for the better and make a big impact. That's my life goal. I think through a company, I can achieve that."

Payne reminds students that they possess something many adults lack: time to explore different ideas. She also says Startup Lab can help students value and see their ideas in new ways. 

“They don't recognize that the product they're working on could be pursued through entrepreneurship or think of themselves as entrepreneurs. And even if they don't pursue it, it helps them in all aspects of life because business and capitalism are part of what we do every day.”

If you’re a student interested in adding entrepreneurship to your course schedule, registration for the summer and fall semesters opens on April 15. In addition to Startup Lab, students also have the opportunity to build a prototype with support through Idea to Prototype and CREATE-X Capstone Design.

Peter Yunker boils down his advice for researchers wanting to commercialize their lab advances. 

“You can’t go it alone,” said Yunker, an associate professor of physics at Georgia Tech. 

In January, Yunker co-founded the biotechnology startup TopoDx LLC, with David Weiss, an Emory University School of Medicine researcher and director of the Emory Antibiotic Resistance Center, and Yogi Patel, a Georgia Tech alumnus with a background in business development and bioengineering. 

“Researchers often think that they have a good commercialization idea to help people, but that alone does not guarantee success,” said Yunker. “Look for partners with complementary skills who understand aspects of the commercialization process that you don’t. Find mentors with business and scientific backgrounds in the specific industry you want to enter.”

TopoDx has developed a microbial test to identify antibiotic resistance and susceptibility rapidly and accurately. Current tests produce a result in three to five days. TopoDx’s approach can gain a result within four hours. Every hour counts in treating serious infections. Delays in accurate treatment can increase antibiotic resistance, which is a global challenge, causing up to 1 million deaths a year. 

The company’s testing method was inspired by a fundamental biophysics project in Yunker’s lab. His team was interested in understanding how bacterial colonies behave. They tested white-light interferometry, a technology that can measure bacterial colonies down to the nanometer level. 

“White-light interferometry allowed us to identify changes in the topography of a colony that indicated larger changes in the volume of cells in the entire colony,” said Yunker. “We thought this might have practical applications.” 

The next step was giving research talks at meetings and looking for collaborators. “I wanted to find someone with expertise on the bacteriology side, and I was very fortunate to meet David Weiss,” Yunker said, noting his proficiency in heteroresistance, a phenomenon where a small subset of a bacterial colony resists an antibiotic. 

“If you have just one antibiotic-resistant cell in a hundred cells, it can cause treatments to fail,” said Yunker. 

The two collaborators hoped to commercialize their technology, identifying heteroresistance in microbial samples. However, they needed guidance in creating a business model. They consulted Harold Solomon, an entrepreneur with Georgia Tech VentureLab and a principal in the Quadrant-i program, a specialized program helping Georgia Tech faculty and students commercialize research.  

Solomon became a key mentor. He guided them away from an ill-advised partnership and instead introduced them to Yogi Patel, who became a co-founder and the company CEO. 

This new collaboration provided the team with an important lesson — one that Yunker passes along to other researchers looking to commercialize their discoveries. “Seek expertise outside your field, be humble about your knowledge limitations, and view collaboration as a strategic partnership,” he says.

When Patel came on board, he conducted extensive interviews with more than 15 clinical professionals.

“You need to interview end users or purchasers of whatever solution you want to build,” said Patel. “Ask them if the problem you think you may have solved is a problem with scale, with a market need.” 

Clinicians, Patel learned, did not see heteroresistance as a significant issue. Instead, the slow pace of antibiotic testing was identified as a major problem. Faster testing could allow clinicians to prescribe targeted drugs more quickly and accurately, reducing unnecessary antibiotic use and the risk of multi-resistant infections. 

With this survey information, Patel asked Yunker and Weiss to rethink how their technology could be commercialized. 

“A company must solve a real-world problem,” said Patel. “I recommended that we switch from heteroresistance to solving slow antibiotic testing. We could keep heteroresistance as something we can still do as a second or third priority.” 

TopoDx’s new technology can measure, with single-nanometer accuracy, how bacterial colonies are responding to antibiotics in real time. This method could revolutionize how antibiotics are tested and prescribed. Testing would be conducted on a countertop device about the size of a large microwave. The co-founders envision the device as eventually being used by urgent care facilities and hospitals. 

“We want to make microbial testing susceptibility accessible anywhere and everywhere,” said Patel.   

Adam Krueger, once a Ph.D. student in Yunker's lab, has continued to refine the technology. Now a post-doctoral researcher, Krueger joined TopoDx in a technical leadership role to expand the technology’s capabilities for microbiological diagnostics.

“We will keep pushing the envelope forward scientifically while we try to commercialize the accomplishments that we have already made,” Yunker said. “We hope that some fundamental studies we are doing now out of scientific curiosity could lead to further commercial applications.”

Georgia Tech faculty members and graduate students, join the Quadrant-i Startup Launch Program to commercialize your research this summer: Over 12 weeks, you'll receive comprehensive support including guidance from experienced mentors, a $10,000 commercialization grant, and $150,000 worth of in-kind services. Showcase your innovation at Demo Day, where you'll have the opportunity to present to over 1,500 attendees, including industry leaders and investors. Apply today! Applications close April 11.

Successful test results of a new machine learning (ML) technique developed at Georgia Tech could help communities prepare for extreme weather and coastal flooding. The approach could also be applied to other models that predict how natural systems impact society. 

Ph.D. student Phillip Si and Assistant Professor Peng Chen developed Latent-EnSF, a technique that improves how ML models assimilate data to make predictions.

In experiments predicting medium-range weather forecasting and shallow water wave propagation, Latent-EnSF demonstrated higher accuracy, faster convergence, and greater efficiency than existing methods for sparse data assimilation.

“We are currently involved in an NSF-funded project aimed at providing real-time information on extreme flooding events in Pinellas County, Florida,” said Si, who studies computational science and engineering (CSE). 

“We're actively working on integrating Latent-EnSF into the system, which will facilitate accurate and synchronized modeling of natural disasters. This initiative aims to enhance community preparedness and safety measures in response to flooding risks.” 

Latent-EnSF outperformed three comparable models in assimilation speed, accuracy, and efficiency in shallow water wave propagation experiments. These tests show models can make better and faster predictions of coastal flood waves, tides, and tsunamis. 

In experiments on medium-range weather forecasting, Latent-EnSF surpassed the same three control models in accuracy, convergence, and time. Additionally, this test demonstrated Latent-EnSF's scalability compared to other methods.

These promising results support using ML models to simulate climate, weather, and other complex systems.

Traditionally, such studies require employment of large, energy-intensive supercomputers. However, advances like Latent-EnSF are making smaller, more efficient ML models feasible for these purposes.

The Georgia Tech team mentioned this comparison in its paper. It takes hours for the European Center for Medium-Range Weather Forecasts computer to run its simulations. Conversely, the ML model FourCastNet calculated the same forecast in seconds.

“Resolution, complexity, and data-diversity will continue to increase into the future,” said Chen, an assistant professor in the School of CSE. 

“To keep pace with this trend, we believe that ML models and ML-based data assimilation methods will become indispensable for studying large-scale complex systems.”

Data assimilation is the process by which models continuously ingest new, real-world data to update predictions. This data is often sparse, meaning it is limited, incomplete, or unevenly distributed over time. 

Latent-EnSF builds on the Ensemble Filter Scores (EnSF) model developed by Florida State University and Oak Ridge National Laboratory researchers. 

EnSF’s strength is that it assimilates data with many features and unpredictable relationships between data points. However, integrating sparse data leads to lost information and knowledge gaps in the model. Also, such large models may stop learning entirely from small amounts of sparse data.

The Georgia Tech researchers employ two variational autoencoders (VAEs) in Latent-EnSF to help ML models integrate and use real-world data. The VAEs encode sparse data and predictive models together in the same space to assimilate data more accurately and efficiently.

Integrating models with new methods, like Latent-EnSF, accelerates data assimilation. Producing accurate predictions more quickly during real-world crises could save lives and property for communities.

To share Latent-EnSF to the broader research community, Chen and Si presented their paper at the SIAM Conference on Computational Science and Engineering (CSE25). The Society of Industrial and Applied Mathematics (SIAM) organized CSE25, held March 3-7 in Fort Worth, Texas.

Chen was one of ten School of CSE faculty members who presented research at CSE25, representing one-third of the School’s faculty body. Latent-EnSF was one of 15 papers by School of CSE authors and one of 23 Georgia Tech papers presented at the conference.

The pair will also present Latent-EnSF at the upcoming International Conference on Learning Representations (ICLR 2025). Occurring April 24-28 in Singapore, ICLR is one of the world’s most prestigious conferences dedicated to artificial intelligence research.

“We hope to bring attention to experts and domain scientists the exciting area of ML-based data assimilation by presenting our paper,” Chen said. “Our work offers a new solution to address some of the key shortcomings in the area for broader applications.”

On April 21 at 5 p.m. in the Marcus Nanotechnology Building Atrium, dozens of teams will present prototypes at the Spring 2025 Idea to Prototype (I2P) Showcase. They will be vying for a chance to get a golden ticket in CREATE-X’s Startup Launch program, which gives participants $5,000 in optional seed funding and $150,000 in in-kind services like accounting and legal services, mentorship, and entrepreneurial education, among other benefits. 

The I2P course, where these students develop their prototypes, offers research credit for undergraduate students up to $500 in reimbursement for physical material expenses and faculty mentorship. It’s open three times a year, in the spring, summer, and fall. Both undergraduate and graduate students can take the course, and students can take it up two times. 

Convexity Electronics finished in second place at the Fall 2024 I2P Showcase. The company delivers smaller, faster, and more cost-effective circuit boards compared to traditional lithography-based methods. We delved into the team’s journey, challenges, and aspirations in this exclusive Q&A with one of its founders, Calla Scotch.

Q&A with Team Convexity's Calla Scotch

Team Members:

Anuj Pandey, Junior, Mechanical Engineering

Why did you pursue your startup?

It’s so complex. There are so many routes, and it's so new in terms of how many people are working on it. One day I woke up and couldn't stop thinking about it, then I couldn't sleep about it, and then I couldn't stop working on it. It was one of those things where I couldn't stop.

Traditionally, circuit boards — the stuff that's in your phones, computers, cameras, cars, everything — are made entirely subtractively. You have your block of material and cut away the stuff you don't want. It's a well-thought-out manufacturing process, but it's mostly very expensive and very slow. The materials and electronics manufacturing industry hasn't changed in about 30 years because it's been optimized as much as it can be. 

What is your goal with Convexity?

To take that subtractive process and, instead of doing that, build the same circuits additively. I'm working on 3D printing the insulative base material, then 3D printing the conductive material, then using an electrical process to take those conductive materials and convert them into copper. And then doing layer after layer after layer to make the same circuits that someone in a subtractive process would do.

If you have traditional manufacturing, it takes about two weeks to ship from China, and it takes about a week to make a lab. My goal would be to make them in about five hours and then courier them over the same day. You don't need a big serial manufacturing facility if someone needs 6,000 boards. You don't have 6,000 printers in one room; all your printers are connected to the cloud. You could even go from 2D electronics to three-dimensional electronics. We just want to make more, smaller, faster, and cheaper than traditional manufacturing.

What surprised you about I2P?
How much time it took out of my day and how much I didn't want to do as much homework anymore. It made me want to focus all of my time on this and on how many different avenues there were to do what I wanted to do. I probably went through 30 different iterations of completely different scientific topics. I think because of how many options there were and how crazy scientifically advanced each of them was, it is what keeps me going.

What was your favorite part about I2P?

I did I2P for two semesters, and the best thing about it is getting to work on your own project and your own research for class credit.

What was challenging about building your prototype over the semester?

Sifting through all the research and development that has gone into this field. Electronics manufacturing has been around for a long time, and there's a lot of research and patents to work through and build on. I feel like I spent half my time coming up with ideas and the other half building the physical printer.

 

What would you say to students who are interested in entrepreneurship?
I can't tell you how much I've learned just by doing. Outside of that, talk to people. Just go out and talk to people. Ask people questions. Have your problem and get their input and insight on it, because how we make smart decisions and make startups that people want is by asking people what they want.

Rahul Saxena, director of CREATE-X, encouraged students not to feel like they have to be 100% ready before applying.

“We have seen classroom projects and hackathon teams move on to build very successful startups, even though they weren't originally thinking about it,” he said. “Students should apply for Launch to explore the possibility of it with whatever project they are doing now. You never know what could come of it.”
