Flooding dominated the headlines of summer 2025. Atypical storms and rising rivers in the Texas Hill Country washed away an entire summer camp. Glacial snow melt, combined with flash river floods, caused hundreds of deaths in Pakistan. As the Atlantic hurricane season hits its peak, Americans wait to see if another storm may be as unexpectedly devastating as 2024’s Hurricane Helene. 

Flooding can be an existential threat, affecting everything from infrastructure to health. Georgia Tech researchers are developing solutions to monitor and forecast flooding, as well as restore ecosystems to prevent future flooding. These efforts support communities’ resilience in the face of climate change and keep the U.S. secure.

This fall, 20 Georgia Tech students published a peer-reviewed scientific paper — the culmination of work done during a semester-long laboratory course. During the semester, students analyzed genomes sequenced from marine samples collected in Key West, Florida — doing hands-on original bioinformatics research on par with graduate students and working with bioinformatics tools to explore drug discovery potential.

The course, BIOS 4590, is a research project lab for senior biology majors that provides an opportunity for professors to share their expertise with students in a hands-on environment. In his class, Associate Professor Vinayak (Vinny) Agarwal, who holds joint appointments in the School of Chemistry and Biochemistry and School of Biological Sciences, aimed to introduce undergraduates to advanced bioinformatics tools through applied research using new-to-science raw data. 

The resulting paper, “Phylogenomic Identification of a Highly Conserved Copper-Binding RiPP Biosynthetic Gene Cluster in Marine Microbulbifer Bacteria,” which was recently published in ACS Chemical Biology, involves the historically understudied genus of Microbulbifer, a type of bacteria often associated with sponges and corals. These microbial communities are rich sources of natural products, small biological molecules often associated with medicine and drug discovery. 

"This class, and the resulting research, is a testament to the transformative power of hands-on learning,” 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. “The success of this course — and the students’ remarkable achievement — reflects Georgia Tech's commitment to fostering curiosity, collaboration, and scientific rigor and to empowering the next generation of scientists and leaders."

Funded by Agarwal’s 2023 National Science Foundation CAREER grant and Camille and Henry Dreyfus Foundation Teacher-Scholar award, the class also received support from leadership in the College of Sciences, School of Biological Sciences, and School Chemistry and Biochemistry. The study’s lead author, graduate student Yifan (Grace) Tang, served as the class teaching assistant, and was funded in part by a Biochemistry and Biophysics Graduate Assistance in Areas of National Need fellowship. 

“The students in this class are working on important, novel work — this cohort worked with real genomic data that had never been sequenced before,” she says. “Typically, researchers might work with one or two genome sequences, but we provided students with 42 — this might be the first time anyone has looked at Microbulbifer at such a wide scope.” 

From classroom to publication

To prepare for the class, Tang worked alongside Laboratory Manager Alison Onstine, who manages the School of Biological Sciences teaching laboratory spaces, to sequence the Key West bacterial genomes.

“Our work in the Agarwal Lab is in natural product discovery. We focus on finding new pharmaceutical drugs through marine bacteria — but with a bioinformatics spin,” Tang explains. “We wanted to bring this type of experience to undergraduates, so we gave fully sequenced genomes to students and asked them to look for potential properties.” 

Throughout the class, students learned different techniques for analyzing bacterial genome sequences and extracting data with various tools — gaining both lab and computational skills through hands-on experiences, live demos, and troubleshooting sessions. 

“The highlight was showing students just how much we can learn about a bacterial genus, especially one that hasn’t been studied at this scale before,” Tang shares. “This is a growing field, so there are so many opportunities for students to make meaningful contributions while learning new skills.”

Empowering future students

For many students, it was their first time using these types of tools, but Agarwal says that it’s something they'll likely encounter in both industry and research. He sees this type of research experience as especially helpful for seniors, who are often deciding between entering the workforce or continuing their education.

“Bioinformatics is increasingly important for analyzing big data. Students need the ability to manipulate and understand data using computational tools, and this class plays an important role in familiarizing them with this process,” he shares. “Our goal is to demystify research and give students the confidence and tools for both graduate school and for the workforce after graduation.”

The class will be offered for a third time in Fall 2026. While the exact course of research hasn’t yet been decided, “we always aim for something new that can produce publication-quality research — students don’t repeat past year’s work,” Agarwal says. This recent cohort of students built on the success of 18 undergraduates who took the class in 2023, who also published a paper. “This course truly underscores Georgia Tech’s commitment to pioneering meaningful undergraduate experiences — no other peer institution I know of is exposing undergraduates to bioinformatics at this level.”

Students in machine learning and linear algebra courses this semester are learning from one of Georgia Tech’s most celebrated instructors.

Raphaël Pestourie has earned back-to-back selections to the Institute’s Course Instructor Opinion Survey (CIOS) honor roll, placing him among the top-ranked teachers for Fall 2024 and Spring 2025.

By returning to the classroom this semester to teach two more courses, Pestourie continues to leverage proven experience to mentor the next generation of researchers in his field.

“Students played a very important part in the survey process, and I thank them for making the classes great,” said Pestourie, an assistant professor in the School of Computational Science and Engineering (CSE).

“I'm incredibly grateful that students shared their feedback so that I could go the extra mile to not only apply my expertise to teach in ways that I think work, but transform my instruction to reach students in the most impactful way I can.”

CIOS honor rolls recognize instructors for outstanding teaching and educational impact, based on student feedback provided through end-of-course surveys. 

Student praise of Pestourie’s CSE 8803: Scientific Machine Learning class placed him on the Fall 2024 CIOS honor roll. He earned selection to the Spring 2025 honor roll for his instruction of CX 4230: Computer Simulation. 

CSE 8803 is a graduate-level, special topics class that Pestourie created around his field of expertise. Scientific machine learning involves merging two traditionally distinct fields: scientific computing and machine learning.

In scientific computing, researchers build and use models based on established physical laws. Machine learning differs in that it employs data-driven models to find patterns without prior assumptions. Combining the two fields opens new ways to analyze data and solve challenging problems in science and engineering.

Pestourie organized student-focused scientific machine learning symposiums in Fall 2023 and 2024. CSE 8803 students work on projects throughout the course and present their work at these symposiums. Pestourie will use the same approach this semester. 

Compared to CSE 8803, CX 4230 is an undergraduate course that teaches students how to create computer models of complex systems. A complex system has many interacting entities that influence each other’s behaviors and patterns. Disease spread in a human network is one example of a complex system. 

CX 4230 is a required course for computer science students studying the Modeling & Simulation thread. It is also an elective course in the Scientific and Engineering Computing minor.  

“I see 8803 as my educational baby. Being acknowledged for it with a CIOS honor roll felt great,” Pestourie said. 

“In a way, I'm prouder of CX 4230 because it was a large, undergraduate regular offering that I was teaching for the first time. The honor roll selection came almost as a surprise.”

To be eligible for the honor roll recognition, instructors must have a minimum CIOS response rate of 70%. Composite scores for three CIOS items are then used to rank instructors. Those items are:

• Instructor’s respect and concern for students
• Instructor’s level of enthusiasm about the course
• Instructor’s ability to stimulate interest in the subject matter

Georgia Tech’s Center for Teaching and Learning (CTL) and the Office of Academic Effectiveness present the CIOS Honor Rolls. CTL recognizes honor roll recipients at its Celebrating Teaching Day events, held annually in March.

CTL offers the Class of 1969 Teaching Fellowship, in which Pestourie participated in the 2024-2025 cohort. The program aims to broaden perspectives with insight into evidence-based best practices and exposure to new and innovative teaching methods.

The fellowship offers one-on-one consultations with a teaching and learning specialist. Cohorts meet weekly in the fall semester and monthly in the spring semester for instruction seminars. 

The fellowship facilitates peer observations where instructors visit other classrooms, exchange feedback, and learn effective techniques to try in their own classes.

“I'm very grateful for the Class of 1969 fellowship program and to Karen Franklin, who coordinates it,” Pestourie said. “The honor roll is not just a one-person award. Support from the Institute and other people in the program made it happen.”

Like in Fall 2023 and 2024, Pestourie is teaching CSE 8803: Scientific Machine Learning again this semester. Additionally, he teaches CSE 8801: Linear Algebra, Probability, and Statistics.

Linear algebra and applied probability are among the fundamental subjects in modern data science. Like his scientific machine learning class, Pestourie created CSE 8801. This semester marks the second time Pestourie is teaching the course since Fall 2024.

Pestourie designed CSE 8801 as a refresher course for newer graduate students. This addresses a point of need to help students get off to a good start at Georgia Tech. By offering guidance early in their graduate careers, Pestourie’s work in the classroom also aims to cultivate future collaborators and serve his academic community.

“I see teaching as our one shot at making a good first impression as a research field and a community,” he said. 

“I see my work as a teacher as training my future colleagues, and I see it as my duty to our community to do my best in attracting the best talent toward our research field.”

I returned from Climate Week NYC energized by what I witnessed: Georgia Tech faculty, students, and startups showcasing the breadth and depth of our climate innovation work on one of the world's biggest stages.

Climate Week NYC brings together more than 900 events, but what stood out wasn’t the scale — it was the substance. Across five New York Climate Exchange partner events, the Georgia Tech community demonstrated something essential. Georgia Tech bridges research and real-world impact where it matters most — in people’s lives.

At the Super South event, we flipped the script on where climate innovation happens and demonstrated the Southeast as a climate tech powerhouse. Too often, conversations about climate tech center on coastal hubs. But Georgia Tech-affiliated entrepreneurs Tarek Rakha (Lamarr.AI), Mya Love Griesbaum (Mycorrhiza Fashion), Joe Metzler (Metzev), Laura Stoy (Ph.D. ECE 2021, Rivalia Chemical), Charlie Cichetti (MGT 2004, Skema), Joseph Mooney (research engineer, School of Civil and Environmental Engineering, WattAir), Lewis Motion (MBA 2017, WEAV3D), and Ramtin Motahar (IE 2004, ECON 2004, M.S. AE 2017, Joulea) showed that the Southeast isn’t just participating in the clean energy transition — we’re leading it.

The Climate Tech Fellowship Showcase was personal. Seeing two Georgia Tech teams — Patricia Stathatou and Christos Athanasiou’s yeast-based water purification system, and Xiao Liu’s AI-powered wildfire management platform — selected for the inaugural cohort reminded me why partnerships like the New York Climate Exchange matter. These early-stage innovators need more than good ideas. They need networks, mentorship, and funding pathways. NYCE provides those connections.

From flooding to batteries, two symposia highlighted GT faculty doing research that matters. At Weathering the Future, Iris Tien joined experts from AECOM, NVIDIA, and the NYC Department of Environmental Protection to discuss integrating resilience into urban infrastructure. Her work on coastal adaptation and infrastructure resilience addresses real vulnerabilities that cities face today. The Global Battery Alliance Leadership Meeting and Urban Battery Forum brought Yuanzhi Tang into conversations about building sustainable, circular battery value chains. As EVs scale and stationary storage grows, how we manage battery lifecycles — from securing raw resources to manufacturing to second-life reuse/recycling — will determine how we balance electrification, sustainability, environmental considerations, and economics; more details can be found in the NYCE report on battery circularity co-authored by Wyatt Williams (M.S. CEE 2024, MBA 2024).

Nicole Kennard’s leadership in the Climate Storytelling Workshop reinforced something I believe deeply: Technical solutions alone won’t solve the climate crisis. We need approaches that center community voices, acknowledge environmental justice concerns, and build trust. This became particularly clear in Kennard’s lecture for NYU’s Center for Urban Science and Progress: "Food, Place, and Belonging: From Global Visions to Local Sustainability." Presented with Janelle Wright (M CP 2022) from the West Atlanta Watershed Alliance, this lecture demonstrated how sustainable food systems can draw on global frameworks but must center community values and honor the history of place.

A few insights emerged from the week:

1. Geography matters — and so does bridging it. Collaborative platforms like NYCE that create genuine partnerships across regions will be more effective in achieving Georgia Tech’s vision of doing climate work that is grounded in Georgia and global in impact.

2. Visibility accelerates impact. Several faculty and entrepreneurs told me that Climate Week NYC opened doors — to investors, to funders, to partners, and to media. Platforms like NYCE amplify work that might otherwise stay local.

3. Students are passionate about climate opportunities. Every conversation about internships, fellowships, and experiential learning generated immediate interest. We need to build more pathways for students like Rohan Datta and Amanda Ehrenhalt to engage in climate work across both New York and Atlanta ecosystems — creating opportunities for hands-on experience, knowledge diffusion across regions, and the professional networks that will define their careers.

4. Our community extends far beyond campus. Meeting alumnus Alan Warren (PHYS 1978) drove this message home. Alan brings a unique vantage point on coastal resilience challenges faced in New York — and he’s energized by what our partnership can achieve. His offer to serve as Georgia Tech’s “envoy” in NYC, connecting our climate work to networks and opportunities there, is exactly the kind of volunteer leadership that accelerates impact. Alan’s own inspirational story of resilience and regeneration makes his commitment to climate resilience work even more meaningful.

Looking ahead, I see Georgia Tech’s partnership with the NYCE creating a powerful platform: NYCE amplifies our work through capital and convening; Georgia Tech anchors deployment with Southeast roots and global reach. Working alongside a distinguished board led by incoming chair Andrea Goldsmith, president of Stony Brook University, gives me confidence in this direction.

President Ángel Cabrera met with Goldsmith this week and reaffirmed our shared vision for bridging research and impact. “Georgia Tech’s mission has always been about translating knowledge into progress that serves society,” said Cabrera. “The New York Climate Exchange partnership exemplifies this commitment to innovative solutions that can be scaled to create real human impact. By connecting our strengths in community-engaged climate research with networks that can amplify and accelerate solutions, we’re living our motto of Progress and Service as we address one of humanity’s most urgent challenges.”

The Brook Byers Institute for Sustainable Systems (BBISS) convenes faculty, students, and partners to address sustainability challenges through research, education, and collaboration. Connect with BBISS on LinkedIn to be part of the ongoing discussion and/or reach out to Susan Ryan (susan.ryan@gatech.edu) to be added to BBISS’ climate science and solutions community of practice.

One of Georgia Tech’s newest undergraduate degree offerings — a B.S. in Astrophysics — welcomed its first students in August. 

The astrophysics program, which includes both a major and a minor, introduces students to the fundamental physical processes and laws that govern the cosmos. This foundational curriculum is complemented by training in computational and data analysis techniques.

“Our new undergraduate program is forward-facing, focusing on the future of astronomy and astrophysics as well as how big data and computing are driving innovation and discovery,” says Program Director David Ballantyne, associate chair for Academic Programs and professor in the School of Physics. 

Designed for students interested in research or non-research career paths, the B.S. in Astrophysics was created in response to growing student demand for courses and research opportunities in the field. 

“Astrophysics is a great major at Georgia Tech because it teaches the critical thinking and technical skills students need not just for astrophysics but also for a wide variety of STEM-related careers,” adds Paul Sell, program advisor, senior academic professional in the School of Physics, and director of the Georgia Tech Observatory.

More than two dozen students have already declared the astrophysics major or minor; these numbers are expected to grow as more students learn about the program.  

Third-year student Ishita Chintala switched her major from general physics to astrophysics in order to move closer to her childhood dream of working in the space industry.

“Astrophysics brings a certain kind of magic into my life; a kind of magic that helps me not only understand the world around me, but also helps me understand my place in the universe,” she explains. 

Students enrolled in the program will have the opportunity to engage directly with the work taking place at the Center for Relativistic Astrophysics (CRA). Established in 2008, the CRA includes more than a dozen faculty and research scientists with expertise spanning high-energy astrophysics, extrasolar planets, gravitational-wave astronomy, and astroparticle physics.

Access to undergraduate research opportunities, including those offered by CRA faculty, is one reason for Marshall Honaker’s enthusiasm about the major. 

“I’m most excited about getting hands-on research experience and taking advanced astrophysics classes that dive deeper into topics like cosmology and stellar evolution, especially at Georgia Tech,” says Honaker, a first-year student from Warner Robins, Georgia. He aims to pursue a research career to increase our understanding of the universe.

Andrew Heller, a first-year student from Tucker, Georgia, chose the astrophysics major because of his curiosity about and desire to advance our knowledge of everything beyond Planet Earth. 

“As an astrophysics major, I'm very interested in participating in multi-messenger astronomy,” says Heller, referring to a key research focus of the CRA. “The ability to discover different things about an event or object by studying it with different wavelengths or particles is super exciting!”

Undergraduate students interested in declaring the astrophysics major or minor should follow the standard major change or the minor addition/change process.

Georgia Tech’s Jaden Wang (Zhuochen Wang) has been awarded a NASA Space Technology Graduate Research Opportunity (NSTGRO). The grant supports graduate students who “show significant potential to contribute to NASA’s goal of creating innovative new space technologies for our nation’s science, exploration, and economic future.”

Wang, who is a Ph.D. student in the School of Mathematics and a master’s student in the Daniel Guggenheim School of Aerospace Engineering, will focus on developing mathematically-backed landing solutions for spacecraft. 

“I first became interested in powered descent problems during my Fall 2024 internship with NASA’s Human Landing System at Marshall Space Flight Center,” he says. “With my mathematical background in optimization and topology, and my passion for space exploration, I saw this research topic as a perfect fit when my co-advisor Dr. Panagiotis Tsiotras suggested it.”

Wang is co-advised by School of Mathematics Professor and Hubbard Research Fellow John Etnyre alongside Panagiotis Tsiotras, who holds the David and Andrew Lewis Endowed Chair in the Daniel Guggenheim School of Aerospace Engineering and is also associate director at the Institute for Robotics and Intelligent Machines.

In addition to his Georgia Tech advisors, Wang will collaborate with a NASA Subject Matter Expert, who will connect him with the larger technical community. He will perform part of the research as a visiting technologist at multiple NASA centers, giving him the opportunity to work with leading engineers and scientists and share his research results directly with the NASA community.

From abstractions to space exploration

“NASA’s upcoming missions to the Moon, Mars, and beyond need technology that allows spacecraft to land precisely at their intended sites,” says Wang. “My research will focus on the last stage of landing, called powered descent. This stage powers up engines, which guide the spacecraft into a safe landing using a pre-designed trajectory that autopilot follows.”

This means that researchers need to figure out the correct thrust, direction, and timing to reach a landing spot — all while navigating a landing that uses as little fuel as possible.

“A common approach is to treat this as an optimization problem: minimizing fuel consumption with rigid-body physics as constraints to determine the best thrust profile,” Wang explains. “This can work well, but it has drawbacks. It assumes that there is no uncertainty in the system (for example, that the thrust of the engines is applied perfectly) and it simplifies the motion of the spacecraft by treating it as though it’s traveling through flat space instead of on a true curved geometry. Both shortcuts introduce errors  — our research aims to address these gaps.”

To improve landing precision, Wang will develop a curved-space geometric mathematical model, which takes into account the curved-space geometry of spacecraft motion rather than assuming flat space. To find a fuel-efficient landing trajectory, Wang will develop the model around optimal covariance steering, a stochastic control problem that both minimizes fuel costs while keeping the uncertainty of the spacecraft's exact landing spot within a safe amount.

It’s a problem that leverages his experience in theoretical math and his background in aerospace engineering. “I’m incredibly honored that NASA finds this research exciting and is supporting my pursuit of it,” he says. “There are so many fascinating engineering problems that could benefit from deeper theoretical scrutiny, especially using abstract machineries not typically covered in an engineering curriculum. I hope this inspires more theoretical researchers and graduate students to explore bridging these gaps.”

Between a third and half of all soil carbon on Earth is stored in peatlands, says Tom and Marie Patton Distinguished Professor Joel Kostka. These wetlands — formed from layers and layers of decaying plant matter — span from the Arctic to the tropics, supporting biodiversity and regulating global climate.

“Peatlands are essential carbon stores, but as temperatures warm, this carbon is in danger of being released as carbon dioxide and methane,” says Kostka, who is also the associate chair for Research in the School of Biological Sciences and the director of Georgia Tech for Georgia’s Tomorrow. Understanding the ratio of carbon dioxide to methane is critical, he adds, because while both are greenhouse gasses, methane is significantly more potent.

Kostka is the corresponding author of a new study unearthing how and why peatlands are producing carbon dioxide and methane. 

The research, “Northern peatland microbial communities exhibit resistance to warming and acquire electron acceptors from soil organic matter,” was published this summer in Nature Communications, and was led by co-first authors Borja Aldeguer-Riquelme, a postdoctoral research associate in the Environmental Microbial Genomics Laboratory, and Katherine Duchesneau, a Ph.D. student in the School of Biological Sciences.

The study builds on a decade of research at the Oak Ridge National Lab’s Spruce and Peatland Responses Under Changing Environments (SPRUCE) experiment, a long-term research project in Minnesota that allows researchers to warm whole sections of wetland from tree top to bog bottom.

“Over the past 10 years, we’ve shown that warming in this large-scale climate experiment increases greenhouse gas production,” Kostka says. “But while warming makes the bog produce more methane, we still observe a lot more CO2 production than methane. In this paper, we take a critical step towards discovering why — and describing the mechanisms that determine which gases are released and in what amounts.”

Methane mystery

The subdued methane production in peatlands has been a long-standing mystery. In water-saturated wetlands, oxygen is scarce, but microbes still need to respire — a type of ‘breathing’ that allows them to produce energy for metabolic function. Without oxygen, microbes use nitrate, sulfate, or metals to respire — still releasing carbon dioxide in the process. However, if these ingredients aren’t present, microbes ‘breathe’ in a way that releases methane.

Since nitrate, sulfate, and metals are relatively rare in peatlands, methane production should be the most likely pathway, but surprisingly, observations show the opposite. “In both fieldwork and lab experiments, peatlands produce much more carbon dioxide than methane,” Kostka explains. “It’s puzzling because the soil conditions should help methane production dominate.”

To solve this mystery, the team leveraged a suite of cutting-edge genetic tools called “omics” —  metagenomics (studying DNA), metatranscriptomics (studying RNA), and metabolomics (a technique used to study the “leftovers” of metabolism), providing a detailed look under the hood of the microbial “engine” that cycles organic matter in wetlands. It also gave a new window into the diversity of soil microbes in wetlands: 80 percent of the organisms identified in the study were new at the genus level.

‘Omics’ innovations

Over the course of several years, the team collected samples from a peatland enclosed in an experimental chamber that was slowly warmed, then analyzed the samples using omics to see how they changed. Initially, they hypothesized that warming the soil would cause microbial communities to change quickly. “Microbes can evolve and grow rapidly,” Kostka says. “But that didn’t happen.”

The DNA-based methods showed that while the microbial communities stayed largely stable, the bog did release more greenhouse gasses as it warmed. To assess the metabolic potential of the microbes, Duchesneau and Aldeguer-Riquelme constructed microbial genomes, investigating how they were decomposing the organic matter in peatlands and cycling carbon.

“We found that microbial activity increases with warming, but the growth response of microbial communities lags behind these changes in physiological or metabolic activity,” Kostka says. He cautions that this doesn’t necessarily mean that wetland communities won’t change as climates warm — just that these shifts might come behind metabolic ones. 

A diversity of discoveries

And the methane? The team believes that microbes may be breaking down organic matter to access the key ingredients for producing carbon dioxide — nitrate, sulfate, and metals — though more research is currently underway to investigate this.

“Doing this type of integrated omics research in soil systems is still incredibly difficult,” Kostka says. The challenge is multifaceted: the research leverages years of experiments, long-term datasets, advanced laboratory techniques, and fieldwork innovations. 

At SPRUCE, experimental chambers are about 1,000 square feet. While it’s an impressive experimental setup, researchers still must be careful: “We need to take soil samples for many years, so if we take too many, there’d be no soil left!” Kostka explains. “Part of our research involves developing better, non-destructive sampling techniques.”

The other challenge lies in what makes these peatlands so unique: it’s very hard to detect small changes because of the sheer diversity of organisms present. “Every time we conduct this type of research, we learn more about these incredible systems,” he says. “There’s always something new.”

J. Cole Faggert, a Ph.D. student in the School of Physics, has received a NASA FINESST (Future Investigators in NASA Earth and Space Science and Technology) Award to study supermassive black holes and the physics of their plasma flows. His research proposal was one of 24 selected from more than 450 astrophysics submissions this year. 

“It’s amazing to be recognized for this research,” says Faggert. “I am grateful to my research group for helping me prepare the proposal and inspiring my ideas.”

Through the FINESST program, NASA’s Science Mission Directorate provides three-year grants for “graduate student-designed and performed research projects that contribute to its science, technology, and exploration goals,” according to the program’s website. 

Faggert will serve as the future investigator of the award and will be advised by Feryal Özel, chair and professor in the School of Physics. 

“I am very proud that Cole has been selected for the FINESST Fellowship, one of the most competitive graduate awards in the country,” says Özel, who is the principal investigator of the research. “This fellowship will support groundbreaking research on multi-wavelength imaging of black holes — an area central to advancing our understanding of black holes and galaxies. It is especially exciting that this work also contributes directly to the development of our space-based mission at Georgia Tech.”

A key aspect of Faggert’s proposal is its multi-frequency approach, which generates and analyzes images of supermassive black holes using different radio wavelengths. When combined and compared, these multi-frequency observations allow scientists to learn about black holes and explore fundamental physical concepts such as gravity and plasma behavior.

“One of the coolest things about studying cosmic objects like black holes is that you have to work with the information you have,” explains Faggert. “But when you combine several avenues of information, like in multi-frequency radio imaging, you can gain a better understanding of phenomena and under conditions that can’t be replicated on Earth.”

This research aligns with current trends in astrophysics that focus on advanced imaging techniques to broaden the data available on the structure, formation, and behavior of black holes and other celestial objects. According to Faggert, this information can then be contrasted with theoretical simulations, providing insights into fundamental physics and the nature of the universe.

Receiving the FINESST Award is particularly meaningful for Faggert, given his longstanding interest in space and his previous exposure to NASA’s Wallops Flight Facility and Langley Research Center through the Virginia Aerospace Science and Technology Scholars program.

“Being associated with NASA holds a special place in my heart. Over the years, my focus has shifted from designing space missions to studying the science those missions make possible. It is definitely rewarding to come full circle and be recognized by NASA for this research,” he adds.

What does the future look like? On Aug. 28, from 5 – 7 p.m., more than 1,500 attendees will gather at Georgia Tech’s Exhibition Hall to find out at Demo Day, where CREATE-X will showcase over 100 startups coming out of Georgia Tech. Tickets are free but limited — early registration is strongly encouraged. 

At Demo Day, founders bring solutions that tackle some of today’s most urgent challenges across industries. Expect to see startups tackling global challenges with bold new solutions, such as: providing mRNA therapies that could transform vaccine access, using ultra-efficient AI chips that run on a fraction of the power, and building innovative inspection tools that are already helping companies like Tesla catch defects in seconds. Demo Day provides attendees an opportunity to gain hands-on experience with new products, meet the founders behind them, and experience the momentum of a startup ecosystem in full swing.

Donnie Beamer, the City of Atlanta’s senior technology advisor, attended the last Demo Day and spoke about moments that impressed him most.

“The founders of NeuroChamp had a headband that reads brainwaves. It makes me call into question what I was doing in college!” Beamer said.

Founders showcasing at Demo Day have spent 12 weeks working on their startups during the CREATE-X accelerator, Startup Launch.

“Every founder in that room will have spent the summer chasing the right problem and building a solution to solve it,” Rahul Saxena, director of CREATE-X, said. “Demo Day is proof that entrepreneurship can be taught and developed, from ideation to customer discovery.”

Beamer said that the program pushes people to be creative.

 “Georgia Tech is a safe place to try and fail and innovate, which is invaluable. Instead of just telling students to do X and expecting them to execute on it, CREATE-X allows for creativity and discovery,” Beamer said. “That can be transformative for students, the Institute, and the city of Atlanta.” 

Unlike other startup exhibitions, there are no on-stage pitches — just direct connection in a casual, interactive format. Attendees and investors can test the tech out themselves. Past Demo Days have led to venture funding, strategic partnerships, media coverage, and more. It’s an energetic atmosphere with the exchange of ideas, an opening of doors, and a community building the future together. 

“There are a few kinds of naysayers; for example, some who think Atlanta doesn’t have much entrepreneurial activity and others who feel isolated from communities like this one,” Beamer said. “Demo Day lets them look behind the curtain and see the vibrant, innovative ecosystem that they can be a part of in our city as we look to become a top-five tech hub in the nation. Georgia Tech is a huge part of that.” 

Register for Demo Day today! The future is waiting for you to discover it.
