As drones, air taxis and emergency aircraft begin to fill city skies, the biggest challenge may be invisible: how radio signals move through dense urban environments.

That future depends on reliable communication systems that can function reliably amid buildings, materials and interference, a problem UCF postdoctoral researcher Saumya Gupta is working to solve.

“Collaborating with NASA through the MUREP MPLAN program provides an opportunity to contribute to cutting-edge research that supports the future of aviation and air mobility.” — Saumya Gupta, postdoctoral researcher

Gupta received a NASA Minority University Research and Education Project (MUREP) Partnership Learning Annual Notification (MPLAN) award to study and model how radio signals behavior in complex urban environments. She is working with co-principal investigator , an associate professor in UCF’s , on a project titled “A Digital Twin for AAM Communication Channels.”

Gupta’s research focuses on urban air mobility, where drones, emergency response aircraft and potential air taxis depend on reliable communication networks to operate safely in dense cities. The work builds on a growing body of AAM research at UCF, including prior simulation efforts led by Professor Vela, by focusing specifically on how communication signals move through crowded cities.

“Collaborating with NASA through the MUREP MPLAN program provides an opportunity to contribute to cutting-edge research that supports the future of aviation and air mobility,” Gupta says. “It allows our team at UCF to work on problems that are directly relevant to NASA’s AAM (advanced air mobility) mission while also benefitting from guidance and collaboration with NASA researchers. This partnership helps ensure that our research addresses real-world challenges in integrating new air vehicles into the national airspace.”

Building the Digital Twin

Traditional radio frequency prediction models often rely on simplified formulas that estimate how signals weaken over distance. While useful, these models lack the spatial and material detail needed to represent dense urban environments where glass, steel and concrete significantly affect signal behavior.

More advanced simulation tools can model signal reflection, absorption and diffraction using digital maps. Most maps include building shapes but not detailed material data, a factor that strongly influences how signals are transmitted.

To address this limitation, Dr.Gupta and Professor Vela, along with their research team, are developing a simulation-based digital twin, a virtual model of an urban communication environment that incorporates artificial intelligence to improve prediction accuracy.

“Reliable communication is essential for future systems such as drones, emergency response UAVs and urban air taxis.” — Saumya Gupta, postdoctoral researcher

Rather than relying solely on static maps, the system trains neural networks using signal data collected by uncrewed aerial vehicles. By analyzing how signal strength changes across locations, the system can infer building material properties and refine the model accordingly. Over time, this approach allows the digital twin to become more adaptive and better aligned with real-world conditions.

“Reliable communication is essential for future systems such as drones, emergency response UAVs and urban air taxis,” Gupta says. “By using a digital twin to model how buildings and materials affect radio frequency signals, this research helps identify where signals may weaken, become blocked or experience interference. These insights can guide safer routing, real-time coordination and the scalable airspace management that future urban air mobility will depend on.”

Strengthening Industry-Academic Partnerships

NASA’s MUREP program aims to broaden participation in aerospace research while strengthening partnerships between universities and NASA centers.

Through the MPLAN initiative, faculty researchers work directly with NASA scientists to develop technologies aligned with the agency’s long-term missions while also expanding opportunities for students to engage in aerospace research.

“We plan to expand student involvement as the project progresses,” Gupta says. “We also look forward to engaging with NASA researchers to provide mentorship and collaborative learning opportunities.”

In addition to Gupta’s project, UCF researcher Justin Urso also received a MUREP MPLAN award supporting research on communication and sensing systems for advanced air mobility, further reflecting UCF’s role in NASA’s urban initiatives. Urso is a research assistant professor of mechanical and aerospace engineering who conducts work in Professor Subith Vasu’s laboratory.

Four outstanding undergraduate students are redefining the boundaries of STEM through their high-impact research — and in doing so, placing the university among the nation’s top producers of Goldwater Scholars.

The prestigious Goldwater Scholarship identifies and supports the nation’s best student researchers in the fields of engineering, mathematics and natural sciences.

This year’s honorees — all expected to graduate next spring — have propelled UCF into an elite tier of research institutions, surpassing several Ivy League institutions and tying for fourth in the nation in total Goldwater Scholars produced alongside Stanford University, the University of Notre Dame and the University of Chicago. Their impactful work reflects UCF’s commitment to building a high-level research environment that empowers students to lead projects addressing significant global and scientific challenges.

Supporting Space Exploration

Goldwater Scholar: Keanu Brayman

Major: Mechanical engineering

Ultimate Goal: To develop robotic systems to support human exploration on Mars.

Keanu Brayman’s passion for space began early.

“One of my earliest memories is watching a Space Shuttle streak across the sky from a beach in South Florida,” Brayman says. “I remember being amazed there were people on board and feeling drawn to one day help explore the stars and discover what lies beyond our planet.”

ɫ����, Brayman has refined that dream with the support of faculty and mentors — including Associate Professors Adrienne Dove (physics) and Tarek Elgohary (mechanical and aerospace engineering), and NASA Marshall Space Flight Center Engineer Christopher Proctor — as well as through programs like the .

He plans to pursue a doctoral degree in aerospace engineering to support lunar exploration and NASA’s Artemis program, as well as develop robotic systems that can extract resources and build infrastructure to support human exploration on Mars.

Engineering the Brain

Goldwater Scholar: Kyle Coutray

Majors: Computer engineering and biomedical sciences

Ultimate Goal: To research ways to restore communication, movement and cognitive function to the brain through engineering methods.

Kyle Coutray is focused on the intersection of neuroscience and technology.

“I’m interested in building systems that interact directly with the brain,” Coutray says. “In the lab, … [I’m] blending [both majors] into one approach.”

He aims to pursue a doctoral degree in neural engineering to further his research on brain-computer interfaces that translate complex brain activity into useful functions.

A 2026 Order of Pegasus inductee and a Burnett Honors Scholar, Coutray credits his success to disciplined focus and strong mentorship, particularly from Charles N. Millican Professor of Computer Science Joseph LaViola and Associate Professor of Mechanical and Aerospace Engineering Helen Huang.

Advancing Patient Care

Goldwater Scholar: Varun Nannuri

Major: Molecular and cellular biology

Ultimate Goal: To pursue a career as a physician-scientist.

Varun Nannuri is driven by a desire to understand why people experience different health outcomes and improve care.

“Through my clinical experiences, I have seen how much patients and families rely on physicians during some of the most difficult moments of their lives,” Nannuri says. “My research experiences have shown me that better care depends on asking better questions.”

Nannuri plans to pursue a dual M.D./Ph.D. degree and become a physician-scientist. His ambition earned him recognition as a 2026 Order of Pegasus inductee while also completing his Honors Undergraduate Thesis. Nannuri is also a member of the Burnett Honors College as a Burnett Medical Scholar, a program that offers guaranteed admission to the UCF College of Medicine upon completion.

“UCF has given me opportunities to grow as a student, researcher, leader and future physician,” Nannuri says.

Restoring Human Senses

Goldwater Scholar: Trevor Overton

Majors: Electrical engineering and biomedical sciences

Ultimate Goal: To improve the lives of people with disabilities through advanced robotic prostheses.

Burnett Honors Scholar Trevor Overton’s work centers on neuroengineering and next-generation prosthetics.

“I’ve always had a passion for building things, and I also love reading and watching sci-fi,” Overton says. “When UCF offered me the opportunity to join the MEDD [ … I knew I had to take it.”

UCF’s MEDD program provides scientifically driven students like Overton with a unique opportunity to integrate engineering principles into medicine.

Much like the development of cochlear implants, Overton imagines similar breakthroughs with vision and touch.

“I envision a future where robotic prostheses are so advanced that they could completely replace or enhance the abilities of humans,” Overton says. “It’s not entirely impossible.”

After earning a doctoral degree in electrical engineering with a focus on neuroengineering, he hopes to inspire the next generation — just as his professors inspired him — emphasizing that UCF’s strength lies in professors who actively invest in their students.

A Growing Research Powerhouse

With four 2026 Goldwater Scholarship recipients, UCF continues to strengthen its position as a leader in undergraduate research. The achievement reflects both students’ immense dedication and a university-wide commitment to driving innovation, mentorship and hands-on discovery. As these Knights prepare for the next steps in their academic journeys, they carry forward a shared mission: to turn research into real-world impact.

To better understand Assistant Professor Hamzeh Ghasemzadeh and his work, he goes back to a childhood memory of broken toys. Within hours of receiving little robotic figures or remote-control cars, he’d dissembled what had once been a carefully crafted package of technology. To him, sitting among the remnants of a new gift meant he was sitting in a circle of fun.

“My favorite game was to take the toys apart to see how they work and then try to put them back together,” Ghasemzadeh says. “My parents saw my curiosity as a great thing.”

“This is why I came to UCF. I’ve been able to jump right in and address mysteries that haven’t received much attention.”

That same curiosity now drives his research at , where he seeks to take apart discomforted voices, figuratively, so he can develop strategies to make each one whole again. Ghasemzadeh, who joined UCF in late Summer 2025 and will teach in the school’s newly launched , has already secured one research project funded by the U.S. National Institutes of Health and is developing another.

“This is why I came to UCF,” he says. “I’ve been able to jump right in and address mysteries that haven’t received much attention until now.”

A Common Problem Without Clear Answers

The first such mystery sounds quite straightforward: vocal fatigue, a common vocal complaint. Beneath the surface, however, it’s deceptive. Solutions have mostly evaded scientists, leaving vocal fatigue as an ongoing problem for many people who rely on their voices, like coaches, public speakers, singers and teachers. Many of Ghasemzadeh’s colleagues experience the very throat discomfort that he’s deconstructing during the funded project just underway.

“We want to collect … multi-modal data and use machine learning models to analyze [vocal fatigue] and develop recommendations for each person.”

“Some instructors get vocal fatigue quickly, some get it slowly and some don’t get it at all,” he says. “There’s a genetic component, but there are also behavioral components. How do they use their voice? How often do they use it? What about the environment where they’re using it? What about personality? We want to collect such comprehensive multi-modal data and use machine learning models to analyze it and develop recommendations for each person.”

The recommendations might include pacing voice usage, projecting the voice efficiently and allowing the voice to recover. Ghasemzadeh envisions this model being predictive and — this is the part he stresses most — personalized.

“The approach to general medicine started with an assumption that while we’re different on the outside, we are very similar inside. Patients with similar ailments took the same medications and [the] same dosages. But we now know that people don’t always respond to pills the same way. If we can quantify how we’re different inside, we can create a computational model to predict responses to medications and optimize treatment plans.”

To integrate artificial intelligence (AI) into vocal fatigue solutions, subjects in Ghasemzadeh’s study will wear sensors that track how and where they use their voices. He’ll prompt them to perform specific vocal tasks and monitor their phonatory function throughout the day. The AI model will analyze these patterns in real time to identify early signs of vocal strain and predict when fatigue is likely to occur.

“We are different. Every prescribed solution should be different, too.”

Participants will also visit his lab at the in Central Florida Research Park, where specialists will collect imaging, aerodynamic and acoustic data. The highly equipped facility brings together America’s leading hearing and voice scientists to develop new technologies and clinical tools for people with hearing loss or voice disorders.

With all of that in hand, including the technology, Ghasemzadeh and his team hope to unwind the mystery of vocal fatigue — one person at a time.

“That’s the idea I want to put forward with every project,” he says. “We are different. Every prescribed solution should be different, too.”

From Engineering to Human Connection

Many would think a toy-reassembling boy is destined to become an engineer. That’s what Ghasemzadeh thought, too. He earned bachelor’s and master’s degrees in electrical engineering and began his career with a focus on telecommunications and signal processing.

“There was something important missing,” he says. “Human connection.”

“Speech became my research interest because … it sets us apart as a species and as individuals.”

He crossed paths with a close friend who mentioned his own research in a field Ghasemzadeh was vaguely familiar with: communication sciences and disorders. The conversation sparked Ghasemzadeh’s enthusiasm for applying his expertise in areas such as signal processing to personally help others.

“Speech became my research interest because it’s the signal we predominantly use to communicate,” he says. “It sets us apart as a species and as individuals.”

For example, it’s quite easy to identify Ghasemzadeh without even seeing him. He sounds young yet intelligent enough to have dual doctoral degrees. There’s an inflection of humility in his voice. The curiosity is always there, too. In fact, his peers have noticed, from his work, what his parents noticed among his broken toys: his curiosity leading to great things. Shortly after arriving at UCF, the American Speech-Language-Hearing Association chose Ghasemzadeh for its Early Career Contributions in Research Award.

“It’s also a reminder that I’m early in my career,” he says, “and the sky is the limit.”

At the center of his work as a principal investigator is a belief that progress doesn’t happen alone, but through teamwork.

“You have to surround yourself with different skillsets, all of us willing to take things apart that have never been taken apart, with everyone focused on one goal,” Ghasemzadeh says. “When you win, I win and everyone wins.”

About UCF’s Institute for Simulation and Training

UCF’s Institute for Simulation and Training is an internationally recognized, interdisciplinary institute conducting basic and applied human-centric research that affects nearly all sectors of industry and government, from healthcare to national defense and education to manufacturing. UCF and IST have built the industry, together with more than 200 Central Florida modeling, simulation and training companies and the U.S. Department of Defense. IST is an early adopter whose vision and leadership have spurred new applications and opportunities. (ist.ucf.edu)

They proclaimed there is no better place than UCF, the closest medical school to Kennedy Space Center, to create a new frontier in healthcare as humans prepare for longer missions to the moon, Mars and beyond.

“You are in a global destination for medical innovation,” Michal Masternak told participants in the Star Nona 2026 event in Lake Nona’s Medical City. An anti-aging and cancer researcher at the UCF College of Medicine, Masternak organized the event as part of the Lake Nona Research Council, which is focused on encouraging interdisciplinary scientific partnerships between industry, academia and healthcare.

Space medicine is one of the council’s priorities. Deep space travel and the commercialization of space bring unique health challenges that science is just beginning to explore. The College of Medicine’s focuses on how factors such as microgravity, radiation and isolation impact the human body in space and how that knowledge can drive innovation into diagnostics, treatment and disease prevention for patients on Earth.

Former NASA Administrator and U.S. Senator Bill Nelson told attendees the Artemis voyage’s return to the moon should inspire space medicine experts to make new discoveries.

“We’re in a whole new era, an exciting era, of space exploration that makes this time so special,” Nelson said.

Star Nona’s goal was to bring together experts to understand current research on the health impacts of space travel and what challenges need to be addressed as more professional and commercial space travelers go to the moon and beyond.

The Physical Challenges of Space Flight

Former NASA astronaut Robert Curbeam holds the record for most spacewalks on a single mission. He described how the body feels during launch and splashdown when G-forces are so strong you must remind yourself to breathe. He presented with his former NASA flight surgeon, Smith Johnson, now a faculty member at UCF’s new Center for Aerospace and Extreme Environments Medicine (CASEEM). The two discussed the important relationship between physicians and space travelers before, during and after a mission.

“I loved being an astronaut and flying space shuttles,” Curbeam says. “The only problem with space travel is that not a lot of people get to do it.”

Your Brain Actually Shifts in Space

Living in space causes the body’s fluids to move up to the head and brain. But symptoms of that condition do more than cause puffy faces. Space travel actually causes the brain to shift. Jogi Pattisapu, of the Hydrocephalus and Neuroscience Institute, said as astronauts go to Mars for years-long missions and settle on the moon, scientists will have to understand how living in space affects brain function and create predictive tests and preventative measures. Eye health will be key, as fluid buildup has caused spaceflight-associated neuro-ocular syndrome (SANS) in 70% of astronauts on the International Space Station, leading to farsightedness, optic nerve swelling and eyeball flattening.

“What are we going to do if the pilot goes blind 210 million miles from Earth?” he said.

Team Dynamics in Space

Interpersonal communication is key to any team’s success, but how do relationships change for crews in confined spaces and face additional challenges such as sleep deprivation, isolation and differences in rank and roles. Shawn Burke and Stephen Fiore from UCF’s Institute for Simulation and Training have researched team dynamics in space to understand and prevent collaboration failures that can impact mission success.

Their research has also identified the formal and informal roles crew members play in encouraging positive social interactions and teamwork, especially in long-term missions. Missions to Mars may take up to 36 months and include 20-minute communications delays to and from Mission Control. Team dynamics will impact performance, mental health and affect, Burke said, because “you’re stuck with the people you have.”

Conducting Medical Research in Microgravity: Everything’s Upside Down

The weightlessness of space provides a unique research environment for new discoveries in areas including nutrient production, waste treatment, crystallization and biomanufacturing, said Alain Berinstain, director of the Florida Space Institute at UCF.

“Terrestrially, whenever space can make a difference, it’s a great economic driver,” he said.

In space, air doesn’t slow down processes, he explained, so experiments that involve weight, separation, sedimentation, fluid flow and buoyancy change. His advice to researchers considering space as a lab?

“Turn your experiment upside down. Does it still work? If the answer is no, you have a lot of work to do.”

To advance knowledge in this area, UCF Assistant Professor of Biology , collaborated with international researchers through the Antscan, a global initiave led by the Okinawa Institute of Science and Technology (OIST) and Karlsruhe Institute of Technology (KIT), with contributions from universities and museums.

The effort has led to a Nature Methods publication and created a freely available, morphological database of over 2,000 ant specimens representing nearly 800 species.

“Ants are important to study because they are ubiquitous, abundant and highly varied, ecologically dominant, and some species practice agriculture, facing challenges similar to human agriculture, such as crop pests,” says Sosa-Calvo, who began researching insect diversity at the Smithsonian National Museum of Natural History and the University of Maryland.

Using a fast and powerful X-ray scanning technique, researchers created phenotypically accurate 3D models, providing a detailed look at both ants’ external and internal anatomy that can benefit a wide range of fields.

“There is strong potential for more ant species to be added to Antscan and that other small insect or invertebrate groups create similar repositories of phenotypic data to advance our understanding of biological morphology,” Sosa-Calvo says.

Closing the Gap Between Genetic and Morphological Data

Standard imaging tools used to photograph specimens, like high-resolution cameras, can capture the external morphology of ants from multiple angles, and micro-CT scanning can capture the internal morphology like organs and muscle tissue. However, these methods are time-consuming and limit how many specimens can be studied.

The Antscan initiative is filling this gap of available data by providing a library of morphologically accurate 3D models of ant anatomy. To solve the throughput bottleneck, the team of researchers is using high-throughput X-ray micro-CT scanning powered by a synchrotron particle accelerator.

“The synchrotron particle accelerator produces much higher intensity light beams, resulting in images with higher contrast and faster processing times than a normal micro-CT scanner,” Sosa-Calvo says. “It takes about 3,000 images per specimen in a short period of time. So instead of taking most of the day to scan a single specimen, researchers can scan a single ant in about a minute or so.”

Once the 2D images are captured, they are reconstructed into a 3D tomogram of the specimen, allowing researchers to see fine details from the exoskeleton to internal structures like the nervous system.

Why This Tech Matters for Biodiversity Research

By streamlining the process of scanning smaller specimens and making the 3D models publicly available, the Antscan initiative has opened the door for researchers to study morphology at a scale previously only possible for genetic data, helping morphological research catch up with its molecular counterpart.

It has also helped document the presence of characteristics previously thought to occur in only a single species.

“A few years ago, we discovered that fungus-farming ants—a group of ants that grow fungus for food and are the subject of Sosa-Calvo’s research at UCF—have biomineralized armor that protects them like the shell of marine crustaceans and mollusks,” he says. “With the scans performed in this project, we now know that other species, within fungus-farming ants also have this armor, which appears to be a unique feature among ants.”

Applications in Art and Media

Scientists aren’t the only group that benefits from this extensive library. Since the files are open to the public, Sosa-Calvo says artists are using them to better understand and animate natural ant movement and is a valuable tool for education by engaging students.

He adds that this proven method of collecting morphological data could encourage researchers to generate similar databases, including other Hymenopteran groups, such as wasps andbees, as well as other insect groups like beetles, and other invertebrates.

Sosa-Calvo’s work contributed expertise on insect diversity, particularly within the order Hymenoptera, which includes ants, bees, and wasps. His research focuses on fungus-farming ants, a group known for their highly organized, cooperative colonies and unique agricultural behavior, or fungiculture.

This research was supported by the U.S. National Science Foundation (DEB-1927161).

Researchers and students in the Department of Biology within UCF’s College of Sciences, including the Sosa-Calvo Ant Lab, have contributed to the Antscan initiative.

The study was sponsored by the National Institutes of Health’s National Institute on Aging and was led by UCF Nanoscience Technology Center Professor James Hickman and Research Professor Xiufang “Nadine” Guo. In collaboration with researchers at healthcare tech company Hesperos, the team used lab-grown, human-cell systems designed to model how the body functions to examined how genetic mutations associated with familial Alzheimer’s affects movement. Today, the study was published in Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association.

“Motor deficits may be an earlier indication [of Alzheimer’s],” she says. “If we can detect those changes and intervene earlier, that could help delay the onset of central nervous system symptoms.”

How Movement and Alzheimer’s Are Connected

Familial Alzheimer’s is a rare form of the disease that is hereditary and appears earlier (from 40 to 65 years of age) in people affected than those with the typical condition.

While Alzheimer’s disease is widely associated with memory loss and dementia, clinicians have long observed that some patients show changes in balance, gait (manner of walking) or movement years before cognitive symptoms appear. These early motor changes raise questions about whether parts of the disease begin outside the brain.

Through a tech-powered approach, the team found that the diseased motor neurons — even without involvement from the brain — disrupted the neuromuscular junction, which is central to daily movement.

“This is the first time it’s been demonstrated that deficits in the peripheral nervous system can arise directly from these mutations,” Hickman says. “It means drugs that target the brain may not fix problems in the rest of the body.”

Maintaining motor function may also support overall brain health, as physical activity is known to play a role in cognitive well-being, Guo notes.

How Researchers Build Human Disease Models in the Lab

To explore how these mutations affect movement, the researchers turned to a cutting-edge approach called “human-on-a-chip” technology, which is manufactured through Hesperos, a company co-founded by Hickman. These miniature lab systems recreate the way human cells interact and function in the body, allowing scientists to study disease in a more realistic way than traditional lab or animal models.

The team built a neuromuscular junction-on-a-chip — a small system that mimics the connection between motor neurons and muscle cells. What makes this system powerful is what’s left out: the brain and spinal cord. By isolating motor neurons and muscle cells, the researchers could determine whether movement problems could arise without the central nervous system being involved.

To test this, the researchers paired healthy muscle cells with motor neurons that were created from stem cells and carried familial Alzheimer’s disease mutations. The findings suggest that Alzheimer’s-related movement issues may begin in the network of nerves outside the brain and spinal cord rather than being caused solely by brain degeneration.

Why the Nerve-to-Muscle Connection Matters

The neuromuscular junction is the point where a nerve cell signals a muscle to contract, making movement possible. If that connection is damaged, the body may lose strength, coordination or endurance.

In the study, the researchers measured several aspects of neuromuscular function, including how reliably nerve signals triggered muscle contraction and how long muscles could remain contracted before fatiguing. These measurements mirror the kinds of tests doctors use to evaluate movement disorders.

“You can’t move unless the motor circuit works,” Hickman says. “When a doctor taps your knee to check your reflex, they’re testing that exact connection.”

The Future of ‘Human-on-a-Chip’ Technology

The researchers believe their approach will become increasingly important as drug developers look for more accurate ways to study human disease.

Because the models use human cells and measure real biological function, they can reveal effects that may not appear in animal studies.

For Hickman, the work reflects 30 years of research to better understand disease and help people.

“These systems let us study disease in a way that’s closer to what actually happens in the human body, and that’s what we need to develop better treatments,” he says.

The content is solely the responsibility of the authors and does not necessarily represent the official views of the National Institutes of Health

To reduce these challenges, associate professors of health sciences Michael Rovito and Keith Brazendale in UCF’s Department of Health Sciences are conducting a 6-month intervention study, which is funded by the Florida Department of Health Cancer Innovation Fund.

The National Cancer Institute estimates survival rates for testicular cancer are high, as about 10,000 men are diagnosed each year and fewer than 5% die from the disease — underscoring the need to improve quality of life for these patients.

“Our focus is on finding ways to improve the quality of life for these survivors, and to improve their mental, emotional and social health,” says Rovito, who has researched testicular cancer and men’s health for nearly two decades.

A New Approach to Survivorship Care

Previous survivorship programs have often focused on high-intensity exercise, which can be difficult for patients managing recovery, work and family demands. To develop a more sustainable path to recovery, Rovito and Brazendale are testing a uniquely designed intervention in Florida, known as the Physical Activity and Connectivity for Testicular Cancer Survivors (PACT) program.

PACT combines low-impact, remote, physical activity with an online support network to help survivors navigate psychosocial challenges. Participants engage in regular low-intensity physical activity, such as walking or taking the stairs, and track their progress using Fitbit devices. The devices provide real-time feedback, allowing researchers to set weekly goals and offer personalized guidance. This feedback loop helps participants stay engaged while building sustainable habits.

“We’re seeking an intervention they can do for the rest of their lives,” Brazendale says. “We want these healthy supports to become habit.”

Support Beyond Physical Recovery

Connected through Zoom sessions, PACT program participants receive personalized counsel and encouragement from the researchers directly. They also take part in virtual peer-support sessions led by a social worker and a survivor advocate trained in trauma-informed care. Monthly sessions include breathwork, meditation and discussions on common concerns such as fertility, relationship changes and fear of recurrence.

“The online support session provides coping strategies and tools for the participants to use during the day, when they can feel anxious or depressed or overwhelmed,” Rovito says.

Outside of the meetings, researchers stay in touch regularly with individual messages to participants, sending tailored motivational text messages.

“Our hope is that we are providing realistic physical activity changes that are sustainable when the monitoring ends,” says Brazendale. “We want these survivors to have adopted habits and skills that result in them being healthier over the long-term.”

The researchers say they hope to expand the program to other cancer survivor groups and integrate it into broader survivorship care across Florida, while securing additional funding for larger-scale trials.

The Feasibility of the Physical Activity and Connectivity for Testicular Cancer Survivors (PACT) program is supported by a grant from the Florida Department of Health Cancer Innovation Fund grant number 25C33. 

Now, the U.S. Department of Energy (DOE) has taken notice.

Deneé Lichtenberg was awarded the DOE’s Science Undergraduate Laboratory Internship, giving her the opportunity to further her research at Los Alamos National Laboratory in New Mexico. This premier multidisciplinary research institution is advancing breakthroughs in science and technology to address national security challenges.

The opportunity brings her closer to achieving one of her biggest goals: working at a national laboratory, where she’ll collaborate with experienced researchers and learn how large-scale scientific projects are conducted.

Raised in Titusville, less than an hour away from UCF’s main campus, Lichtenberg says she always knew she’d attend UCF, especially given the strength of its engineering programs. What she didn’t yet know was how far that decision would take her.

“The ability to design and improve materials that impact a variety of fields really motivated me to pursue this discipline.”

She found her path in materials science — a field where physics, chemistry and engineering intersect — which would allow her to study materials from the atomic level to real-world applications.

“Ultimately, everything is made up of materials,” she says. “By changing a material’s structure or composition, you can drastically alter its performance. The ability to design and improve materials that impact a variety of fields really motivated me to pursue this discipline.”

That curiosity has evolved into something bigger: tackling the challenge of sustainably recovering rare earth metals that are vital to the future of energy and technology.

Advancing Sustainable Extraction

Over the past year in the , led by Assistant Professor of Engineering Kausik Mukhopadhyay, Lichtenberg has focused on a breakthrough approach that uses a naturally occurring protein, lanmoudulin.

“The protein can capture rare earth elements from dilute waste streams, and then a small temperature change can trigger the protein to release them so they can be collected,” she says. “This could create a more energy-efficient and environmentally friendly way to recover valuable materials.”

Those materials are critical to everything from renewable energy systems to manufacturing; however, traditional extraction methods rely heavily on large amounts of energy and chemicals sourced from acid mine drainage, coal byproducts and electronic waste.

Lichtenberg’s work points to a sustainable future.

“By developing protein-based systems that selectively capture and release these elements, we could potentially reduce the reliance on traditional extraction,” she says.

At Los Alamos National Laboratory, Lichtenberg will take that work further, designing modified proteins, producing them in the lab and testing how effectively they bind and release rare earth elements.

“It is a very exciting interdisciplinary project that combines protein engineering, materials science and sustainability,” she says. “I hope to continue this research after the internship ends.”

It Takes a Lab — and a Team

But just as impactful as the research has been, the environment that’s shaped it has been.

“Dr. Mukhopadhyay is a fantastic mentor who creates a very supportive and positive environment that encourages learning [both] in and out of the lab,” Lichtenberg says. “The graduate students in the lab have [also] played a huge role in … helping me learn new techniques and [understand] the experiments and science itself.”

Next, she plans to continue her journey as a Knight by pursuing a doctoral degree at UCF, advancing her research as a graduate member of the KM Lab.

For Lichtenberg, the DOE internship isn’t the finish line — it’s just the beginning of reimagining how the world sources its most essential materials.

Presented by the SCHOTT Group and the Ernst Abbe Fund, the award recognizes outstanding contributions to research and technology in glass, glass-ceramics and advanced materials. Richardson shares this year’s honor with Iowa State University researcher Steve Martin.

Together, their work reflects how advances in material structure can translate into real-world applications across industries including healthcare, energy, electronics and advanced technologies.

A Career of Innovation

Over the course of her career, Richardson has focused on advancing the science of optical materials, helping to expand how glass can be used in increasingly complex and demanding environments.

Her work has contributed to the development of materials that can be precisely engineered for performance, supporting innovations in imaging, sensing and optical systems.

“This award recognizes a lifetime of investment in know-how, specialized facilities creation and professional development of skilled personnel, which has resulted in unique prototype materials and technology development,” Richardson says. “These efforts have resulted in products that have gone on to be licensed to partners in this critical application space. I am truly honored to be recognized by one of the global leaders in advanced optical materials for our team’s sustained work in IR materials.”

Advancing Optical Materials

Richardson is recognized for her contributions to the development of optical glasses and infrared materials — specialized materials that control how light is transmitted and detected.

Her research focuses on designing glass compositions at the atomic level to achieve precise optical properties, enabling high-performance systems for infrared imaging, sensing technologies and advanced optics.

“Dr. Richardson’s sustained career has driven significant advancement in infrared material technologies, laying the foundation for next-generation sensing capabilities,” says Winston Schoenfeld, vice president for research and innovation at UCF. “Her relentless pursuit of discovery in optical and infrared materials illuminates UCF’s expanding impact on the frontiers of advanced technologies that continue to shape the future.”

From Fundamental Science to Application

The Otto Schott Research Award highlights the critical connection between fundamental research and industrial application, a hallmark of Richardson’s work. By advancing how glass materials are engineered and processed, her research helps expand the performance limits of existing materials while opening the door to entirely new classes of optical systems.

These innovations include glasses with improved infrared transmission and tailored properties that support emerging technologies in fields including aerospace, electronics, energy production and medical technologies.  Her work has benefited from diverse support ranging from government to industry (local and international) as well as state funding from Florida’s High Technology Corridor (FHTC) which has provided extensive matching funds that have leveraged state funds to support education and training of several dozen graduate and undergraduate students from the Richardson group, over her career.

Why Infrared Materials Matter

Infrared materials play a critical role in technologies that rely on detecting and transmitting light beyond the visible spectrum. These systems are used in applications ranging from medical diagnostics and environmental monitoring to advanced imaging and sensing technologies.

Unlike conventional optical materials, infrared (IR) glasses must be carefully engineered to maintain transparency and performance under demanding conditions, including extreme temperatures and radiation.   Their chemistry is difficult requiring specialized facilities unique to UCF, present in the University’s Optical Material Laboratory, which houses the Glass Processing and Characterization Laboratory (GPCL).  As a result, workforce training in such novel optical material science benefits not only local industry, a stronghold in IR optical materials manufacturing and systems, but government agencies as well.

Richardson’s work focuses on developing glass compositions that meet these challenges while offering greater flexibility than traditional crystalline materials, which are often more expensive and difficult to manufacture.

By enabling more adaptable and scalable materials, her research supports continued advances in imaging systems, sensing technologies and other applications that rely on precise optical performance.

A Global Recognition

The award, endowed with about $29,000, was presented April 13 during the annual meeting at the International Commission on Glass in Lyon, France.

“The research of Steve Martin and Kathleen Richardson clearly shows how essential a deep understanding of material structures is for technological progress,” says Matthias Müller, head of research and development at SCHOTT. “These insights form the basis for developing new glass solutions that perform reliably in real-world applications and expand the boundaries of what is possible.”

Awarded every two years, the Otto Schott Research Award recognizes scientists whose work bridges scientific discovery and practical innovation.
