Dive into the food, fun, and friends of Homecoming weekend

Homecoming is around the corner, and the calendar is full of favorite community events—along with some new opportunities and unique Halloween twists.

The festivities start off October 20, with the Student Org Kickball Tournament, an old tradition making a comeback thanks to Campus Life. Teams receive bragging rights (and prize money to spend on their student organizations). That night the Homecoming bonfire returns to light up the night.

Events really kick into high-gear on October 24 with GRIT-X talks by UMBC faculty and alumni, now given their own special night to celebrate research and creative achievements. The following Friday brings the carnival preview and Athletics Hall of Fame banquet with new Athletics Director Tiffany Tucker. Saturday, October 26, has the most activities to offer—featuring the famous puppy and pet parade, 5k and family fun run, Greek alumni day party, Taste of Maryland crab feast, men’s soccer game vs. Vermont, and much more.

“We do try to have something for everyone,” says Bobby Lubaszewski ’10, M.P.S. ’23, director of communications and marketing for the Office of Institutional Advancement and one of the event organizers. “This year’s event is close to Halloween, so we’re leaning into the Halloween theme with pumpkin painting for the kids and other activities.” 

A chance to celebrate and reconnect

Jess Wyatt, associate director of Alumni Engagement and another of the event organizers, says Homecoming offers Retrievers of all ages and backgrounds and their families a chance to connect. Her own kids enjoy the festivities each year and have made friends with colleagues’ children. 

Sara Osman ’09, modern languages and linguistics, and M.A. ’11, TESOL, recently started attending Homecoming as an opportunity to introduce her young kids to the campus where she and her husband, Karim Yergaliyev ’09, business technology administration, met. “We like to show our three-year-old and six-year-old the places around campus from our stories of the early years when we were dating,” Osman says. “It’s also a nice time to meet up with other alumni and their families.”

The Osman-Yergaliyev family not only re-lives old memories at Homecoming, they also create new ones. Last year, they were some of the few people still at the carnival as the rain came down. “We were playing ring toss when Karim won a stuffed unicorn so large we could barely get it home,” Osman says.

Something for everyone

The plethora of events showcase all UMBC has to offer. You can see demos of advanced AI robot technology one night, reconnect with your childhood on a carnival ride the next, and finish the weekend cheering on the UMBC soccer teams.

Homecoming this year also coincides with UMBC’s annual Livewire new music festival, an exploration of new sounds presented in six concerts over the three days from October 24 – 26.

New this year, the Physics Department is offering tours of the UMBC Observatory, including descriptions of telescope operations and the basics of astronomical detection. “Where else can you go to tour an observatory at Homecoming? That’s really cool!” says Wyatt.

Preparing students for a quantum tomorrow: Lei Zhang brings futuristic computing concepts into the classroom

In the early 20th century, as physicists explored the tiny world of atoms, they noticed some perplexing things: Energy transferred only in chunks; particles that also acted like waves; mysterious links between physically separate systems. Their observations and theories marked the start of the first quantum revolution, which rocked the philosophical world of scientists (Albert Einstein was famously disturbed by some of its implications), but ultimately helped birth the technology of today by enabling the development of physical devices such as computer chips and lasers.

Many scientists believe we are now on the cusp of a second quantum revolution, as quantum concepts are poised to transform the world of information science and technology too. The new revolution offers the promise, among other things, of a new type of computer called a quantum computer. Quantum computers could quickly solve some problems that are extremely difficult for traditional machines—they might also unleash some chaos we’ll have to find ways to prevent. 

Lei Zhang, an assistant professor in the department of information systems, is working hard to prepare students for this quantum information future. In 2023 and 2024, with support from a Hrabowski Innovation Fund Grant, he developed new learning modules on quantum information concepts and integrated them into existing graduate and undergraduate courses in information systems. 

Based partly on the success of that pilot project, Zhang recently received funding from the National Science Foundation to develop a 14-week summer program in quantum information science and technology. The program, which will launch in the summer of 2025, will be open to students from UMBC and nearby Montgomery College. 

“Quantum computing is the next industrial revolution, and there will be an urgent need for skilled professionals in quantum information science and technology,” says Zhang. “This project aims to equip students with the skills and networks to meet that need and advance their careers.”

Quantum’s encryption-breaking challenge

The quantum information revolution is already smashing into our everyday world in the area of internet security. Most internet traffic is kept safe from prying eyes using a technique that works well against hackers using traditional computers but could be broken by a sophisticated enough quantum computer. No quantum computer has reached that point yet, but scientists are making steady progress in that direction, and experts are worried enough to start mandating security changes. 

In 2022, the White House released a National Security Memorandum coordinating the actions of various federal agencies in a move toward quantum-resistant forms of encryption for their computer systems. 

“The government will be one of the leaders in the change, but the whole private sector will need to follow,” Zhang says. “Everyone will need to update their systems.”

Zhang is focusing the summer program on this challenge. Students will learn about quantum computers and how they could break traditional encryption, and will also learn about new security algorithms, called post-quantum encryption algorithms, that are not as vulnerable to quantum attacks.

“Quantum computing is the next industrial revolution, and there will be an urgent need for skilled professionals in quantum information science and technology. This project aims to equip students with the skills and networks to meet that need and advance their careers.”

After six weeks of active and immersive learning activities, the students will engage in eight-week-long internships at local tech companies or in Zhang’s UMBC lab, where they will put their newfound knowledge and skills to use. At the completion of the summer program, the students will earn a MicroBachelors certificate from the online education company edX. 

Partnerships advance outreach and teaching

Zhang is partnering with individuals and programs across UMBC to make his summer program successful. Zhang’s main collaborator on the project, assistant information systems professor Karen Chen, specializes in the study of how technology can improve learning. The team also includes information systems faculty Aryya Gangopadhyay, Michael Brown, and C. Augusto Casas

Zhang is partnering with UMBC’s Center for Women in Technology, UMBC’s Cybersecurity Institute, and Montgomery College to recruit a diverse range of students for the summer program. 

The project will be guided by the expertise of local leaders from government and private industry and its effectiveness will be evaluated by UMBC’s Chris Rakes, a professor of mathematics education.

Going forward, Zhang plans to continue scaling up his quantum education efforts. The coursework from the summer program will be made freely available for other educational institutions to use. It could also be incorporated into programs for adult learners. 

In collaboration with the National Institute of Standards and Technology, headquartered in Gaithersburg, Maryland, Zhang also plans to use knowledge generated from the summer program to organize professional development workshops for instructors in four-year and community colleges. 

The impact of Zhang’s efforts can already be seen on the individual level. Khushdeep Kaur, a master’s student in information systems, first heard about quantum computing from Zhang. “I felt amazed and eager to learn more about the technology,” she says. She is now part of Zhang’s research group, studying quantum computing topics. 

Dongchan Kim, a senior majoring in information systems, also joined the lab after taking one of Zhang’s classes in spring 2024.

“I really enjoyed learning about technology that could become the ‘next big thing,’” he says. “Like AI, I think quantum computing has the power to transform industries. I look forward to contributing to its development in the future.”

Upal Ghosh appointed to D.C. mayor’s Leadership Council for a Cleaner Anacostia River

On September 12, UMBC’s Upal Ghosh, from the Department of Chemical, Biochemical, and Environmental Engineering, was sworn in as a member of the Washington, D.C., mayor’s Leadership Council for a Cleaner Anacostia River (LCCAR). The council consists of 25 high-level government officials, community leaders, and environmental experts who support the vision of a swimmable and fishable Anacostia River. The members meet quarterly to advise the D.C. government on ongoing restoration projects. 

The Anacostia River, which runs from Prince George’s County in Maryland into Washington, D.C., before joining the Potomac River and ultimately flowing into the Chesapeake Bay, has historically suffered from high levels of industrial pollution and contamination from sewage overflow. In recent years, government officials have been making concerted efforts to clean up the river. UMBC was invited to sit on the council, with Ghosh as the representative, based on the university’s key contributions to these clean-up efforts.

Since 2016, Ghosh and his UMBC colleagues and students have developed innovative methods of measuring contaminants in the river and created models to elucidate where the contaminants come from and how they travel through and accumulate in the water, sediment, and aquatic life, such as fish. Nathalie Lombard, a research assistant professor at UMBC who has played a significant role in the projects, will serve as the alternate representative on the LLCAR when Ghosh cannot attend. 


In addition to his work on the Anacostia, Ghosh and his students have studied and contributed to the cleanup of the waterways throughout Maryland, Delaware, and across the country.  “Students learn a lot from being out in the field,” Ghosh says. “They learn how the science and engineering we do helps guide major decisions. Our ultimate goal is making a positive difference in the health of the river, lake, or bay. That gives me a lot of excitement, and it really motivates the students too.”

Lee Blaney assumes presidency of the Association of Environmental Engineering and Science Professors

Professor Lee Blaney, in the Department of Chemical, Biochemical, and Environmental Engineering, formally assumed the role of president of the Association of Environmental Engineering and Science Professors (AEESP) at a board of directors meeting in early September.

AEESP is a nonprofit organization founded in 1963 to foster inclusive connections between environmental engineering and science researchers and educators. It provides programs for members to develop the academic networks and career skills needed for professional success, increase equitable societal impact of environmental engineering and science scholarship and creative expression, and reimagine the skills necessary for environmental engineers and scientists to provide solutions that benefit regional, national, and global communities. 

The association currently has more than 1000 members from universities around the world. AEESP assists its members in improving education and research programs, encourages graduate education, and provides information to government agencies and the public. The biennial AEESP Research and Education Conference brings the field together to share research, teaching, and outreach outcomes. Blaney’s term as president will include the next conference, which is scheduled to occur in May 2025 at Duke University. 

“We’re excited about Dr. Blaney’s new role as president of AEESP,” says Mark Marten, the chair of the Department of Chemical, Biochemical, and Environmental Engineering. “His deep involvement with this organization not only makes a positive impact in our discipline, but also raises awareness of our department and UMBC in this influential community.” 

Blaney and his research group study environmental contaminants of emerging concern, such as per- and polyfluoroalkyl substances, or PFAS, which are sometimes called “forever chemicals” because of the way they persist in the environment. They also research how to recover vital resources, such as nitrogen and phosphorus, from waste streams to improve water quality and ensure sustainable development. Blaney was a winner of the 2021 James J. Morgan Early Career Award from the American Chemical Society, and has also been recognized for the quality of his teaching and mentorship.

Blaney joined AEESP in 2012 after starting as an assistant professor at UMBC. He quickly joined and became chair of the AEESP Membership & Demographics Committee, through which he led efforts to initiate a student video competition (check out this winning video from UMBC). He also led efforts to document the demographics of environmental engineering faculty and students in reports such as “Trends in Population and Demographics of U.S. Environmental Engineering Students and Faculty from 2005 to 2013” and “Another Grand Challenge: Diversity in Environmental Engineering.”

In 2021, Blaney was elected to the AEESP board of directors. Since that time, he has led a number of initiatives aimed at improving inclusion. During his one-year term as president, he will lead the board and executive committee, provide new charges to standing committees, correspond with members, represent AEESP at conferences and meetings, and drive new initiatives to grow the organization and support its members.

In his first presidential address to AEESP, given in June, Blaney told members of how he found direction as an undergraduate student after attending a talk by environmental engineer Arup SenGupta, who spoke of efforts to remove arsenic from contaminated groundwater in rural villages in India.

“His passion and dedication to helping those without other resources inspired me, set me on the path to becoming an environmental engineer, and helped me to become a better person,” Blaney said. He hopes to bring these same values to AEESP and its members.

As president of AEESP, Blaney plans to develop an “AEESP Experts” program, which will connect environmental experts with reporters, and also an “AEESP Communities of Practice” initiative, which will gather small groups of AEESP members to develop new resources, such as new course material on climate change or best practices for graduate student recruitment, which can be shared with the whole community.

UMBC chemical engineering student intern finds purpose giving patients hope

A few weeks into her summer internship with pharmaceutical company AstraZeneca, rising senior Ortisemoyowa “Moyo” Ikomi, chemical engineering, attended an event celebrating a milestone in the company’s construction of a new drug manufacturing plant in Rockville, Maryland. During the event, the organizers played a video featuring a young girl whose seemingly terminal cancer was cured with immunotherapy drugs—the same type of drugs that would be manufactured in the new facility.

“This girl was in hospice care, at home with her family who thought they might just have to wait for her life to end, and this drug gave her a new lease on life. It drove home for me how important this work is, and how I would love to keep working in the pharmaceutical industry,” says Ikomi.

Ikomi landed her internship with AstraZeneca after talking with a company representative at the UMBC Career Fair. She worked on the company’s management of the planned Rockville plant, investigating a software tool that could track construction progress.

“It’s not traditional chemical engineering, more within the realm of project management of large-scale engineering projects. I’m definitely enjoying it,” Ikomi says. “I’ve learned so much during the internship. The experience has made me think I’d like to continue working in the engineering project management sphere.”

Ikomi credits the UMBC Career Center with supporting her throughout her internship application process—consulting with her on application timelines, uncovering resources for finding job openings, and offering tips for honing her resume and interviewing skills. “They offer an invaluable service,” she says. “Even more students could benefit from using them.” 

Ikomi, who came to UMBC from Lagos, Nigeria, says she arrived thinking she wanted to be a scientific researcher. When she realized basic research wasn’t the best fit for her, faculty and fellow students listened as she talked through her dilemma and offered advice on other options. She found that her true passions lay in shepherding discoveries from the lab to the wider world, where they could directly impact people’s lives.

Since that celebration event at AstraZeneca, Ikomi says she often thinks back to the video of the young girl who was cured of cancer. “When I think of this internship as a whole, my mind always goes to that experience. That moment crystallized that this type of work is what I want to dedicate my career to.” 

Leah Narat ’24 lands elite NASA internship in business intelligence

NASA holds a special place in the public’s imagination. The federal space agency has delivered astronauts to the moon, collected breathtaking images of the cosmos with space telescopes, explored Mars with robotic rovers, and sent satellites into orbit to keep watchful eyes on our own life-supporting planet.

Leah Narat ’24, business technology administration, shares in the awe. She knew that getting an internship at NASA was highly competitive—around 5 percent of those who apply get offered positions—but she didn’t let the high bar dissuade her from trying.

“Honestly, being at NASA was something that I never thought I would achieve, but I put my application out there, and here I am,” says Narat, who worked as a business intelligence intern at the NASA Goddard Space Flight Center in Greenbelt, Maryland, this summer. “It’s been wonderful.”

During the internship, Narat worked on computer systems that help keep NASA missions safe and its employees engaged. In one project, she created and updated databases to track awards given to NASA employees. The agency will use the information to maximize employees’ recognition and success and guide them toward career paths that best take advantage of their strengths. 

“It’s been great to have this real world experience, where I can get my hands dirty and decide: Is this the type of work I want to do?” Narat says. “It’s also great that I can receive upper-level credit hours for the internship.”

In another project, Narat sorted information from meetings during which teams debriefed after they completed projects. She identified insights, recommendations, and lessons learned—valuable information that NASA can use to better manage projects in the future.

“Safety is a big priority for NASA, so they have requirements to make sure that each project is scrutinized and every possible improvement is considered,” Narat says.

Narat says her experience working at NASA helped solidify her interests in data analytics and database management. She credits Handshake, UMBC’s job and internship search platform, with helping her find and apply for the position.

“The best part of the experience has been meeting people, networking, and making connections,” says Narat. She was also thrilled when the interns got to visit NASA’s Wallops Flight Facility in Wallops Island, Virginia, from which the agency launches a variety of space and high-altitude missions. 

“I got to actually stand on the launch pad where rockets blast off,” says Narat. “It was just wild.”

UMBC scientists show twisted carbon nanotubes might power “wind-up” sensors and other devices

An international team of scientists, including two researchers who now work in the Center for Advanced Sensor Technology (CAST) at UMBC, has shown that twisted carbon nanotubes can store three times more energy per unit mass than advanced lithium-ion batteries. The finding may advance carbon nanotubes as a promising solution for storing energy in devices that need to be lightweight, compact, and safe, such as medical implants and sensors. The research was published recently in the journal Nature Nanotechnology.

Sanjeev Kumar Ujjain, from CAST, was a lead researcher on the work. He started the project while at Shinshu University, in Nagano, Japan, and continued after arriving at UMBC in 2022. Preety Ahuja, from CAST, also contributed to the material characterization aspects of the research.

Straws of 1-atom-thick carbon

The researchers studied single-walled carbon nanotubes, which are like straws made from pure carbon sheets only 1-atom thick. Carbon nanotubes are lightweight, relatively easy to manufacture, and about 100 times stronger than steel. Their amazing properties have led scientists to explore their potential use in a wide range of futuristic-sounding technology, including space elevators.

To investigate carbon nanotubes’ potential for storing energy, the UMBC researchers and their colleagues manufactured carbon nanotube “ropes” from bundles of commercially available nanotubes. After pulling and twisting the tubes into a single thread, the researchers then coated them with different substances intended to increase the ropes’ strength and flexibility. 

The team tested how much energy the ropes could store by twisting them up and measuring the energy that was released as the ropes unwound. They found that the best-performing ropes could store 15,000 times more energy per unit mass than steel springs, and about three times more energy than lithium-ion batteries. The stored energy remains consistent and accessible at temperatures ranging from -76 to +212 °F (-60 to +100 °C). The materials in the carbon nanotube ropes are also safer for the human body than those used in batteries.

The researchers envision that twisted carbon nanotube ropes may one day power a range of devices, including wearable health sensors and medical implants that could harvest energy from the body’s movements. (Graphic “NanoRope Mobility” created by Sanjeev Kumar Ujjain using Copilot AI.)

“Humans have long stored energy in mechanical coil springs to power devices such as watches and toys,” Kumar Ujjain says. “This research shows twisted carbon nanotubes have great potential for mechanical energy storage, and we are excited to share the news with the world.” He says the CAST team is already working to incorporate twisted carbon nanotubes as an energy source for a prototype sensor they are developing.

With eye to research, UMBC expands partnership with Baltimore-based energy company Constellation

UMBC is strengthening the university’s research connection with the energy company Constellation, expanding on a partnership of more than 20 years with the Baltimore-based business. Constellation, the nation’s largest producer of carbon-free energy, funds scholarships and has endowed a professorship in mechanical engineering at UMBC, regularly recruits students for internships and jobs, and hosts its annual Youth Energy Summit on the UMBC campus.

In March, UMBC and Constellation signed a Master Research Agreement, which will facilitate greater research collaboration between the two organizations. In April, Constellation sent representatives to the College of Engineering and Information Technology’s (COEIT’s) inaugural Research Day to connect with UMBC faculty and students. And in June, research leaders from both organizations met to discuss potential areas of joint work, including carbon-free energy generation, environmental protection and pollution remediation, and efforts to make the power grid more resilient and secure. 

“The best research will happen as we grow this partnership organically,” says Anupam Joshi, acting dean of COEIT. “We are proud to be a Tier 1 university partner of Constellation Energy. The interactions of our faculty and students with Constellation’s representatives during Research Day have already led to initial ideas where we can work together. We are also actively pursuing collaborations in other areas of mutual interest and environmental importance.” 

“As part of our efforts to accelerate the nation’s clean energy future, it’s vital that we enhance our understanding of the emerging technologies being developed today,” said Uuganbayar “Ugi” Otgonbaatar, Constellation’s director of Technology Strategy, Grants, and Partnerships. “We are grateful for our longstanding partnership with a leading local institution in UMBC and look forward to continuing to explore its research portfolio as part of our broader collaboration.”

Karen Chen wins NSF CAREER award to build tools to empower students with data

When Karen Chen’s now teenage son was in third grade, he would complain that math homework was “boring.” Chen wanted to change his perspective. She presented him with extracurricular math problems and coached him through the most challenging ones. Being a data scientist, she also recorded the sessions and rigorously analyzed the video and audio for insights about his learning experience. One of her key takeaways: Her son rode an emotional roller coaster as he worked through difficult problems. Her attentive tutoring helped him through the confusion and frustration to reach the joy at the end. 

Since the project with her son eight years ago, Chen, an assistant professor in the Department of Information Systems at UMBC, has made learning analytics a pillar of her research. The field seeks to collect and analyze data about students and their environment with the goal of improving learning outcomes. Chen recently won a National Science Foundation (NSF) CAREER award to advance this research with a new project that puts students at the center of learning analytics—not just as subjects who supply data, but also as the designers of analytical tools and users of the insights they provide. 

Chen’s CAREER award marks the 50th time a UMBC faculty member has received the prestigious grant, which the NSF established to support early-career faculty who have the potential to serve as leaders in integrating research and education. 

“I’m really excited about this project,” Chen says. “I love teaching and interdisciplinary research and this is an excellent opportunity to combine them.”

Learning analytics, “for students, by students”

Chen’s Lab for Informatics for Human Flourishing at UMBC is dedicated to using data to improve people’s lives. “I like to center all my research on promoting human flourishing, meaning people are not just surviving, but thriving. I use this concept as a North Star,” explains Chen.

Education is a key pathway to advance human flourishing, Chen says, and she looks forward to improving student learning experiences and outcomes through her CAREER award project.

The project will start by engaging students enrolled in Foundations of Data Science (IS 296), a relatively new undergraduate course at UMBC, introduced by Vandana Janeja, information systems. IS 296 recently became a general education program course at UMBC, open to all majors with no prerequisites. 

Under Chen’s guidance, students in the class will collect data about their lives—how much sleep and exercise they get, how much time they spend talking to friends and family, how stressed they are feeling, and more. They’ll also gather information related to their classes, such as already available data about how often they log into and use the university’s learning management system, Blackboard, and track how much time they spend focusing on classwork (versus, say, becoming distracted by other open tabs on their computers.) The data will be available only to individual students and those they designate as trusted collaborators. 

Students will then work through data science activities, analyzing the information they gathered and seeing if they can gain insights to improve their well-being and academic success. At the same time, they will build a critical competency called self-regulated learning, says Chen.

Based on feedback from the class, Chen will then work with students to design and develop an online platform, called “Live Data Lab,” where a broader student community can find tools to track and analyze their own well-being while learning basic data science concepts and techniques. This platform will also provide opportunities for students to explore creative expression of data through mediums such as digital data stories, data art, data comics, or data memes.

Chen will test-run the platform with around 500 students, including first-year UMBC students enrolled in a new seminar course offered by Academic Engagement and Transition Programs, as well as students enrolled in UMBC’s Department of Education pre-service teacher preparation programs. The project will also engage students from community college partners such as Montgomery College.  

Empowering students for success

UMBC is an excellent place to conduct the project, Chen says, because it has a culture of promoting student success in its diverse community by empowering students with support and tools. UMBC has also been a leader in learning analytics, already gathering data about how students use its learning management systems to improve students’ learning outcomes, and protecting that data’s privacy, Chen adds. 

“This project would not be possible without the support of the Division of Information Technology, in particular John Fritz and his team, who created the Check-My-Activity tool, a student-facing learning analytics tool that has been in operation in UMBC for more than a decade,” Chen says. The project will also be supported by information systems faculty Andrea Kleinsmith, an expert in human-centered design, and Zhiyuan Chen, an expert in data privacy, Chen adds. 

“The question driving the work is: How can we best center students’ voices and empower them in the data-driven decision-making process?” Chen says. “This project will provide many opportunities for undergraduates and graduate students at UMBC to get involved. Not only will they contribute to the research, but I hope they will also become deeply engaged with their learning and empowered to become better versions of themselves through data, scientific evidence, and reasoning.” 

How to count time: Professor Curtis Menyuk brings his expertise in optics to an age-old problem

Time—We buy it and spend it, save it and waste it; it seems to race by as we watch our children grow or drag on in the last hour of a Friday work day. Shakespeare marked “time’s thievish progress” in wrinkles like “mouthed graves.” But for a more objective accounting, humans have turned to physics, measuring days, hours, minutes, and seconds using rhythmic natural phenomena such as the Earth’s rotation, the swing of a pendulum, the vibration of quartz crystals, and, most recently, the oscillation of light waves. 

“I have been fascinated by time and how we tell it for as long as I can remember,” says Curtis Menyuk, a professor in the Department of Computer Science and Electrical Engineering, who for the past 20 years has applied his expertise in optics to a host of questions at the frontiers of time-keeping science.

Defining time

We measure time in chunks—the international standard unit for a chunk being the second. For centuries, the second was understood as a fraction of an Earth day, but because the Earth’s rotational speed varies slightly, a second defined in this way is not constant. The invention of atomic clocks in the middle of the 20th century allowed scientists to redefine the second based on the (as far as we know) unchanging properties of atoms. Today, one second is the time it takes the electric field of microwaves that are absorbed and emitted by cesium atoms at a specific frequency to cycle up and down 9,192,631,770 times.

But it’s likely the second will soon be redefined again. Newer versions of atomic clocks, called optical clocks, measure time’s passage with visible light instead of microwaves. Visible light waves oscillate much faster than microwaves—and faster oscillations in principle mean better time-keeping. Many optical clocks keep time so well that if they could have started running when the universe began and kept going until today, they still would not have lost or gained a single second.

Shortly after the first all-optical atomic clocks were developed in the early 2000s, Menyuk began collaborating with scientists at the National Institute of Standards and Technology (NIST) to study a key component of the clocks called a frequency comb. Frequency combs provide the bridge between high-frequency light, which forms the heart of optical clocks, and modern electronics, which can only process lower-frequency signals. The combs are made from extremely short light pulses, called solitons, that travel without dispersing, similar to how tsunami waves traverse the ocean. And it just so happens that Menyuk is an expert on solitons, having become captivated by the “almost magical balance” of forces that keep the waves from being torn apart ever since he first learned about the phenomenon at the age of 27. 

Shrinking the world’s most precise clocks

In 2013, Menyuk collaborated with a colleague to derive the basic equations describing how solitons are created when light travels in a circle around a small crystalline disk called a microresonator. Microresonators offer a compact alternative to the bulky lasers originally required to make frequency combs, and Menyuk and some of his NIST colleagues recently published a paper in the prestigious scientific journal Nature that reports a new approach to simplifying the use and improving the performance of microresonator-based combs.

Shrinking the components of optical clocks is a key step toward taking full advantage of their powers. Their potential extends beyond the possibility of one day setting the time for your computer. Atomic clocks are a critical component of today’s GPS system, which helps billions of people find their way around each day. Compact optical clocks might improve GPS accuracy to within a few centimeters. Optical time-keeping can also serve as a back-up to GPS, which is vulnerable to disruptions and attacks. Menyuk is tackling this very issue with the recent launch of the Center for Navigation, Timing, and Frequency Research at UMBC, which he directs in collaboration with the Army Research Laboratory and other partners.

New clocks may even make possible groundbreaking discoveries about the fabric of the universe, helping scientists search for dark matter and test whether the laws of physics change over time.

For Menyuk, passing time has not noticeably dimmed his prolific research output (of which clocks are just a portion). And while the years add age, they also add perspective. “Curtis is a leading theorist with decades of experience,” says Kartik Srinivasan, one of the NIST scientists who collaborated with Menyuk on the recent Nature paper. Srinivasan noted that some of the equations he learned in grad school for predicting light’s behavior in optical fibers were developed by Menyuk in the 1980s. “Curtis’ reservoir of historical knowledge is not something you can easily find.” Even with the use of an atomic clock.

Molly Mollica wins American Heart Association Career Development Award

Molly Mollica, an assistant professor in mechanical engineering who joined UMBC in August 2023, has been selected for an American Heart Association (AHA) Career Development Award, which will provide more than $200,000 to fund her research for the next three years.

Mollica studies the biomechanics of blood platelets, which play an essential role in healthy blood clotting, but can also contribute to the formation of blood clots that cause heart attacks and strokes. Bleeding and clotting have been shown to vary between males and females, but the reasons are not well understood. In her AHA-funded research, Mollica will investigate how platelets from males versus females, and from donors with varying hormone levels, respond to and generate mechanical forces. She hopes the information she uncovers will help doctors better understand healthy platelet function, design more inclusive health research, and develop better treatments.

“I’m honored to receive this award,” said Mollica. “We look forward to better understanding sex and hormone differences in platelet function. This research is important in providing tools to develop new preventative and curative therapeutics.”

Capping years of rising success, UMBC chemical engineering club shines as student conference hosts

On the first weekend of April, hundreds of chemical engineering students from across the Mid-Atlantic converged on the UMBC campus for two days of learning, networking, and friendly competition. They heard talks from academic and industry leaders, attended workshops and a career fair, competed in rounds of ChemE Jeopardy, mixed chemicals to power small cars along a track in the ChemE Car competition, and mingled over catered lunches, dinners, and cups of evening hot cocoa. 

The activities were all part of the 2024 Mid-Atlantic Student Regional Conference of the American Institute of Chemical Engineers (AIChE)—hosted by the UMBC student chapter of the national group. Around 400 people attended the event, an increase from last year’s conference at Virginia Tech. Organizing the logistics, recruiting speakers and sponsors, securing rooms, and ordering thousands of plates worth of food presented a formidable challenge—one that the UMBC students tackled with aplomb. 

“I am feeling fantastic after the conference,” says Pavan Umashankar ’25, chemical engineering and biochemistry and molecular biology, who served as the chair of the conference organizing committee. “I am super proud of everyone’s commitment and dedication to make it a resounding success.”

“Truly, I could gush about the UMBC conference planning team all day,” says Alyssa Block, the membership associate of ChemE student programs for AIChE. “These students really are the future leaders of their profession and of AIChE: engaged, excited, collaborative, supportive of each other, and willing to lend a hand.” 

A club on the upswing 

Hosting an AIChE regional conference for the first time at UMBC marked a milestone for a student club that has seen increasing levels of engagement and success in recent years. While many college clubs across the country are in decline post-Covid, UMBC’s AIChE student chapter is on a clear upward trajectory. The club sent its first team to compete in ChemE Jeopardy at the spring 2019 AIChE regional meeting. Just three years later, the UMBC team won the national ChemE Jeopardy competition. 

Neha Raikar, a senior lecturer in the Department of Chemical, Biochemical, and Environmental Engineering (CBEE) and one of the advisors to the student AIChE chapter, remembers attending the 2019 meeting: “Back then, we wondered if we would ever be able to host a regional conference at UMBC,” she says. “We’ve achieved that goal.” 

It was especially remarkable, she adds, to see some members of UMBC’s first ChemE Jeopardy and ChemE car teams return to this year’s conference as industry representatives.

Strong attendance and smooth conference logistics weren’t the only successes of the weekend—UMBC also triumphed in the ChemE Jeopardy and ChemE car competitions

“Planning for the conference was already a significant undertaking, and on top of that, many of our students participated, and excelled, in the competitions,” says Raikar. “Their achievements not only showcased their individual capabilities but also the strength of our club as a whole, which is growing and thriving.”

A winning formula

AIChE chapter members and their advisors ascribe the club’s success to the hard work and dedication of the students coupled with the support of the CBEE department, college, and university. Thirteen CBEE students formed the conference planning committee, which met regularly to ensure all conference planning efforts were on track. An additional 37 students and 14 faculty and staff also volunteered their time—as check-in staff, poster and presentation judges, and more. About 10 UMBC alumni actively participated in the conference, and others contributed to fundraising efforts, helping the organizing committee secure sponsorships from notable companies such as AstraZeneca, ExxonMobil, Advanced Thermal Batteries, and Astek Diagnostics and from the chemical engineering department of Columbia University. 

An Dang ’24, chemical engineering, led the fundraising efforts. She gamely approached industry representatives at the UMBC career fair and made the pitch. “I’m not an extrovert, and being in these roles forced me to go out of my comfort zone,” she says.

“Securing sponsorships was vital for making the conference possible, and An did a remarkable job” says Mariajosé Castellanos, another CBEE faculty who advises the AIChE chapter. Castellanos also praised the management skills of conference planning committee chair Umashankar. “Despite his modesty, Pavan is a true mastermind in everything he does,” she says.

For their part, the students applauded the support of the CBEE department, especially the work of their two advisors, Raikar and Castellanos, and the event planning support of Andrea Miller, the CBEE graduate program coordinator.

The conference was both a marker of the club’s success and an opportunity for individual students to grow their skill sets.

“I have developed leadership and project management skills, which will be incredibly useful throughout my professional career,” says Umashankar. 

Ben Welling ’25, chemical engineering, the leader of the UMBC ChemE car team, believes his experience with the competition helped him land internships. “I talked about it extensively with employers. They like leadership experience and it shows you are willing to do more than is required.” 

Raikar sees a bright future for the student stars of this year’s conference and for the club as a whole. “I hope the conference will boost the club membership and participation of students in other AIChE activities,” she says. And, she adds, the conference shows that with support, “UMBC students can accomplish any task.”
