Daeyeon Lee, Professor and Evan C Thompson Term Chair for Excellence in Teaching in the Department of Chemical and Biomolecular Engineering and member of the Penn Bioengineering Graduate Group, is the recipient of two recent honors.
Daeyeon Lee of the School of Engineering and Applied Science delivers the 2023 Thompson Chair Lecture on April 4, 2023. He spoke about reconnecting in the classroom and building community.
“Students who feel connected with instructors and among peers will invest more time, work harder, and retain information better, because they feel comfortable and safe being in the classroom and making space,” Lee said in his opening remarks. “So, there are clearly lots of positive benefits to having this connectedness among students in the classroom.”
Lee’s lecture, titled “(Re)connecting in the Classroom,” was inspired by the “Great Disengagement” referenced in an article published in The Chronicle of Higher Education last year. It portrayed students as more disconnected and uncertain as they re-entered the campus environment.

In addition, Lee has received the 2022 Outstanding Achievement Award in Nanoscience from the American Chemical Society (ACS).
The annual award recognizes exceptional achievements in nanoscience research and notable leadership in the area of colloidal nanoparticles and application. Lee was chosen from a large group of extraordinary nominees among the invited speakers, “for pioneering research in development of factory-on-a-chip and its application for large scale nanoparticle synthesis and functionalization.”

Researchers at the University of Pennsylvania, AMOLF, and the City University of New York (CUNY) have created a surface with a nanostructure capable of solving mathematical equations.
Powered by light and free of electronics, this discovery introduces exciting new prospects for the future of computing.
Engheta is the founder of the influential field of “optical metatronics.” He creates materials that interact with photons to manipulate data at the speed of light. Engheta’s contribution to this study marks an important advance in his quest to use light-matter interactions to surpass the speed and energy limitations of digital electronics, bringing analog computing out of the past and into the future.
“I began the work on optical metatronics in 2005,” says Engheta, “wondering if it were possible to recreate the elements of a standard electronic circuit at nanoscale. At this tiny size, it would be possible to manipulate the circuit with light, rather than electricity. After achieving this, we became more ambitious, envisioning collections of these nanocircuits as processors. In 2014, we were designing materials that used these optical nanostructures to perform mathematical operations, and in 2019, we anted up to entire mathematical equations using microwaves. Now, my collaborators and I have created a surface that can solve equations using light waves, a significant step closer to our larger goals for computing materials.”
The study, recently published in Nature Nanotechnology, demonstrates the possibility of solving complex mathematical problems and a generic matrix inversion at speeds far beyond those of typical digital computing methods.
The solution converges in about 349 femtoseconds (less than one trillionth of a second), orders of magnitude faster than the clock speed of a conventional processor.

LeAnn Dourte, Practice Associate Professor in Bioengineering, has been awarded a 2023 Provost’s Award for Teaching Excellence by Non-Standing Faculty.
“This award reflects LeAnn’s innovation and dedication in teaching our students in Bioengineering’s biomechanics, biomaterials and biomechatronics classes and labs,” says Ravi Radhakrishnan, Professor and Chair of Bioengineering. “She is a core member of our teaching faculty, spearheading the Department’s initiatives to improve experiential learning and classroom experiences through the SAIL model of education.”
The Structured, Active, In-Class Learning (or SAIL) model of education emphasizes teamwork and dynamic problem-solving. According to Penn’s Center for Teaching and Learning (CTL), SAIL “provides students with the opportunity to struggle through the application of course ideas and material, often the most difficult part of learning for students, with guidance from instructors as well as help from their peers.”
In addition to her pedagogical interests, Dourte serves on the Bioengineering Climate Committee and is also highly involved in student wellness programming, serving as the Department’s Wellness Ambassador for the School.
The Provost’s Awards for Teaching Excellence by Non-Standing Faculty were established in 1988.

There was a time before time when the universe was tiny, dense, and hot. In this world, time didn’t even exist. Space didn’t exist. That’s what current theories about the Big Bang posit, says Vijay Balasubramanian, the Cathy and Marc Lasry Professor of Physics. But what does this mean? What did the beginning of the universe look like? “I don’t know, maybe there was a timeless, spaceless soup,” Balasubramanian says. When we try to describe the beginning of everything, “our words fail us,” he says.
Yet, for thousands of years, humans have been trying to do just that. One attempt came 75 years ago from physicists George Gamow and Ralph Alpher. In a paper published on April 1, 1948, Alpher and Gamow imagined the universe starts in a hot, dense state that cools as it expands. After some time, they argued, there should have been a gas of neutrons, protons, electrons, and neutrinos reacting with each other and congealing into atomic nuclei as the universe aged and cooled. As the universe changed, so did the rates of decay and the ratios of protons to neutrons. Alpher and Gamow were able to mathematically calculate how this process might have occurred.
Now known as the alpha-beta-gamma theory, the paper predicted the surprisingly large fraction of helium and hydrogen in the universe. (By weight, hydrogen comprises 74% of nuclear matter, helium 24%, and heavier elements less than 1%.)
The findings of Gamow and Alpher hold up today, Balasubramanian says, part of an increasingly complex picture of matter, time and space. Penn Today spoke with Balasubramanian about the paper, the Big Bang, and the origin of the universe.
Balasubramanian is Cathy and Marc Lasry Professor in the Department of Physics and Astronomy in the Penn School of Arts and Sciences and a member of the Penn Bioengineering Graduate Group.

When Brian Litt of the Perelman School of Medicine and School of Engineering and Applied Science began treating patients as a neurologist, he found that the therapies and treatments for epilepsy were mostly reliant on traditional pharmacological interventions, which had limited success in changing the course of the disease.
People with epilepsy are often prescribed anti-seizure medications, and, while they are effective for many, about 30% of patients still continue to experience seizures. Litt sought new ways to offer patients better treatment options by investigating a class of devices that electronically stimulate cells in the brain to modulate activity known as neurostimulation devices.
Litt’s research on implantable neurostimulation devices has led to significant breakthroughs in the technology and has broadened scientists’ understanding of the brain. This work started not long after he came to Penn in 2002 with licensing algorithms to help drive a groundbreaking device by NeuroPace, the first closed-loop, responsive neurostimulator to treat epilepsy.
Building on this work, Litt noted in 2011 how the implantable neurostimulation devices being used at the time had rigid wires that didn’t conform to the brain’s surface, and he received support from CURE Epilepsy to accelerate the development of newer, flexible wires to monitor and stimulate the brain.
“CURE is one of the epilepsy community’s most influential funding organizations,” Litt says. “Their support for my lab has been incredibly helpful in enabling the cutting-edge research that we hope will change epilepsy care for our patients.”

His research aims to combat global health threats such as COVID-19 and Alzheimer’s disease by better understanding how proteins function and malfunction, especially through new computational and experimental methods that map protein structures. This understanding of protein dynamics can lead to effective new treatments for even the most seemingly resistant diseases.
“Delivering the right treatment to the right person at the right time is vital to sustaining—and saving—lives,” Magill said. “Greg Bowman’s novel work holds enormous promise and potential to advance new forms of personalized medicine, an area of considerable strength for Penn. A gifted researcher and consummate collaborator, we are delighted to count him among our distinguished PIK University Professors.”
Bowman came to Penn from the Washington University School of Medicine’s Department of Biochemistry and Molecular Biophysics, where he served on the faculty since 2014. He previously completed a three-year postdoctoral fellowship at the University of California, Berkeley.
Bowman’s research utilizes high-performance supercomputers for simulations that can better explain how mutations and disease change a protein’s functions. These simulations are enabled in part through the innovative Folding@home project, which Bowman directs. Folding@home empowers anyone with a computer to run simulations alongside a consortium of universities, with more than 200,000 participants worldwide.
His research has been supported by the National Science Foundation, National Institutes of Health, National Institute on Aging, and Packard Foundation, among others, and he has received a CAREER Award from the NSF, Career Award at the Scientific Interface from the Burroughs Wellcome Fund, and Thomas Kuhn Paradigm Shift Award from the American Chemical Society. He received a Ph.D. in biophysics from Stanford University and a B.S. (summa cum laude) in computer science, with a minor in biomedical engineering, from Cornell University.
“Greg Bowman’s highly innovative work,” Winkelstein said, “exemplifies the power of our interdisciplinary mission at Penn. He brings together supercomputers, biophysics, and biochemistry to make a vital impact on public health. This brilliant fusion of methods—in the service of improving people’s lives around the world—will be a tremendous model for the research of our faculty, students, and postdocs in the years ahead.”
