Sharon Kuo, a graduating senior in Mechanical Engineering and Applied Mechanics (MEAM), is the inaugural recipient of the Madison “Maddie” Magee Award for Undergraduate Excellence.
Kuo, who is also minoring in Mathematics, comes to Penn from Taipei, Taiwan. Her interests within her major include mechanical design and product design, and she is passionate about space exploration and advancing human spaceflight.
This award will continue to be presented each year to a Penn Engineering senior who best exemplifies the energy, enthusiasm and excellence that was Maddie.
The award for Undergraduate Excellence was established in honor of Madison “Maddie” N. Magee, who graduated with both a bachelor’s degree in Mechanical Engineering and Applied Mechanics (MEAM) and a master’s degree in Bioengineering (BE) in 2021. Maddie passed away while hiking the Pacific Crest Trail on May 28, 2022. Read more about this award here.

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.”
Four University of Pennsylvania undergraduates have received 2023 Goldwater Scholarships, awarded to second- or third-year students planning research careers in mathematics, the natural sciences, or engineering.
They are among the 413 students named 2023 Goldwater Scholars from more than 5,000 students nominated by 427 academic institutions in the United States, according to the Barry Goldwater Scholarship & Excellence in Education Foundation. Each scholarship provides as much as $7,500 each year for as many as two years of undergraduate study.
Penn has produced 59 Goldwater Scholars since Congress established the scholarship in 1986 to honor U.S. Senator Barry Goldwater.
Angela Song (Class of 2024)
Angela Song, from Princeton Junction, New Jersey, is a third-year majoring in bioengineering in the School of Engineering and Applied Science. She is interested in engineering molecular therapeutics for disease. She works in Douglas C. Wallace’s lab in the Center for Mitochondrial and Epigenomic Medicine at the Children’s Hospital of Philadelphia, focusing on designing engineered proteins with mitochondrial applications. At Penn, Song is the vice president of design for UnEarthed, a student-published educational magazine for West Philadelphia elementary school children, and president of the Penn American Red Cross Club. After graduating, Song plans to continue pursuing research through a Ph.D. in bioengineering.

Penn Engineering announced the faculty recipients of the 2023 Student Choice Awards (formerly the Teaching and Advising Awards). Each year, the Penn Engineering undergraduate student body thoughtfully selects the recipients of these awards for their dedication in teaching, mentorship and student advocacy. This year also features two new awards, the Student Advocacy Award and the Undergraduate Research Mentoring Award.
Brit Shields, Senior Lecturer in Bioengineering, is the inaugural recipient of the Student Advocacy Award. This award is presented to a member of the Penn Engineering faculty by the Underrepresented Student Advisory Board in Engineering in recognition of their outstanding commitment to women and underrepresented student advocacy, equity and inclusion.
Dr. Shields poses with her award at the annual Penn Engineering Awards Ceremony.
Shields completed a Ph.D. at Penn in 2015 in History and Sociology of Science, with a dissertation on scientific diplomacy through the example of Richard Courant and New York University, where Shields completed an M.A. in Humanities and Social Thought: Science Studies.
She was promoted to Senior Lecturer in Bioengineering in 2019. She has brought her expertise in the history and sociology of science to her leading role in developing and improving the ethics curriculum for all students in the School of Engineering and Applied Science.
