Five from Penn elected to the American Academy of Arts and Sciences in 2023
Faculty from the School of Arts & Sciences, School of Engineering and Applied Science, Graduate School of Education, and Perelman School of Medicine are recognized this year for contributions to physics, engineering and technology, education, economics, and microbiology and immunology.
The Academy of Arts and Sciences elected five Penn faculty this year, (left to right): (top) Mirjam Cvetič of the School of Arts & Sciences (SAS); Nader Engheta of the School of Engineering and Applied Science and SAS; and Vivian L. Gadsden of the Graduate School of Education and SAS; (bottom) Petra E. Todd of SAS, and E. John Wherry of the Perelman School of Medicine.
Mirjam Cvetič is the Fay R. and Eugene L. Langberg Professor of Physics and Mathematics in the School of Arts & Sciences. She is part of the high energy theory group at Penn, which studies the fundamental forces of nature, early universe cosmology and mathematical physics. Cvetič is an expert on issues relating to string theory and its consequences for particle physics. Her research spans broad thrusts in fundamental theory, ranging from gravitational physics and work at the interface with differential and algebraic geometry to leading efforts in constructions of string theory solutions and the study of their physics implications. She won the University of Maryland Physics Distinguished Alumni Award in 2007, and is a recipient of the Friedrich von Siemens Research Award of the Alexander von Humboldt Foundation in 2020.
Nader Engheta is the H. Nedwill Ramsey Professor, with affiliations in the departments of Electrical and Systems Engineering (primary appointment), Bioengineering (secondary appointment) and Materials Science and Engineering (secondary appointment) in the School of Engineering and Applied Science; and Physics and Astronomy (secondary appointment) in the School of Arts & Sciences. His current research activities span a broad range of areas including optics, photonics, metamaterials, electrodynamics, microwaves, nano-optics, graphene photonics, imaging and sensing inspired by eyes of animal species, microwave and optical antennas, and physics and engineering of fields and waves. He has received numerous awards for his research, including the 2023 Benjamin Franklin Medal in Electrical Engineering, the 2020 Isaac Newton Medal and Prize from the Institute of Physics (U.K.), the 2020 Max Born Award from OPTICA (formerly OSA), induction to the Canadian Academy of Engineering as an International Fellow (2019), U.S. National Academy of Inventors (2015), and the Ellis Island Medal of Honor from the Ellis Island Honors Society (2019).
Vivian L. Gadsden is the William T. Carter Professor of Child Development and professor of education in the Graduate School of Education; faculty member in Africana Studies and in Gender, Sexuality, and Women’s Studies in the School of Arts & Sciences; and faculty director of the Penn Child Research Center. Her research and interests focus on learning and literacies across the life-course and addresses issues of culture, equity, and access for young children and families in historically marginalized communities. Her collaborative research projects draw upon interdisciplinary frameworks that examine early childhood development, parenting, and families; father engagement in urban settings; social factors affecting health and education; children of incarcerated parents; and intergenerational learning. Gadsden serves or has served on numerous foundation boards, congressionally mandated committees, and White House initiatives. A past president of the American Educational Research Association, she has held leadership roles in the Society for Research in Child Development and editorship of several publications, including Educational Researcher and the Review of Research in Education.
Petra Todd is the Edmund J. and Louise W. Kahn Term Professor of Economics in the School of Arts & Sciences. She is also a research associate of Penn’s Population Studies Center. Her main fields of research are social program evaluation, labor economics, and microeconometrics. She is on the editorial board of the International Economic Review and the Econometrics Journal. She is a fellow of the Econometrics Society and of the Society of Labor Economists. She has published papers on econometric methods for evaluating the effects of program/policy interventions, the determinants of cognitive achievement, testing for discrimination in motor vehicle searches, sources of racial and gender labor market disparities, pension program design, and on conditional cash transfer programs. She is currently working on projects analyzing the effects of personality traits on gender labor market disparities, evaluating the effects of grade retention in Portugal, analyzing the effects of local minimum wage policies in the United States, and analyzing the effects of a nationwide preschool reform in Mexico.
E. John Wherry is the Barbara and Richard Schiffrin President’s Distinguished Professor and chair of the Department of Systems Pharmacology and Translational Therapeutics in the Perelman School of Medicine and director of the Penn Institute for Immunology. Wherry has received numerous honors including the Distinguished Alumni award from Thomas Jefferson University and the Cancer Research Institute’s Frederick W. Alt Award for New Discoveries in Immunology. Wherry helped pioneer the field of T cell exhaustion, the mechanisms by which T cell responses are attenuated during chronic infections and cancer. He helped identify the role of the “checkpoint” molecule PD-1 and others for reinvigoration of exhausted T cells in cancer. Wherry’s work has defined the underlying molecular and epigenetic mechanisms of exhausted T cells. In 2020-21, his laboratory focused on the immunology of COVID-19 and SARS-CoV-2 vaccination including establishing a new Immune Health Project to interrogate and use immune features to identify novel treatment opportunities.
Nanoparticle blueprints reveal path to smarter medicines
New research involving Penn Engineering shows detailed variation in lipid nanoparticle size, shape, and internal structure, and finds that such factors correlate with how well they deliver therapeutic cargo to a particular destination.
A generous gift from alumni Glenn and Amanda Fuhrman brings the work of internationally acclaimed artist Jaume Plensa to the University of Pennsylvania. The latest addition to the Penn Art Collection expands Philadelphia's public art.
A massive chunk of ice, a new laser, and new information on sea-level rise
For nearly a decade, Leigh Stearns and collaborators aimed a laser scanner system at Greenland’s Helheim Glacier. Their long-running survey reveals that Helheim’s massive calving events don’t behave the way scientists once thought, reframing how ice loss contributes to sea-level rise.
