Professor
Jonathan Heckman is a Professor in the Department of Physics and Astronomy at the University of Pennsylvania, part of the College of Arts & Sciences. His academic career includes roles as Associate Professor (2020–2025) and Assistant Professor (2017–2020) at Penn, and earlier as an Assistant Professor at UNC Chapel Hill (2014–2017). He holds a Ph.D. in Physics from Harvard University (2009), an A.M. from Harvard (2005), and an A.B. from Princeton University (2004). His research focuses on theoretical high energy physics, addressing foundational questions such as the nature of quantum field theory (QFT), the building blocks of spacetime and matter, and the unification of quantum theory with gravity via string theory. Key areas include: (1) QFT in extra dimensions, (2) F-theory compactifications and their phenomenological implications, and (3) UV cutoffs in string theory. Recent work emphasizes non-invertible symmetries, holographic dualities, and swampland conjectures. He teaches advanced courses like Relativistic Quantum Field Theory (Physics 6632) and Introduction to Field Theory (Physics 6601), as well as introductory mechanics (Physics 0140/0150). His publications span topics from 6D superconformal field theories (SCFTs) to dark energy models and collider phenomenology of string-inspired scenarios. Notable contributions include frameworks for analyzing F-theory compactifications, studies of generalized symmetries in non-supersymmetric string backgrounds, and explorations of string theory’s implications for cosmology and particle physics. His work bridges formal string theory developments with experimental testability, particularly through collider signatures and cosmological observations.
