معرفی
Justin Khoury is the Edmund J. and Louise W. Kahn Term Professor of Physics and Astronomy at the University of Pennsylvania, affiliated with the School of Arts & Sciences and the Department of Physics and Astronomy. He also serves as Co-Director of the Penn Center for Particle Cosmology. His research focuses on the intersection of particle physics and cosmology, particularly exploring the dark sector, screening mechanisms (e.g., chameleon and symmetron fields), and alternative cosmological models like the Ekpyrotic Universe.
Education: Ph.D. in Physics from Princeton University (2002); B.Sc. in Physics from McGill University (1998).
Research Interests: Khoury investigates novel theories of the early universe, including alternatives to cosmic inflation. His work addresses dark matter interactions, gravitational screening mechanisms to reconcile theoretical predictions with experimental constraints, and the development of models that generate cosmological perturbations through contraction phases. Key themes include exploring light scalar fields evading solar system tests of gravity and refining the theoretical framework for cosmological structure formation.
Scientific Awards: Notable honors include the Buchalter Cosmology Prize (2017), Lindback Award for Distinguished Teaching (2019), and multiple grants (W. M. Keck Foundation, NSF CAREER Award). His work has been recognized for advancing theoretical cosmology and particle physics.
Grants & Advising: Khoury has secured funding for projects like the W. M. Keck Foundation Science and Engineering Grant (2017–2019) and the Charles E. Kaufman Foundation’s New Initiative Research Grant (2015–2017). His advising focuses on graduate students in theoretical cosmology and particle physics.
Labs & Collaborations: As Co-Director of the Penn Center for Particle Cosmology, he leads interdisciplinary efforts to bridge particle physics and cosmological observations, with active collaborations at institutions like the Perimeter Institute for Theoretical Physics.
