Hi! I am a Postdoctoral Fellow working in the Center for Particle Cosmology, part of the University of Pennsylvania. Previously I was a PhD student at the Department of Applied Mathematics and Theoretical Physics (DAMTP), University of Cambridge, and an undergraduate at Yale University.
I am interested in cosmology, and particularly its use to test theories of gravity beyond general relativity. Cosmology is the study of the origins, evolution, and fate of the Universe, and each of these is intimately bound up with the laws of gravity. Modified theories of gravity may be behind the puzzling fact that the expansion of the Universe is accelerating, rather than decelerating. I am especially interested in theories which can address this mystery, although I have worked on and continue to study more general models beyond general relativity. I have been interested in the conceptual and observational implications of massive gravity and its generalization, massive bigravity, and of late have been thinking about more general field theoretical questions inspired by modifying general relativity, and questions of effective field theories.
