I am currently a postdoctoral research associate at the Department of Physics at the University of Illinois, Urbana-Champaign.
From 2020-2022 I was a postdoctoral research associate at the Department of Applied Math and Theoretical Physics at the University of Cambridge.
In 2020, I obtained my PhD from the Department of Physics, Princeton University, under the supervision of Frans Pretorius. A pdf of my thesis, General Relativity and its classical modification in gravitational collapse, can be found here.

Broadly speaking my research has been in gravitational physics/astrophysics and computational physics. I have done work in numerical relativity, black hole ringdown, modified gravity, neutron star physics, and relativistic fluids. Much of my work has involved using a computer in one way or another, and I have spent some time developing new algorithms for use in numerical relativity.
A description of some of my work can be found here.
