About

I’m a theoretical physicist working on the fundamental laws of Nature. My research focuses on understanding how light, matter, and the space-time metric interacting at the quantum level can be probed through scattering processes. I’m particularly interested in applications of modern mathematical and computational techniques from algebraic geometry and machine learning to aid our understanding of such physical questions. Recently, I’ve been working on applying these tools to gain new insights into the physics of heavy astrophysical objects, such as neutron stars or black holes. Outside of research, I’m an avid fan of vexillology, the Oxford comma, and self-referential humor.

I’m an assistant professor at the Department of Physics at Columbia University in the City of New York. I previously held various positions including that of a postdoctoral fellow and lecturer at Princeton University, an affiliated postdoctoral fellow at the Princeton Center for Theoretical Science, and a long-term member at the Institute for Advanced Study. I received my PhD under the supervision of Freddy Cachazo at the Perimeter Institute for Theoretical Physics and the University of Waterloo and obtained undergraduate degrees in natural sciences and mathematics from the University of Cambridge.
