I am a 3rd year PhD student in the Mathematics Department at Princeton University. My advisor is Igor Rodnianski.

My research interests are partial differential equations, general relativity, and nonlinear wave equations. I am currently working on self similar solutions of the Einstein vacuum equations. I am also interested in the weak cosmic censorship conjecture and examples of naked singularities.
