I am a postdoctoral researcher at Princeton’s computer science department and a visiting researcher at the Institute for Advanced Study’s math department—both as part of the Simons Collaboration on Algorithms and Geometry. In the fall, I will start as a postdoctoral researcher at MIT supervised by Vinod Vaikuntanathan. My research to date has focused on lattices, but I am also interested in theoretical computer science and cryptography more broadly.

I received my PhD from NYU’s Courant Institute, advised by Professors Oded Regev and Yevgeniy Dodis.
