I am a Miller fellow in the theory group at UC Berkeley, where I am hosted by Prasad Raghavendra and Luca Trevisan. Before that, I got my PhD at Cornell, advised by David Steurer.
In the 2021-2022 academic year I will join MIT as an Assistant Professor in the Department of Electrical Engineering and Computer Science.
