I am a PhD student in the Theory Group at UC Berkeley, fortunate to be advised by Prasad Raghavendra. Most recently, I have been thinking about problems to understand the power and limitations of semidefinite programming for average case problems. More generally, I am interested in random matrix theory, combinatorics, and geometry of polynomials. My undergraduate education was at Carnegie Mellon University where I had the fortune of being advised by Ryan O'Donnell on my senior thesis. I am also grateful for the mentorship of Anil Ada, Bernhard Haeupler, Ariel Procaccia, and David Woodruff during my time at CMU.
