I am a PhD student in the Theory Group at UC Berkeley, advised by Jelani Nelson. My research interests lie broadly in design and analysis of algorithms.

I was a graduate student in the Theory of Computation group at Harvard, before moving to Berkeley with my advisor. Prior to that, I received my B.S. in Computer Science and in Mathematics from Duke University, where I had the fortune of working with Rong Ge and Debmalya Panigrahi.
