I am a Postdoctoral Researcher in statistics at
Columbia University, working under the supervision of
Bodhisattva Sen.
Previously, I received my PhD in statistics from
UC Berkeley
and my BS in mathematics from Stanford.

My research focuses on the interplay between statistics and geometry, including topics like clustering, empirical Bayes, Fréchet means, and optimal transport. I am interested both in fundamental questions in mathematical statistics and in new mathematical statistics questions arising in applications, e.g., astronomy, baseball analytics, and computational biology.
