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 in mathematical statistics usually involves interactions between probability, statistics, and geometry. Some specific topics I'm interested in include: clustering, empirical Bayes, Fréchet means, information geometry, optimal transport, and Riemannian optimization.
Selected works:
- Wasserstein-Cramér-Rao theory of unbiased estimation
with Nicolás García Trillos and Bodhisattva Sen
- Nonparametric Riemannian empirical Bayes, denoising measurements on manifolds with Leonardo Santoro and Bodhisattva Sen
- Asymptotic theory of geometric and adaptive \(k\)-means clustering
- Limit theorems for Fréchet mean sets with Steve Evans
