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 interactions between probability, statistics, and geometry. Some specific topics I'm interested in include: clustering, dimensionality reduction, empirical Bayes, Fréchet means, information geometry, optimal transport, and Riemannian optimization.
Selected publications:
- Asymptotic theory of geometric and adaptive \(k\)-means clustering. Annals of Statistics. 53(4): 1559-1586.
- Limit theorems for Fréchet mean sets with Steve N. Evans. Bernoulli. 30(1), 419-447.
- A strong duality principle for equivalence couplings and total variation. Electronic Journal of Probability. 28, 1-33
