My research focuses on interactions between probability, statistics, and geometry. Some specific topics I'm interested in include: clustering, empirical Bayes, Fréchet means, optimal transport, Riemannian optimization, and statistical shape analysis.
Selected publications:
- Asymptotic theory of geometric and adaptive \(k\)-means clustering. Annals of Statistics (forthcoming).
- 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
