Background
Currently a William H. Kruskal Instructor in the Department of Statistics at the University of Chicago
Research focuses on: Hierarchical Models (Identifiability, Statistical Efficiency, and Model Selection Methods), Statistical Genetics, Population Genetics, Phylogenetics, and Statistical Optimal Transport
Studies identifiability and parameter estimation for latent variable models (e.g., mixture and admixture models with unknown numbers of components) using optimal transport, empirical process theory, and Bayesian asymptotic theory
Develops interpretable and computationally efficient hierarchical Bayesian methods with applications in genetics
Starting Summer 2025, will work on GWAS with a focus on fine-mapping
