About
Previously, I received my PhD in statistics from the University of Pennsylvania, advised by Edward George and Veronika Rockova.
My research develops flexible Bayesian models for analyzing high-dimensional data. Some of my recent research interests include:
- developing identifiable and interpretable deep generative models (especially variational autoencoders)
- improved tools for Bayesian model criticism
