About


I am a postdoctoral research scientist at the Columbia Data Science Institute, working with David Blei.

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
