I am a research scientist at Google Brain. I am broadly interested in advancing science and intelligence, and where the ideas involve probability, programs, and/or neural nets.
At Google, I lead a team advancing uncertainty and out-of-distribution robustness in deep learning. Infrastructure I've worked on includes Uncertainty Baselines, Robustness Metrics, Edward2, TensorFlow Probability, Mesh TensorFlow, and Tensor2Tensor. Previously, I was a Ph.D. student at Columbia advised by David Blei and Andrew Gelman. I developed the original Edward language and was a member of the Stan development team.
