I'm a third-year Ph.D. student in the Future Data Systems group at Stanford University, advised by Peter Bailis. My research focuses on machine learning, with an emphasis on real-world applications. In particular, I'm interested in approximation techniques to accelerate learning and inference, approaches toward interpretable representation learning, and methods for weakly-supervised learning.

I received an MS in CS from Stanford in 2015. During my Master's, I was a member of the Stanford NLP Group. As an undergraduate, I studied Physics at Princeton University.
