I am an Assistant Professor of Biomedical Data Science and, by courtesy, of Computer Science and Electrical Engineering at Stanford University. I work on a wide range of problems in machine learning (from proving mathematical properties to building large-scale algorithms) and am especially interested in applications in biotech and health. I received a Ph.D from Harvard in 2014, and was at one time a member of Microsoft Research, a Gates Scholar at the University of Cambridge and a Simons fellow at U.C. Berkeley. I joined Stanford in 2016 and am excited to be an inaugural Chan-Zuckerberg Investigator and the faculty director of the AI for Health program. We are also a part of the Stanford AI Lab. My research is supported by the NSF CAREER Award, and the Google and Tencent AI awards.
