I am a staff engineer at Google, where I work on using formal methods for privacy preserving AI. Until recently, I was working as part of the exciting Swift for TensorFlow project. Previously, I led a team that develops static analysis tools to improve the security of Android Apps. Before that I was an engineer at Facebook, and a research staff member in the Systems Analysis and Verification (SAV) group at NEC Laboratories America, Inc. I got my Ph.D in from the University of Wisconsin-Madison.
