Welcome to my homepage. I am work at Google leading the effort to bring code completion, code generation and code chat via Gemini Code Assist. Previously, I was leading an effort in the applied research team at Facebook AI on computer vision, multimodal understanding and continual learning. Prior to this, I spent seven and a half years at HeartFlow developing physics-driven and AI based techniques for treatment and diagnosis of heart disease. I received my PhD at Cornell University and spent several more years doing research at UCSD and Stanford University. This page is intended to disseminate my work in academia and industry.
