I am an Assistant Professor in the UCSD CSE Department. I am also the Chief Scientist at Intrinsic (formerly GitStar), a web security start-up I co-founded. My research interests are in building principled and practical secure systems. More broadly, I am interested in research that spans systems, security, and programming languages. I work on several systems, including COWL, a browser confinement system designed for modern web applications, Hails, a security-centric framework for building web platforms, LIO, a dynamic information flow control system, and ESpectro, a security architecture for Node.js. At Intrinsic, I am putting much of this research into practice by building systems, tools, and languages that ultimately make it easier for developers to build and deploy web applications with minimal trust.
