Assistant Professor

My current research focuses on building secure systems, all the way from hardware to system software to applications that run on them.

We have designed and built the first secure processor that obfuscates all digital signal outputs, including even addresses to physical memory. This processor, implemented on a Convey FPGA-based server, can be used as a root of trust in datacenters where an attacker (a malicious employee, for example) has physical access to confidential computation.

We are also working on a platform where users can control their privacy while using applications that span mobile and datacenter machines. We have prototyped an OS-level mandatory access control system that enforces policies across Android and server-side Linux machines, and developed a simple design pattern to express rich functionality in privacy preserving applications.

I received a PhD from UC Santa Barbara (2011) and was a post-doctoral fellow at UC Berkeley (2011--13) before joining UT.
