I'm an assistant professor of Computer and Information Science at Penn and a senior researcher at Microsoft Research.
At Penn, I'm part of the Distributed Systems Laboratory, the Security Research Laboratory, and The Warren Center for Network and Data Sciences. I'm the recipient of an NSF CAREER Award, a JPMorgan Faculty Award, the ACM SIGOPS Dennis M. Ritchie Dissertation Award, and the Bert Kay Best Dissertation Award.
I'm broadly interested in systems, security, privacy, and networking. My work aims to:
- Understand how the systems that we use today unintentionally leak information.
- Propose alternatives to existing services that provide strong privacy and integrity guarantees.
- Build abstractions and frameworks that simplify the development of concurrent and fault-tolerant applications.
- Specialize applications to run efficiently on new cloud architectures.
