I'm an assistant professor of Computer and Information Science at Penn where I'm part of the Distributed Systems Laboratory, the Security and Privacy 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 was previously a senior researcher at Microsoft Research.
I'm broadly interested in systems, security, privacy, and networking. My work aims to:
- Build the next generation of privacy-preserving systems, from messasing apps to online advertising.
- Bring accountability to online services by forcing these service to prove that they are doing the right thing.
- Build abstractions and frameworks that simplify the development of concurrent and fault-tolerant applications.
Open Position Vincent Liu and I are looking for a postdoctoral researcher to help us reimagine the next generation of serverless technology. This is a large collaboration funded by the NSF in partnership with Princeton, Stony Brook, and University at Buffalo. Please take a look at our prior work in this area: Beldi and mu2sls.
