I'm an assistant professor of Computer and Information Science at UPenn, and I'm part of the Distributed Systems Laboratory and The Warren Center for Network and Data Sciences. I also run Penn's security reading group. Prior to joining Penn, I was a visiting academic at NYU's Courant Institute of Mathematical Sciences, and spent a lot of time working with amazing folks at Microsoft Research in the Cambridge, Redmond, and New York City labs.

My work studies different aspects of systems, security, privacy, and networking. I'm particularly interested in:

Understanding how the systems that we use today unintentionally leak information.
Building the next generation of anonymous and censorship-resistant communication systems.
Building tools to help developers incorporate advanced cryptographic primitives into their applications.
Making concurrent programming easier for developers.
