I am a 4th year Ph.D student advised by Andreas Haeberlen.


I am interested in distributed systems, privacy and security. I work on Differential Privacy with the Privacy Group. In summer 2013 I was away at Microsoft Research on an internship working with Jon Howell, Chris Hawblitzel, Bryan Parno, and Jay Lorch.

In Fall 2011 I was a Teaching Assistant for MKSE 212: Scalable and Cloud Computing.
In Spring 2012 I was a TA for CIS 455/555: Internet and Web Systems.


My personal blog is here. I don't blog much about computer science though.


If you're a Williams student thinking about applying to CS grad schools, feel free to get in touch! I can't guarantee to be helpful, but I can guarantee to be more helpful than this guy. (This other guy is trying to get in on our reciprocal link scheme, but don't trust him.)
