Post-doctoral Research Fellow - Cornell

lastname@cornell.edu

I am currently a post-doctoral research fellow at Cornell University working with Prof. Vitaly Shmatikov. I received my PhD degree in Computer and Communication Sciences from EPFL, Switzerland in 2013. There I worked with Prof. Jean-Pierre Hubaux. I also spent one year as a post-doctoral researcher at the Institute of Information Security, ETH Zurich, working with Prof. Srdjan Capkun. Here is my curriculum vitae.

My research focuses on Computational Privacy. I am currently involved in the following events:
