Doctoral Student

In a nutshell ...

Since October 2016, I am a PhD student with Peter Druschel and Deepak Garg. I am part of the Distributed Systems and the Security & Privacy research groups. I am interested in designing and building computer systems that are secure, highly-available and privacy-preserving.
