About Me

I am a Postdoctoral fellow at ICSI, Berkeley, where I am part of the BLUES group working with Serge Egelman. I obtained my Ph.D. in Computer Science from the Khoury College of Computer Sciences at Northeastern University, where I was advised by Christo Wilson. Prior to that, I worked with Krishna Gummadi at Max Planck Institute for Software Systems.

My current research focuses on the web/mobile security & privacy. In particular, I am studying the online advertising ecosystem on the web to understand how it impacts users' privacy. My goal is to make the online advertising ecosystem more transparent to enable users make informed decisions regarding their personal information. I have previously worked on projects aimed at limiting abuse on online services such as Facebook and Twitter.
