I am a postdoctoral researcher at the UCSB Computer Science Department and currently visiting University of Chicago, Department of Computer Science. I am a member of SAND lab and work with Prof. Ben Y. Zhao. Previously, I worked as a researcher at Nokia Bell Labs, Stuttgart for a year. I completed my Ph.D. in Computer Science at the Max Planck Institute for Software Systems where I was advised by Prof. Krishna P. Gummadi and Prof. Alan Mislove. As a PhD student, I also spent summers at MSR India, MSR Redmond, and Northeastern University.

I am broadly interested in systems security and privacy, as well as data mining and machine learning.
