About me

I am an NSF Computing Innovation Fellow and Assistant Research Scientist at the Dept. of Computer Science, Johns Hopkins University. My research is currently supported by the 2009 NSF/CRA Computing Innovation Postdoctoral Fellowship. At Hopkins, I collaborate with Prof. Randal Burns.

I received my Ph.D. in Computer Science in October 2009, from University of  Illinois at Urbana-Champaign. My advisor was Prof. Marianne Winslett. I was also co-advised by Prof. Radu Sion of SUNY-StonyBrook.

I am primarily interested in Cloud Computing, Computer Security, Secure Provenance, Trustworthy Databases and File Systems. My PhD dissertation topic is related to protecting the past (secure provenance,) and present (term-immutability) of data.

In Spring 2010, I am teaching the graduate level course CS 600.412 "Security and Privacy in Cloud Computing" at Johns Hopkins.
