I am a Ph.D candidate at Brown University working with Professor Roberto Tamassia. I am interested in applied cryptography and computer security. My current research addresses the security and privacy of cloud storage and cloud applications with work on authenticated data structures, verifiable computation, efficient and zero-knowledge verification of queries on outsourced data, and data integrity protocols. My other interests include algorithms and data structures.

My research is supported in part by the U.S. National Science Foundation and by the Paris C. Kanellakis Fellowship at Brown University. I was supported by Coline M. Makepeace Fellowship for the academic year 2012-13.

Before joining Brown as a grad student, I completed my MS (by research) at the Theory group at IIT Madras in India under the guidance of Professor C. Pandu Rangan. My masters thesis was on Hamiltonicity and Longest Path Problem on Special Classes of Graphs. During my masters, I interned at the Distributed Systems group at Siemens Research under the mentorship of Mr. Subhas K. Ghosh and I worked on Independent Spanning Trees problem on Optical Transpose Interconnect System.

After finishing my masters, I was a Project Associate in the Fixed Parameter Algorithms group at IMSc, India between December 2011 and July 2012 and I was mentored by Dr. Saket Saurabh.


I am interning with the Cloud Storage and Security group at IBM Research Zurich from June - December 2016.

I spent the summer of 2015 interning in the Constructive Security group at Microsoft Research Cambridge.
