I'm a fourth year Ph. D. student at the College of Computing, Georgia Institute of Technology. I work in the Networking and Telecommunications group with Prof. Nick Feamster.

I completed my undergrad at the Indian Institute of Technology Madras (Chennai, India), in the Department of Computer Science and Engineering. I'm interested in researching all aspects of Computer Networks including Protocols, Security and the Internet Architecture in general.

Research Interests

My current research focuses mostly on Network Security: techniques to detect and mitigate malicious activity on the Internet such as spam, botnets etc., with the eventual goal of designing practical, deployable systems to detect and counter such attacks.
