I am a PhD Student in the Dept. of Computer Science & Engineering at the Ohio State University. I am currently working with Dr. Dhabaleswar K. Panda in the Network-Based Computing Lab.

My areas of interest include High Peformance Computer Networks, Network Based Computing, Internet Router and Switch Architectures.

Currently, I am working on the following projects:

Design of Scalable Data-Centers over InfiniBand and iWARP

Design and Evaluation of Communications Protocols over InfiniBand WAN

Design of High Performance MPI over iWARP

I earned my Bachelors degree in Computer Science and Engineering from the University of Kerala at the University College of Engineering, Trivandrum.
