About me
Hi, Welcome to my home page ! I am a PhD student in the department of Computer Science and
Engineering at the Ohio State University.
My advisor is
Dr. Dhabaleswar K Panda and I work in Network-Based Computing
Research Group.
I got my bachelors in Computer Science and Engineering from IIT-Madras, India.
I am currently looking for a challenging position as a Research Staff Member.

Research Interests
My research focus is the area of Communication Architecture in the High Peformance Computing domain.
This includes diverse topics such as:
- Communication Algorithms and optimizations for multi-core architectures
- User Level Protocols over Connection-Oriented and Connection-Less transports
(e.g. InfiniBand)
- High-Performance Cluster Interconnects
I work on MVAPICH project which is an open source
distribution of MPI over InfiniBand.
My current focus is on designing a scalable and efficient collective communication subsystem for MVAPICH.
