About Me

I am a Ph.D. student in the Department of Computer Science at Cornell University. I am advised by Prof. Hakim Weatherspoon. I received an M.S. in Computer Science from Cornell University in 2017. Prior to Cornell, I was an undergraduate student at Indian Institute of Technology, Kharagpur.


I am broadly interested in Computer Networking. My research is driven by the critical implications of slowdown in Moore's law and the end of Dennard scaling, resulting in an ever-increasing gap between the processing & switching capacities and the bandwidth demand within datacenters. My research tries to bridge this gap by efficiently leveraging custom hardware for networking, such as domain-specific processors for network processing and circuit switches for data switching. To that end, my research integrates the domains of Computer Networking and Computer Architecture, by proposing generic and programmable primitives for network processing and switching, and designing efficent hardware architectures for those primitives. Further, my research also focusses on designing novel network stack, protocols, and algorithms that efficiently leverage custom networking hardware for high performance.

My projects fall under two broad research agendas:

Designing generic and programmable network primitives and mapping them to efficient hardware architectures

Designing network stack, protocols, and algorithms that efficiently leverage underlying network hardware
