About Me

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

I am on the academic job market during the 2019-20 academic year.

Research

I am broadly interested in computer networking with special focus on datacenter networking.

My research focusses on designing next-generation datacenter networks in light of slowdown in performance scaling of CPUs and packet switches and exponentially rising bandwidth demand within datacenters. To that end, I design domain-specific hardware architectures to scale and improve the network stack processing and circuit-switched network designs to scale and improve the network switching fabric.

My research adopts a holistic approach to network design, concentrating on every layer of the network stack, ranging from the design of low-level physical hardware to higher-level algorithms and protocols, while cutting across multiple disciplines including networking, architecture, systems, and theory.
