About Me

I am an Assistant Professor of Electrical and Computer Engineering at Purdue University. My research interests are broadly in the areas of computer networking and networked systems. At Purdue, I co-found and co-lead the university-wide PurNET Lab.

I joined the faculty at Purdue University in January 2021, prior to which I was a Postdoctoral Associate (Sep 2020–Dec 2020) in the Department of Computer Science at Yale University. Earlier, I received a Ph.D. (2020) and an M.S. (2017) both in Computer Science from Cornell University. Even earlier, I received my undergraduate degree in Computer Science and Engineering from the Indian Institute of Technology (IIT), Kharagpur.

My work has been recognized with a National Science Foundation CAREER Award, a Google Research Scholar Award, and a Cisco Research Award. At Purdue, I have been awarded an Eta Kappa Nu (HKN) Outstanding Professor Award.

Research

I am a computer networking researcher who builds networked systems for real-world problems. My research adopts a full stack approach to designing computer networks and systems, ranging from low-level hardware design to designing higher-level system software and applications tailored to the hardware capabilities underneath. My current research is broadly focused on the following topics:

● High-speed, programmable network hardware
● [NSDI'24b, SIGCOMM'22a, SIGCOMM'22b, SIGCOMM'19, SOSR'17]
● In-network / network-accelerated computing
● [ASPLOS'25, NSDI'24a, DIDL'21, HotNets'21, ToN'19, SIGCOMM'16]
● Reconfigurable networks
● [HotNets'24, SIGCOMM'24, STOC'24, SIGCOMM'23, APOCS'23, STOC'22, NSDI'19]
● Networks + AI/ML
● [NSDI'24a, DIDL'21]
● Networks for disaggregated datacenter
● [ASPLOS'25, NSDI'19]
