Vishal Shrivastav — Purdue University

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 systems. I co-lead PurNET Lab. Prior to joining Purdue's faculty in January 2021, I was a Postdoctoral Associate (Sep–Dec 2020) in the Department of Computer Science at Yale University. I hold a Ph.D. (2020) and an M.S. (2017) both in Computer Science from Cornell University. Prior to Cornell, I was an undergraduate in the Department of Computer Science and Engineering at the Indian Institute of Technology (IIT), Kharagpur.

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

Prospective Students: If you are interested in working with me, please send me an email with your research interests and CV and apply to Purdue ECE Graduate Program (select Computer Engineering as the area of interest in your application).

I am broadly interested in computer networking and systems. My research adopts a holistic approach to designing computer networks and systems, ranging from low-level hardware design to designing higher-level protocols and applications that leverage the novel hardware underneath. My current research is centered around "network-accelerated computing" involving two broad themes — (i) designing high-speed and programmable architectures for network processors (switches, routers, NICs, FPGAs, middleboxes) [NSDI'24b, SIGCOMM'22a, SIGCOMM'22b, SIGCOMM'19, SOSR'17]; and (ii) leveraging emerging network hardware and technology to improve the design and performance of networked and distributed systems and applications, including – (a) ML-based systems and applications [NSDI'24a, DIDL'21]; (b) systems for resource disaggregation [FAST'24, NSDI'19]; (c) network functions and distributed protocols [HotNets'21, ToN'19, SIGCOMM'16]; and (d) reconfigurable network architectures [STOC'24, SIGCOMM'23, APOCS'23, STOC'22, NSDI'19].
