About
I am a PhD candidate in the Department of Electrical and Computer Engineering at the University of Maryland, College Park, advised by Prof Prakash Narayan. My recent work has been on shared information, a measure of mutual dependence among multiple random variables that has connections to data compression and information secrecy. I have explored applications of shared information to wireless networks and robot swarms. I have also applied insights from classical information theory to derive fundamental bounds on multiterminal quantum entanglement distillation. Previously, I have worked on analyzing the tradeoff between sampling and lossy compression in random fields.
Before joining UMD, I obtained my BTech in Electrical Engineering from the Indian Institute of Technology, Kanpur in 2019. There I worked with Prof Adrish Banerjee on classical coding theory bounds in discrete metrics. I also spent a summer at CUHK, working with Prof Sidharth Jaggi on adversarial channels, and a semester working with Prof Rajat Mittal on quantum query complexity.
I co-organize the Communication, Control and Signal Processing Seminar.
