About
I am a Third year Ph.D. student and chancellor fellow in the Department of Computer Science at the University of California, Santa Barbara. I am very fortunate to be advised by Prof Prabhanjan Ananth. My research interests lie in quantum computing and quantum information. My recent work has been on quantum pseudorandomness and other primitives in Microcrypt.
Before joining UCSB, I obtained my BS in Mathematics from the Indian Institute of Technology, Kanpur in 2021. There I worked with Prof Rajat Mittal on polynomial over integers modulo prime powers and p-orderings. I also spent a semester at UCSB, working with Prof Trinabh Gupta on two-party schemes to create a private ML system, and a semester working with Prof Amit Kuber in co-operative games.
