I am a PhD candidate at the University of New Mexico in the Physics and Astronomy department advised by Ojas Parekh, Principal Member of Technical Staff at Sandia National Laboratories. I am also part of the Center for Quantum Information & Control (CQuIC). My broad research interests are in the field of Quantum Computing and Quantum Information Science. Currently, I am working on problems in Hamiltonian complexity and approximation algorithms for quantum problems.
I received my undergraduate and master’s education at the Indian Institute of Technology (IIT), Madras in Electrical Engineering with a minor in Physics. For my master’s thesis, I worked on designing quantum error-correcting codes using good classical error-correcting codes, and was advised by Pradeep Kiran Sarvepalli.
Before starting my PhD, I worked as a software engineer at Texas Instruments in Bangalore, India.
