I completed my PhD in 2026 in the Physics department at the University of New Mexico, where I was part of the Center for Quantum Information & Control (CQuIC). I was advised by Ojas Parekh from Sandia National Laboratories. My broad research interests are in the field of quantum computing and quantum information science.

I received my undergraduate and master’s education in Electrical Engineering, with a minor in Physics, at the Indian Institute of Technology (IIT) Madras. Before starting my PhD, I worked as a software engineer at Texas Instruments in Bangalore, India.
