Chaithanya Rayudu

I am a PhD candidate at the University of New Mexico in the Physics and Astronomy department.

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

I am on the job market for a postdoc or industry position starting in 2026.
