Chinmay Nirkhe

Biography

Staring Summer 2024, I am a faculty member in the Allen School of Computer Science and Engineering and a member of the CS Theory group. Before UW, I was a research scientist with IBM Quantum. I received my Ph.D. from Berkeley and my B.S. from Caltech.

My research is at the intersection of complexity theory and quantum computation. In particular, I am interested in proving hardness-of-approximation results and lower bounds on the description complexity of quantum states.

Graduate Students

None yet! If you are interested in being advised by me or collaborating with me, send me an email listing problems you are interested in and your background. I'm more interested in students who have demonstrated an ability to pick up new skills and have a desire to tackle big problems than a particular background in complexity theory or quantum computation.
