I'm a first-year PhD student in physics at Caltech, and am broadly interested in quantum information and fundamental physics, especially topics related to quantum complexity. Previously, I completed my bachelor's in physics and math at MIT, and wrote my senior thesis on the application of random circuits to study many-body quantum dynamics. You can find a summary of my research and teaching work here, or see my CV for a more complete list of things I've done.

I am committed to increasing access to opportunities in STEM, particularly for students from underrepresented backgrounds. I previously served on the MIT Physics Values Committee, and am also interested in designing better curriculum to support STEM education.
