About Me

I am a physics PhD candidate at Harvard University. I am working with Prof. Ashvin Vishwanath on strongly correlated physics. In Fall 2024, I will visit KITP as a KITP Graduate Fellow. My interests lie in studying emergent phenomena in condensed matter systems analytically and numerically. In my spare time, I enjoy music, hiking, and reading.
