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