I am a research scientist at Google DeepMind.

I completed my Ph.D. at Berkeley EECS in 2024, advised by Jelani Nelson. During graduate school, I had also spent time at Simons Institute, Google Research and Berkeley AI Research. I received B.S. in Computer Science and B.S. in Mathematics from Duke University, where I had the fortune of working with Rong Ge and Debmalya Panigrahi.
