Hello! I'm a researcher at Amazon AGI SF, where I currently work on reinforcement learning for web-browsing agents.
I completed my MS in EECS and BA in CS and Math at UC Berkeley,
where I had the pleasure of working on Machine Learning research under the mentorship of
Pieter Abbeel,
Youngwoon Lee, and
John Wawrzynek.

Research
I'm interested in deep learning in general, and RL for LLMs in particular. In the past, I've also worked on model-based RL and diffusion models.
