I am a machine learning researcher based in San Francisco, working on reinforcement learning. At work, I focus mostly on model-based RL and learned planning. In my free time, I think a lot about test-time alignment of RL systems.
Selected papers
Besides my research, I like to think deeply about philosophy, history and culture and spend considerable time playing baseball and the violin.
Feel free to reach out if you are interested in any of my pursuits. I try to answer all emails I get.
