I work at Anthropic on mechanistic interpretability of deep learning models. Previously, I did my PhD in the Center for Theoretical Neuroscience at Columbia University, advised by Ashok Litwin-Kumar, and my undergrad at Stanford in math and computer science. I've also worked on neuromotor interfaces at Meta, neuromorphic computing at Sandia National Labs, and optimizations for deep learning hardware at Cerebras Systems. I'm interested in a variety of topics in machine learning and neuroscience, including model interpretability, reinforcement learning, meta-learning, memory systems, and deep learning theory.
