I'm a PhD student in the Center for Theoretical Neuroscience at Columbia University, advised by Ashok Litwin-Kumar. I'm interested in a variety of topics in machine learning and neuroscience, including reinforcement learning, meta-learning, memory systems, deep learning theory, and model interpretability. I graduated from Stanford in 2019 with degrees 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.
