I recently completed my M.S. in Data Science at the University of Chicago, where I was fortunate to be advised by Prof. Haifeng Xu. Before Chicago, I earned my B.A. in Computer Science and Mathematics at New York University.

My research interests lie in generative modeling, reasoning and post-training, and mechanistic interpretability of large language models.
