Fangzhou Wu

I'm a third-year Ph.D. student at University of Wisconsin–Madison, where I am fortunate to be co-advised by Kristin Eschenfelder and Sandeep Silwal. Prior to coming to Madison, I earned my bachelor's degree from Huazhong University of Science and Technology (HUST).

Research

I am broadly interested in developing provably efficient algorithms to accelerate training and inference for foundation models and agents. My research aims to bridge theoretical insights and practical system design by integrating these algorithms into modern foundation-model-based applications.
