Yuchen Hu

Hi! I am a fifth-year Ph.D. student in the Department of Management Science and Engineering at Stanford University, advised by Dr. Stefan Wager. I am interested in a wide range of topics related to causal inference and data-driven decision-making.

I am on the 2024-2025 academic job market. A copy of my CV is available here.
