Bowen Fang

I am a Ph.D. student at Columbia University , where I work with the Data Science Institute (Smart Cities Center). My research centers on understanding the behaviors behind post-training algorithms for large models, evaluating system resilience, and studying how agents can bootstrap meaningful search and competence in huge spaces with sparse signal and minimal useful prior structure.

I am a two-time Applied Scientist Intern at AWS AI , where my work centers on post-training for large models.

I hold an M.S. in Operations Research from Columbia University and a Bachelor in Big Data Management and Applications, minor in Economics from Peking University .

This website serves as a central hub for my publications, projects, and professional activities.
