Hans Hao-Hsun Hsu

Hi, my name is Hans Hao-Hsun Hsu. I am a Machine Learning PhD student at Georgia Tech working with Pan Li. I am also an intern at Lawrence Berkeley National Laboratory (LBNL), where I work closely with Benjamin N. Erichson. My current research interests lie in generative models for modeling complex dynamics and their applications to world models.

Previously, I also worked on trustworthy AI on graphs and agents (reliability, robustness and explainability). Prior to Georgia Tech, I was a machine learning researcher at Celeris Therapeutics, a UK-based startup, working on PROTAC-related drug discovery. I obtained my M.S. degree (with high distinction) from the Technical University of Munich advised by Daniel Cremers. I also hold a B.S. degree from National Taiwan University.

Feel free to reach out to me for any collaboration or research opportunities.
