Jiacheng Zhu

I am a Ph.D. student at Carnegie Mellon University Safe AI Lab. I am fortunate to work under the supervision of Prof. Long Nguyen at UMich Statistics and Prof. Bo Li at UIUC CS.

I obtained a master's in Machine Learning from Carnegie Mellon University. Before that, I received my Bachelor's degree in Engineering Mechanics and a minor in Data Science from Fudan University.

Research

I am interested in machine learning problems on heterogeneous data sources. Specifically, I work on topics including optimal transport, Bayesian nonparametric models, and domain adaptation/generalization with applications to robotics, autonomous driving and healthcare.

A preliminary clustering analysis of my works:
