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.

My research is focused on developing machine learning methods capable of handling diverse and heterogeneous data sources. In particular, I utilize and develop techniques in optimal transport, Bayesian nonparametric models, domain adaptation/generalization, and large model pretraining & fine-tuning. The ultimate goal of my work is to enable generalizable and reliable machine learning applications in critical sectors, such as healthcare and robotics.
