Biography

Currently, I am working at the Shanghai AI lab as a research fellow. I got Ph.D. degree from Shanghai Jiao Tong University. I was supervised by Prof. Quanshi Zhang at John Hopcroft Center for Computer Science. Before that, I received my B.Sc. degree from Northeastern University.

Research Interests

My research interests include topics in machine learning. Most recently, I am interested in the explainability and safety of multi-modal foundation models and 3D point cloud processing. We are looking for cooperation and research interns to work together on the safety/robustness/explainability of foundation models. Please drop me an email liudongrui@pjlab.org.cn if you are interested.
