Zhen ZHAO (赵振) has been with the OpenEarthLab at the Shanghai AI Laboratory, and the New Power System Research Center at the Huairou Laboratory, as a Researcher, since June 2024. Dr. ZHAO obtained his Ph.D. from the School of Electrical and Computer Engineering, the University of Sydney (USYD), under the supervision of Prof. Luping Zhou and Prof. Wanli Ouyang from the USYD and Prof. Lei Wang from the University of Wollongong. His research interests include exploring semi/self-supervised learning techniques for label-efficient perception and developing multimodal foundation models for reasoning & decision-making tasks. Most recently, he focuses on AI for science, especially grid state estimation, trustworthy energy operations, and visual reconstructions from brain activity.

Prospective Interns:

1) senior students in heterogeneous graph learning / graph foundation models for solving power/energy related issues from the data-driven perspective. 2) self-motivated junior students, who may seek the oppotunitity of Joint Training Ph.D. Project, supervised by Prof. Lei Bai.
