I received my Ph.D. degree in Traffic Information Engineering and Control from Beihang University, Beijing, China, supervised by Prof. Yunpeng Wang and Prof. Guangquan Lu. From 2016 to 2017, I was a Research & Development Engineer with the Quanzhou Institute of Equipment Manufacturing, Haixi Institutes, Chinese Academy of Sciences, led by Prof. Hao Chen. From 2020 to 2021, I was a Standard & Strategy Engineer at ZTE Corporation. Currently, I am a Research Scientist at Shanghai Artificial Intelligence Laboratory.

I have already published more than 40 academic papers in peer-reviewed journals and conferences (including 1 ESI Top 1% highly cited paper), obtained more than 10 patents, and 1 software copyright. I am also the reviewer of more than 50 journals and conferences. I participate in writing books of Urban Transport System Operation Reliability Analysis Method and Intelligent Road Transport Systems: An Introduction to Key Technologies. I also participated in the preparation of the Data Compliance Guidelines for Intelligent Connected Vehicles, which was released at the 2022 World Artificial Intelligence Conference (WAIC). I am the winner of the Yangfan Special Project of the Shanghai Qimingxing Program.

My research interests include multimodal large model, knowledge-driven inference, and cooperative vehicle infrastructure system.
