Short Bio

I am an assistant professor (ZJU-100 Young Professor) at Zhejiang University. I received my Ph.D. degree from College of Computer Science and Technology at Zhejiang University in 2023, supervised by Prof. Xiaowei Zhou and Prof. Hujun Bao, and obtained my bachelor degree in Information Engineering from Zhejiang University in 2018. I received the 2024 CCF Outstanding Doctoral Dissertation Award and was selected as the 2022 Apple Scholar in AI/ML. I have been maintaining a handbook on learning research, which have received more than 6800 stars on GitHub.

I work closely with Prof. Xiaowei Zhou. We are looking for students, postdocs and research assistants. Please apply to our lab here if you are interested in working with us.

Research Summary

I like advancing Visual Effects and Autonomous Driving, as well as solving fundamental research problems arising from important challenges. I also like to explore the capability boundaries of new techniques on addressing challenges.

After the CVPR 2025 submission, I decided to pursue research projects that address crucial problems in the industry with significant impact. Such problems typically lack well-established solutions, necessitating us to explore new techniques and provide new insights. I would avoid participating in projects that lack both practical value and unresolved problems, as I believe they only produces useless papers, consuming my passion for research.

The following are my target systems:

Volumetric Video
Driving Simulator
Egocentric AI
