About me

I am currently an Assistant Professor at the Centre for Artificial Intelligence and Robotics, Hong Kong Institute of Science & Innovation, Chinese Academy of Sciences, working with Prof. Zhaoxiang Zhang. I received my Ph.D. in Pattern Recognition and Intelligent Systems from the Institute of Automation, Chinese Academy of Sciences, where I was advised by Prof. Cheng-Lin Liu and Prof. Xu-Yao Zhang. Prior to this, I received the B.E. degree from Tsinghua University.

Research Highlights: My research interests include topics in reliability (e.g., uncertainty estimation and calibration, failure detection) and adaptability (e.g., continual learning, novel class discovery) of mechine learning models (especially foundation models such as LVMs, LLMs and MLMs）in the open world/environment applications.

I am actively seeking highly motivated students. If you are interested, please send me an email with your CV.
