About

I am an Associate Professor and Ph.D. supervisor in the School of Computer Science and Engineering at Northeastern University, China. I received my Ph.D. in Engineering from the University of Chinese Academy of Sciences in June 2025 and was a visiting scholar at the National University of Singapore. My research interests include multimodal large models, image and video understanding, and embodied intelligence. I received the President's Award of the Chinese Academy of Sciences, the CAS ZhuLi Yuehua Award, the 3DMM Best Student Paper Award, and the ChinaMM Best Poster Award. I am a member of the Cloud-Network Intelligent Computing Group.

Openings: I have openings for Ph.D. students (1-2/year), Master's students (4-6/year), and undergraduate interns. If interested, please email me.
