About me

I am currently a Professor, Nanjing University. I was a research scientist in the Department of Electrical and Computer Engineering, New York University Abu Dhabi and New York University Tandon School of Engineering. I did my Ph.D study in the Department of Computing, Hong Kong Polytechnic University, under the supervision of Prof. Lei Zhang. Here is my full CV.

I am always looking for self-motivated and talent undergraduate/master/Ph.D students to work with me. I am also recruiting postdocs to join our team.

Research

I mainly focus on 3D computer vision and its applications on autonomous driving and robotic manipulation, which lie at the intersection of machine learning, computer vision, computer graphics and robotics. My research goal aims to enable robotics to automatically perceive, understand, simulate 3D physical world and interact with 3D physical world from images, videos and point clouds. Specifically, my research interests fall into 3D low-level imaging, 2D/3D scene understanding, 3D object navigation and planning, 2D/3D object and scene generation, 6D pose estimation and grasping for interaction, etc. I am also interested in vision foundation models and generative models. My recent focus includes:

  • 3D scene understanding lifted with 2D vision foundation models and large language models

  • 3D object and scene generation with physical simulation in autonomous driving and robotics

  • Large language models guided object navigation and planning.
