About Me

I am a Research Scientist at Beijing Institute for General Artificial Intelligence (BIGAI). I received my Ph.D. in the Department of Statistics at the University of California, Los Angeles (UCLA). I believe the ability to comprehensively perceive the world is central to next-step general AI. Thus, my research focuses on enabling human-like vision capabilities for machines, particularly in the areas of 3D scene understanding, e.g., reconstruction, grounding, human motion and human-object interaction.

Previously, I interned at Perceiving Systems, MPI for Intelligent Systems advised by Prof. Michael Black and Prof. Dimitrios Tzionas, and Amazon supervised by Li Erran Li.
