Assistant Professor at Zhongguancun Academy

Xingyu Chen

I lead ZGCA HMI Lab, working on Interaction-centric Embodied AI.

I am currently an Assistant Professor at Zhongguancun Academy. Previously, I was an assistant research fellow at Peking University, working closely with Prof. Lei Zhang at IDEA-CVR.

Before joining PKU, I spent 4 years in industry at Kuaishou and Xiaobing, working closely with Dr. Baoyaun Wang. I received my Ph.D. from the Institute of Automation, Chinese Academy of Sciences in 2020 under Prof. Junzhi Yu, and my B.S. from Chengdu University of Technology in 2015.
