My name is Chao Yu（于超）. I received my Ph.D. from the Department of Electronic Engineering at Tsinghua University in 2023. I am currently an Assistant Professor (Distinguished Research Fellow) at the Embodied Decision Intelligence Lab (EDI Lab) at Tsinghua Shenzhen International Graduate School (SIGS). I also serve as the chairman of the Tsinghua Shenzhen International Graduate School - AgiBot Joint Research Center for Embodied Cognition and Decision Systems (JCES) 清华-智元联合研究中⼼主任. I’m also the co-founder of Striding AI(正行创新). I have been selected for the Youth Talent Support Program of the Chinese Institute of Electronics. My research has long focused on reinforcement learning–based decision intelligence. As first author or corresponding author, I have published more than 50 papers in top-tier international conferences and journals, including ICML, NeurIPS, ICLR, CVPR, ECCV, CoRL, IROS, ICRA, TMLR, and RAL, with over 7,000 citations on Google Scholar. My representative works include the multi-agent reinforcement learning algorithm MAPPO, which has received more than 4,000 Google Scholar citations, and RLinf, a large-scale reinforcement learning training framework for embodied intelligence, which has accumulated over 4,000 GitHub stars.

Feel free to reach out if you’d like to discuss research or explore potential collaboration!
