Chen Xiao-Ping is a professor in School of Computer Science and Technology at University of Science and Technology of China (USTC). He received a Ph.D. in Computer Science from USTC, a M.E. in Electrical Engineering and a B.A. in Mathematics from Anhui University. Prof. Chen is currently Director of the Center for Artificial Intelligence Research, USTC. He also serves as Trustee of the International RoboCup Federation, Member of Editorial Board of Journal of Artificial Intelligence Research, Member of Editorial Board of Knowledge Engineering Review, and Chair of the Chinese National RoboCup Committee. He was Senior Program Committee Member of IJCAI'11, '09, AAAI'11 and AAMAS'12, Co-chair of the 2008 Robot World Cup Competition, etc.
Prof. Chen has been focused on the research and teaching in the field of Artificial Intelligence and Autonomous Robotics. He established and has led the USTC Multi-Agent Systems Lab and robot team, WrightEagle, the first Chinese team that ever entered the international RoboCup competitions, the first Chinese legged robot team, and the first Chinese service robot team that entered the final of RoboCup@home. The teams won 5 champions and 9 runners-up in RoboCup world championships. With these platforms, Prof. Chen found the KeJia Project in 2008, a long-term Cluster of Excellence at USTC which aims at developing a human-level intelligent service robot, in a sense similar to what Alan Turing specified in his "Thinking Machine".
Prof. Chen won the USTC President Award for Research Excellence in 2010.
