Dr. Xiaochun Cao is the Dean of School of Cyber Science and Technology, Sun Yat-sen University. His research interests include: artificial intelligence especially computer vision, and content analysis in cyber space, etc. He received the B.E. and M.E. degrees both in computer science from Beihang University (BUAA), China, and the Ph.D. degree in computer science from the University of Central Florida, USA, with his dissertation nominated for the university level Outstanding Dissertation Award. After graduation, he spent about three years at ObjectVideo Inc. as a Research Scientist. Before joining SYSU, he was a professor at Institute of Information Engineering, Chinese Academy of Sciences. He has authored and coauthored over 300 journal and conference papers. In 2004 and 2010, he was the recipients of the Piero Zamperoni best student paper award at the International Conference on Pattern Recognition.
Dr. Cao was the recipients of Outstanding Young Scientists Fund and Excellent Young Scientists Fund of National Natural Science Foundation of China, in 2020 and 2014, respectively. He is on the editorial boards of IEEE Transactions on Pattern Analysis and Machine Intelligence, IEEE Transactions on Image Processing, IEEE Transactions on Multimedia, and Acta Electronica Sinica. He was on the editorial board of IEEE Transactions on Circuits and Systems for Video Technology. 
Four of Prof. Cao's former Ph.D. students, Xiaojie Guo(2013), Changqing Zhang(2016), Xiao wang(2016), and Wenqi Ren(2017), were the recipients of Excellent Young Scientists Fund of National Natural Science Foundation of China or National High-level personnel of special support program. Three of his former Ph.D. students, Wenqi Ren(2017), Ke Ma(2019), Pengwen Dai(2022), were the winners of China Computer Federation (CCF)/Chinese Institute of Electronics(CIE)/Chinese Academy of Sciences(CAS)/  Doctoral Dissertation Awards.
