Dr. Ruiyuan Li is an associate professor with the College of Computer Science, Chongqing University, China. He was the Head of Spatio-Temporal Data Group in JD Intelligent Cities Research, leading the research and development of JUST (JD Urban Spatio-Temporal data engine). Before joining JD, he had interned in Microsoft Research Asia from 2014 to 2017. He received the B.E. and M.S. degrees from Wuhan University, China in 2013 and 2016, respectively, and the Ph.D. degree from Xidian University, China in 2020, under the supervisor of IEEE Fellow and ACM Distinguished Scientist Professor Yu Zheng. His research focuses on Spatio-temporal Data Management and Mining, Distributed Computing, and Urban Computing. He has published over 30 refereed papers, and applied for over 30 Chinese patents. One of his patents got the China Patent Excellence Award. He received the Excellent Doctoral Dissertation Award of Shaanxi Computer Society in 2020. He is a member of CCF (China Computer Federation), a member of IEEE and ACM, a member of Technical Committee on Databases of CCF (the first member in Chongqing City), and a member of Technical Committee on Pervasive Computing of CCF. He is a reviewer of several top-level conferences and journals. JUST system, which he was responsible for, has been successfully deployed in many national projects of China.
The biggest advantage of Dr. Ruiyuan Li is that he not only has a research background in several top universities, but also has experience in several big enterprises. Whether you are interested in academic research or are preparing to work in industry, you can feel free to contact him.
