Zhi Cai (A.Prof./Ph.D.)

 

Bio

I am an Associate Professor in Big Data and Artificial Intelligent Group, College of Computer Science, Faculty of Information Technology, Beijing University of Technology.

I worked as a Post-doc at Department of Computing and Math, Manchester Metropolitan University, from where I also received my Ph.D. in Computer Science in 2011 (supervisor Prof. Georgios Fakas). I also did a short visit at the Department of Computer Science, The University of Hong Kong 2014 (supervisor  Prof. Nikos Mamoulis). I studied M.Sc. Degree of Computer Science from Health and Bio-informatics Group, School of Computer Science, The University of Manchester in 2007 and B.Sc. of Computer Science from Computer and Communication Engineering School, Tianjin University of Technology in 2006.
