I received the B.S. and M.S. degrees in computer science from Central South University, Changsha, China, and the Ph.D. degree in computer science from the University of Victoria, Victoria, BC, Canada. From 2013 to 2017, I was a Research Engineer with the Central Research Institute, Huawei Technologies Company Ltd., Shenzhen, China. Since 2017, I have been an Assistant Professor with the School of Automation, Guangdong University of Technology, Guangzhou, China. I have published more than 30 journal and conference papers in peer-to-peer systems, VANETs, DTNs, and mobile computing systems. My research interests include edge computing, VANETs, satelite networks and cyber-physical systems.

I am actively recruiting self-motivated undergraduate/graduate students with sufficient research funds.  Interested students can contact me through email (lechang@gdut.edu.cn).
