Biography
I'm a tenured Associate Professor at the Department of Computer Science at City University of Hong Kong. Before that, I worked as a Postdoctoral Research Associate at the School of Computer Science and Engineering (CSE) at UNSW Australia from June 2017 to August 2019. I obtained my PhD degree from the University of Queensland in 2017 (advised by Prof. Neil Bergmann and Prof. Wen Hu). I received my B.E. degree in Communication Engineering and M.E. degree in Communication and Information System (advised by Prof. Dongfeng Yuan) both from the School of Information Science and Engineering, Shandong University (SDU) , China, in 2010 and 2013, respectively.
