Biography

I'm an Assistant Professor at the Department of Computer Science at City University of Hong Kong. I worked as a Postdoctoral Research Associate at University of New South Wales (UNSW) 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 both from the School of Information Science and Engineering, Shandong University (SDU) , China, in 2010 and 2013, respectively.

[Recruitment] I'm leading the S2MC lab@CityU and we're looking for self-motivated PhD students to join us. I have relatively broad research interests, but generally my previous research focuses on IoT such as smart sensing, IoT security, IoT+AI, wireless network etc (please visit our group website for more details). For current available PhD positions in my group. please visit Recruitment for more information.
