Biography

I'm currently an assistant professor at the School of Software Engineering, Sun Yat-Sen University. I received my Ph.D degree at the Faculty of Information Technology, Monash University, Australia, under the supervision of Prof.John Grundy, Dr.Xin Xia and Dr.Jiangshan Yu. Prior to joining Monash University, I spent two years at the Hong Kong Polytechnic University as a research assistant advised by Dr. Daniel Xiapu Luo. My research interests include blockchain, smart contracts, mining software repository, software security, and empirical study.

Looking for highly motivated students in the areas of Blockchain/Smart Contract, Software Engineering. Please contact me if you have interests.
