Dr. LIU’s research interests center around network science, artificial intelligence and their applications in social and economic settings such as social network analysis, diffusion of innovation, online public opinion and cryptocurrencies, etc.

I come from an interdisciplinary background: a Bachelor of Science degree in Internet and multimedia technologies and a Ph.D. degree in network science, both from the Hong Kong Polytechnic University. Before joining CityU, I was an associate professor at the School of Computer Science and Engineering, Southeast University, China.

I am currently affiliated with Prof. Jonathan Zhu's Web Mining Laboratory and Prof. Ron Chen's Centre for Complexity and Complex Networks. I'm also involved in an InnoHK R&D initiative, the Laboratory for AI-Powered Financial Technologies.

My research group studies human behaviors in web3 and the dark web with computational social science methods. Post-doc and data scientist/engineer positions (with an opportunity of pursuing doctoral degree) are available.
