I received my PhD degree from Shandong University in 2015. My advisor is Professor Ma Jun. Before joining SDU, I obtained my MS degree from Shandong Normal University in 2011 (Supervised by Fangai Liu). I am a Director of the Shandong Artificial Intelligence Society and a member of the Social Media Processing Committee of the Chinese Information Society. I worked as a Visiting Scholar at The University of Queensland (UQ) from 2018 to 2019 (Supervised by Professor Hongzhi Yin). My research grants include the National Natural Science Foundation of China and the China Postdoctoral Science Foundation. Currently, I am working as a Professor and PhD Supervisor at Shandong Normal University, China.
My interesting areas include
