Hongwei Liang's Homepage

Short Bio

Hongwei Liang received his Ph.D. in Computing Science at Simon Fraser University in May 2018. He was working at the Database & Data Mining Lab, advised by Prof. Ke Wang, during his Ph.D studies. Before that, he got the Bachelor's degree in Software Engineering from Harbin Institute of Technology, China in July 2012.

His research interests broadly span data mining and machine learning, and he was focusing on the topics of social network behavioral data mining, spatio-temporal recommendation and search during his Ph.D studies.
