人员

Dr Zhang obtained his PhD degree in Statistics from the London School of Economics. Before joining EdUHK, he was a Research Assistant Professor in the Department of Applied Mathematics at the Hong Kong Polytechnic University and a Researcher in the Bocconi Institute for Data Science and Analytics at Bocconi University. Dr Zhang's research interests include Bayesian nonparametrics and Bayesian machine learning. He is also interested in applied probability and financial mathematics problems.
