I am with the Department of Statistics and Actuarial Science at The University of Hong Kong. Previously I worked for several years as professor in applied mathematics and statistics in the Department of Mathematics, University of Rennes 1, France. My current research mainly focus on high-dimensional statistics and the theory of random matrices, particularly on spectral properties of a large sample covariance matrix and their applications. Application areas include image analysis, bioinformatics and network data analysis.
