Yunbin Zhao received his PhD in Operations Research in 1998 from the Chinese Academy of Sciences. Before joining the University of Birmingham in 2007, he had worked at the Academy of Mathematics and System Science (AMSS), Chinese Academy of Sciences, Beijing, the SEEM of Chinese University of Hong Kong and the Management Department of University of Toronto (Canada). His interest covers computational optimization, operations research and numerical analysis. Recently, he is working on theory and algorithms for the sparsest solution of linear systems and their applications to compressed sensing, sparse signal and imaging processing.
