Personal profile
Biography
I am a faculty member of the School of Mathematics and Physics and the Centre for Operational Research and Logistics in the University of Portsmouth. I received BSc degree in Mathematics from Peking University in 1999, MA degree in Mathematics and Financial Engineering from York University in 2003, and PhD degree in Systems Engineering and Engineering Management from The Chinese University of Hong Kong in 2011. I have been a faculty member at Ningbo Institute of Technology and Shanghai University. My research is at the interface of Operations Research and Mathematics. In particular, I work on theoretical and computational optimization, algorithm design and analysis, and tensor computation and multilinear algebra.
