Brief History I received B.Sc degree in statistics from Peking University in 1990, M.Sc degree from Qufu Normal University in 1993 and Ph. D from Institute of Applied Mathematics, Chinese Academy of Sciences in 1996, both in operational research and optimal control. I have been a postdoctoral fellow at State Key Laboratory of Scientific and Engineering Computing, Hong Kong Polytechnic University, and University of New South Wales. My research had been mainly supported by Australian Research Council (ARC) (2000-2004). In 2004, I was awarded by ARC a Queen Elizabeth II fellowship (QEII fellow). Since September 2004, I moved to University of Southampton to take up a lectureship in Operational Research. Senior lecturer and Associate Professor (2010--2016), Professor and Chair (2017--).

Research Projects

Matlab Codes
• EMBED Package EMBED.zip (EMbedding the Best Euclidean Distances)
• Code based on the LAgrangian Dual approach for source localization problems (paper) (LAD.m). You also need (ENewton.m), (fga.m), and (HANSO2.01)
Give it a test (testLAD.m) by setting example = 'BLTWY06'.
The GTRS matlab code (GTRS.m) used in the paper.
• Computing the nearest EDM matrix to a given pre-distance matrix (ENewton.m)
• Computing the nearest correlation matrix to a given matrix with a simple bound (BcorNewton.rar )
• Computing the nearest correlation matrix to a given symmetric matrix with various constraints (downloadable from Prof. D. Sun's page)
• Best convex interpolation and smoothing over given one-dimensional data (ConvexShape.m)
• Best shape-preserving interpolation over a given set of data (ShapePreserving.m)
