Brief Introduction
After graduated with his B.Sc. and M.Phil. degree from the Chinese University of Hong Kong (Mathematics Department), he pursued his Ph.D. degree in the University of Wisconsin-Madison (again Mathematics Department) and then joined the University of Hong Kong (still Mathematics Department) in 1991. His current research interests are control and optimal control theory with applications to system stabilities and optimal portfolio selections. As he gets older, he is more and more interested in mathematics related to life especially those from ancient china.
