Research Interests:

My primary objective is to develop new theories (and their corresponding algorithms) for data approximation: Given a set of data (possibly contaminated), construct a function/surface which is close in some sense to the original (unknown) function/image/surface. Specifically, my research interests are as follows: Subdivision Scheme, Wavelet, Scattered Data Approximation by RBF (Radial Basis functions), Image Processing and Numerical PDE.
