Research Interest

My recent interest is on the development of techniques for analyzing high dimensional regression data. The scheme of my approach differs from others substantially on both the technical and the philosophical levels. Inspired by the success of SIR (sliced inverse regression) and PHD (principal Hessian directions), the current effort is to extend these basic tools to more complicated settings while maintaining the basic strategy of reducing the dimension of regressors effectively without imposing model assumptions. This approach takes good advantage of modern computing and graphical facilities.
