One area of my research considers
the development of computationally practical robust multivariate location and
dispersion estimators, robust multiple linear regression estimators and resistant
dimension reduction estimators along with the corresponding theory. Another
area of research involves extending least squares theory and creating graphical
diagnostics for generalized linear models and single index models.
