His research interests have spanned both personality dynamics as well as health psychology. He has conducted studies of object relations and defense mechanisms development, changes in these constructs in response to psychological treatments, and the relationship between psychodynamic personality constructs and psychopathology. As a health psychologist, he has conducted studies of collaborative care (i.e., physicians working side-by-side psychologists in medical settings), predictors of difficult physician-patient relationships, accuracy of self-ratings of physicians during objective structured clinical exams, and has developed curricula for collaborative care in residency programs.
