Before joining the psychology faculty at the University of Northern Iowa,  I was at the University of Missouri (Ph.D., 2001).  My principal area of research involves investigating the influence of estrogen on both normal behavior and the expression of psychopathology, particularly borderline personality. I am broadly interested in how brain function affects behavior, and have done research involving various brain imaging techniques, including ERP’s, optical imaging and MRI.  Current research projects involve direct measurement of estrogen and testosterone levels via radioimmunoassay.  Secondary areas of interest include mathematical development and mathematical disabilities, sex differences in jealousy, and autism.
