My path to psychology might be considered nontraditional: I began in music school studying the classical guitar at the Peabody Conservatory (Baltimore, MD) completing a bachelor's degree in music performance at the University of South Carolina (Columbia, SC) and continuing there as Director of the Classical Guitar Program. I went on to complete my master's and doctoral degrees in clincal psychology at the University of Wisconsin-Milwauke. I spent my formative years in several European countries and I continued to travel, live, work and study in countries that include Japan, Korea, Germany, Italy and Sweden (I am a strong believer in the value of an international perspective and diversity).
I generally teach courses and conduct research in the areas of psychopathology, personality, and related topics such as psychological testing and measurement.

I am interested broadly in understanding differences between people in personality traits and psychopathology, the origins of these differences, and their effects on important life outcomes. I am also interested in late-life psychological functioning and aging generally, and, in particular, the nature and impact of affect, primarily depression. I have been fortunate to conduct research in aging using data from ongoing twin studies in Denmark; I particularly enjoy international and interdisciplinary collaborations.
"Often before now I have applied my thoughts to the puzzling question – one, probably, which will puzzle me for ever – why it is that, while all Greece lies under the same sky and all Greeks are educated alike, it has befallen us to have characters so variously constituted." Theophrastus
