My longstanding research aims are to explore the causes and consequences of functional versus dysfunctional relationship communication, including social support and intimate partner violence (IPV), respectively. Regarding the former, my present focus is on how genetic, neuroendocrinological, and early environmental factors interface with social support exchanged between intimate partners. With respect to the latter, my foci are on (a) the interplay of IPV and problematic substance and alcohol use, (b) examining ways to improve the self-report validity of IPV measures, and (c) factors that influence attitudes towards IPV. I am also beginning a line of research examining the role of situational and dispositional factors that influence men's perceptions of sexual consent.
