As an evolutionary social & personality psychologist, my research applies adaptationist principles to the study of human nature. To this end, my (typically collaborative) research applies theory and methods from multiple disciplines, including social-personality psychology, evolutionary biology, behavioral ecology, cross-cultural psychology, computational modeling, behavioral endocrinology, and molecular genetics.

Research Areas

The research topics in my research lab are diverse, but united by the goal of applying formal and computational models from behavioral biology to the study of human psychology, behavior, and health. For example, recent modeling work suggests that an organism’s overall orientation toward investing in future reproduction (vs. a present-focus) should be calibrated in response to internal (somatic) and external (socioecological) cues to mortality risk, such that individuals who compute their mortality risk as being low adopt a more future-oriented strategy. Recent correlational studies from my lab provide evidence consistent with these predictions: environmental harshness in childhood predicts a range of intercorrelated behavioral indicators of present-future orientation, and this association is partly mediated via overall physical health. A similar study that is currently under review for publication tests whether earlier sexual maturation (among women) and shorted telomeres on chromosomes (among males) may additionally mediate the association between childhood environment and adult behavioral strategies. Given the difficulty of empirically assessing an individual’s overall intrinsic mortality, we are currently investigating whether mortality risk ratings assigned to individuals by life insurance companies predict the present-future orientation spectrum.

Other ongoing projects pertain to the role of endocrine responses in regulating men’s courtship behavior, cross-cultural studies of social status and partner preferences, adaptationist models of emotions, and the construction of a new meta-theoretical framework for personality science.
