Broadly speaking, my research focuses on individual differences in risk and resilience for adverse mental and physical health outcomes, and potential mechanisms underlying these associations. The individual differences of interest include personality, cognitive (especially executive) functioning, and psychophysiological factors (especially tonic respiratory sinus arrhythmia [RSA]). My program of research focuses on the inter-relations among these individual differences in risk and resilience in the context of stress regulation (i.e., stress exposure, reactivity, recovery, and restoration). Current research is particularly focused on restoration and stress, including 1) phenotypic and endophenotypic characteristics of habitual short sleepers; and 2) individual differences in the experience of aesthetic stimuli (i.e., art, nature, and beauty).
