I am a basic researcher in neuroscience and cognition with a focus on neuroendocrine responses to stress, early childhood adversity, life history strategy, and the formation of attachments in early life and adulthood. I study how individual differences in reactivity to stress mediate depression or resilience and alter attachment processes. Current research examines etiological factors in men with violent sexual interests and paraphilias, and the role of behavioral and emotional synchrony in attachment and sexual/romantic health.
