Clinical neurobiology of stress and relaxation, emotion dysregulation, and their effects on desire and drug craving and addictive behaviors, such as, drinking, eating and drug use. Mechanisms underlying sex differences in stress neurobiology, and interaction with motivational processes and effects on health outcomes is integral to this research area. The neurobiology of relaxation and its effect on resilience and chronic stress and emotion dysregulation is also being studied. An additional interest is in developing treatments to target stress related relapse in addictive behaviors. We’ve developed and validated a laboratory model of stress-induced and hedonic cue-induced craving and lapse to addictive behaviors. The laboratory model characterizes the drug craving state and is being applied to test new pharmacological and psychological interventions to reduce craving and drug use behaviors. Individual difference variables such as gender, genetics, early trauma, chronic stress, prefrontal cognitive functioning that may modulate responses to stress and urges are also being studied.
