Research interests

• Cannabinoids, opioids, and drugs of abuse
• Endocannabinoid system in reward/stress
• Stress resilience and comorbid factors to drug taking

My laboratory focuses on long-term models of excessive drug taking, to provide a more holistic basis for studying potential therapeutic targets and consequences of drug addiction.  Work in the laboratory revolve around extended-access drug self-administration paradigms, as well as tracking and tracing of behavioral and physiological markers during the transition from stable to excessive drug seeking and intake.  Among the aspects of interest includes pain sensitivity, anxiety, depressive-like states, and markers of stress.

Studies also include potential factors that may impact relapse, recovery, and response to drug re-exposure.  Measures of intracranial self-stimulation (ICSS) in response to drug intake, both passive and active, as well as during withdrawal and abstinence, provide insight into mood and reward states throughout the various stages of drug use.

Current treatment targets of interest include the kappa opioid receptor/dynorphin system, the endocannabinoid system, and drug of abuse vaccines.
