RESEARCH/TEACHING INTERESTS

1.  Neurobiology/neurocircuitry of substance/alcohol use disorders
2.  Neuropeptide contributions to compulsive drug/alcohol intake
3.  Sleep dysfunction comorbidity in substance/alcohol use disorders

Research interests in our laboratory center around the neurobiology and neurocircuitry underyling addiction and related comorbidities. Our studies primarily focus on the role of negative reinforcement in the motivation to excessively seek and take drugs of abuse (including psychostimulants and opioids) and/or alcohol. We largely use an extended access to drug/alcohol self-administration paradigm as an animal model of drug and alcohol addiction that mimics the transition from recreational use to excessive, compulsive use associated with dependence in humans. In conjunction with other multidisciplinary techniques, this dependence model allows us to examine the neurobiological mechanisms that underlie compulsive behavior patterns of addiction and sleep alterations associated with dependence and withdrawal. Our addiction research focuses on the contributions of stress system sensitization, reward deficits, and sleep dysfunction to various states of dependence, including withdrawal and relapse. Current neurotransmitter/peptides of interest include hypocretin/orexin, dynorphin, and norepinephrine. Our ultimate goal is to identify potential neurobiological targets for the pharmacological treatment of substance use disorders that can be used in combination with behavioral therapies in the clinical setting.
