RESEARCH INTERESTS

The mission of the joint NIAAA-NIDA Section on Clinical Psychoneuroendocrinology and Neuropsychopharmacology (CPN) is to contribute to a deeper understanding of possible pharmacological treatments for alcohol and drug use disorders. We conduct outpatient and inpatient clinical studies using a combination of state-of-the-art and novel biobehavioral and pharmacological procedures performed under well-controlled human laboratory conditions, in order to identify possible novel medications for addiction. This section is particularly interested in: 1) investigating  feeding-related pathways (e.g. ghrelin, GLP-1, insulin, hypothalamus-pituitary-thyroid axis, oxytocin) as novel neuropharmacological targets for alcoholism; and 2) identifying biobehavioral mechanisms and markers that predict treatment outcomes of promising medications (e.g. GABAB agonists) for the treatment of alcoholism.
