Research Interests:

My research involves the use of animal models to study the behavioral pharmacology of addiction to nicotine and other drugs of abuse. The long-term goal of this work is to inform the development of more effective preventions and treatments for drug addiction. Specific areas of interest include: a) Development of models involving tobacco product exposure to inform FDA regulation of tobacco products and to understand the role of non-nicotine constituents in tobacco addiction; b) Role of negative affective (emotional) withdrawal symptoms and other factors in individual differences in vulnerability to drug addiction; c) Development of novel pharmacotherapies for addiction including the neuropeptide oxytocin and immunotherapy (vaccines and monoclonal antibodies). I use a number of behavioral models to address these areas including intracranial self-stimulation, intravenous drug self-administration, drug discrimination, place / taste conditioning, and locomotor sensitization.
