We use sophisticated behavioral tests to probe fundamental features of motivated behavior and decision making in rodents in order to study the systems that support such behavior and determine how these systems may be dysregulated by environmental factors to produce behavioral pathology, such as compulsive drug use and overeating. We are also interested in how developmental changes in these systems give rise to age-related changes in decision making and motivation. Techniques used in the lab include in vivo fast-scan cyclic voltammetry, optogenetics, behavioral pharmacology (systemic and intracranial drug administration), temporary and permanent focal brain lesions, neuroanatomy, as well as a range on behavioral approaches involving food and drug self-administration.
