    Research Interests

    Animal models of disease remain crucial as a tool in science, helping us understand the mechanisms behind various human diseases by attempting to imitate to the best of our ability the pathologies of interest. In psychology (and relatedsciences), such models of disease are utilized to investigate the physiological mechanisms involved in psychiatric disorders. It is our goal to utilize such behavioral modeling of psychiatric disorders such as depression, schizophrenia, Parkinson’s disease and drug abuse to investigate the neurobiological mechanisms that contribute to dysfunctional behavior.
