Drug abuse and mental illness

Drug abuse represents one of the most significant health challenges in the 21st century, with major impacts on individual health and societal support. Closely linked to this problem are the both causative and resultant effects on mental health. Faculty in this group are investigating the cellular and behavioral effects of drugs of abuse, employing genetic through behavioral techniques. The goal of these studies is to improve the treatment of medical disorders through a better understanding of the pharmacology of agents and their mechanisms of action with the purpose of developing safer and more effective pharmacological therapies as well as elucidating the basic mechanisms of drug actions and addiction.
