Dr. Farmer's research and clinical interests have been primarily centered on persons who display impulsive or disinhibited tendencies or who express difficulties in self-regulation. In experimental research, he has evaluated various theoretical models of impulsivity and reward sensitivity with diverse clinical groups, including inmates and those with eating disorders and personality disorders. Since 1990, Dr. Farmer's research has also emphasized substance use disorders, diagnostic comorbidity, and personality and clinical assessment.
