Dr. Clarke's areas of interest include depression treatment/prevention, child and adolescent mental health and treatments, and treatment of substance abuse comorbid with mental disorders. Dr. Clarke has been the principal investigator and co-investigator of several grants funded by the National Institute of Mental Health, conducting controlled outcomes trials of depression treatment and prevention in at-risk populations.

Some of his most recent controlled trials examine the costs and clinical outcomes of preventing and treating depression in adolescent offspring of depressed parents enrolled in an HMO; the medication and psychotherapy treatment of depression in adolescents who have failed to respond to an initial course of SSRI anti-depressant medication; treatment of depression in adults also receiving outpatient treatment for alcohol addiction; simultaneous psychotherapy and medication for depressed adolescents treated in primary care; and Internet self-care programs for depressed adults and adolescents.

Dr. Clarke has been conducting mental health research for 20 years. He received his Ph.D. in Clinical Psychology from the University of Oregon in 1985.
