Clinical Interests

Dr. Maddock is a psychiatrist with special expertise in Anxiety Disorders, Psychopharmacology and Cognitive Behavioral Therapy.

Research/Academic Interests

Dr. Maddock's research focuses on understanding the brain bases of psychiatric disorders, primarily through the use of MRI and MR Spectroscopy techniques to investigate brain metabolism and function.

He studies a range of disorders, including anxiety, psychotic and mood disorders. He also studies how health-promoting activities such as exercise, sleep, and meditation affect the brain in healthy individuals.
