Biography

Dr. Katzman is the Clinic Director and Staff Psychiatrist at the S.T.A.R.T. Clinic (Stress, Trauma, Anxiety, Rehabilitation and Treatment) for Mood and Anxiety Disorders. He is also a faculty member at the Northern Ontario School of Medicine (Laurentian University and Lakehead University) as well as in the Department of Psychiatry at the University of Toronto. He is also appointed in the Department of Psychology at Lakehead University and is a member of the Faculty of Psychology at Adler School of Professional Studies. Dr. Katzman was trained at the University of Toronto, first undertaking his B.Sc. in
Psychology and Neuroscience, and subsequently his medical training and residency.
Dr. Katzman’s clinical work deals chiefly with the diagnosis and treatment of adults suffering with mood and anxiety disorders, as well as those suffering with chronic Attention Deficit Disorders, Executive Dysfunction as well as chronic pain, providing expert diagnostic assessment, and pharmacological treatment as well as Cognitive Behavioural Therapy in both group and individual formats, psychodynamic treatment and Mindfulness Based treatments.
As an educator, Dr. Katzman has developed numerous training programs for both students and clinicians including medical students and residents, primary care physicians, psychiatrists, psychologists, social workers, occupational therapists, nurses, a variety of support workers as well as naturopaths, and other complementary and alternative medicine clinicians. His research primarily involves examining the psychological manifestations associated with executive dysfunction in the mood, anxiety and traumatic disorders. Most recently, his specific recent interest has involved examining the role of “Intolerance of Uncertainty” as a driver of psychopathology and the role of hedonic tone in predicting the presence of comorbid conditions and differential response to treatment. In the past he has used such varied tools as positron emission tomography, the respiratory physiological challenge, and Doppler imaging, in association with a variety of anxiogenic challenges.
Dr. Katzman is also a founding member of the Board of Directors as well as the founding and current Chair of the Scientific Advisory Board of the Anxiety Disorders Association of Canada/Association Canadienne des Troubles Anxieux (ADAC/ACTA).
He is the chair of a variety of scientific advisory boards, on the editorial board for a number of journals, and has published numerous papers in the areas of Anxiety, Mood, Pain and Attention Disorders.

The focus of his research has been related to Hypoprefrontality, Executive Dysfunction, Intolerance of Uncertainty and Low Hedonic Tone in relation to the development of a variety of comorbidities in association with treatment resistance.
