Dr. Keeley’s primary research interest involves the classification of psychopathology, especially concerning mental health professionals’ use of the diagnostic system. He has studied cognitive processes involved in clinicians’ work, including diagnosis, case conceptualization, and treatment planning. Currently, he is consulting for the World Health Organization on the field trials for the Mental and Behavioural Disorders chapter of the International Classification of Diseases (ICD) as they work towards the eleventh revision. A second interest is the scholarship of teaching and learning, particularly investigating the qualities and behaviors of excellent teachers that lead to superior learning.
