My primary research interest is the application of physics and cognitive science to psychiatry to understand better the origin of psychiatric illness. In collaboration with Charles J. Lumsden (departments of medicine and physics, University of Toronto), I have been working on mathematically modeling mood, drawing on recent developments in non-linear dynamics (Mainzer 1996), fractal geometry (Mandelbrot 1982), and self-organized criticality (Bak 1996;Jensen 1998) to illuminate the mechanism(s) that underpin mood. This approach understands mood as a dynamic process embedded in time; it is uniquely relevant to child and adolescent mood disorders as well as mood disorders across the rest of the lifespan since it approaches mood as a phenomenon.
My other research interests are the application of information technology to clinical psychiatry. I maintain an active interest in data security issues as applied to clinical practice. Ongoing projects (in collaboration with Prof. Lumsden, Dr. Anthony Levitt, and others) include mental health telemetry, the clinical use of handheld computers, and animated mood questionnaires.
