Research Summary:

Dr. Kreindler’s 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, U of T), he has been working on mathematically modeling mood, drawing on recent developments in nonlinear dynamics (Mainzer 1996), fractal geometry (Mandelbrot 1982), and self-organized criticality (Bak 1996;Jensen 1998) to illuminate the mechanisms 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.

His other research interests are the application of information technology to clinical psychiatry. He maintains 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.
