For the past 15 years, I have been conducting research relating to the reliability, validity, and clinical accuracy of neurocognitive assessment. I am the lead investigator in a multi-year, programmatic research effort relating to developing and evaluating new evidence-based psychometric criteria for mild cognitive impairment in psychiatry and neurology.

The research area that I’m most passionate about is outcome from mild traumatic brain injuries. I am pursuing this research from a broad-based biopsychosocial perspective. I am part of a network of research collaborators from across Canada and the United States. Some of our research relating to sport-related concussion is presented below.

I am deeply committed to studying outcome from MTBI in civilians and military personnel. I’m interested in the complexities of good and poor outcome in injured adolescents and adults. Our latest thinking and research in this area is interdisciplinary (e.g., neuroscience, neuropsychology, clinical psychology, social psychology, neurology, biological psychiatry, and clinical psychiatry). Internationally, I am a leading researcher in the area of mild TBI and mental health (e.g., depression and anxiety disorders). Understanding poor outcome from MTBI requires, in my view, a biopsychosocial perspective.
