Eric Brown is a psychiatrist, teacher and researcher working at the Centre for Addiction and Mental Health in geriatric psychiatry. He completed his medical degree at McMaster University and his psychiatric residency at the University of Toronto. He subsequently completed a graduate degree with the Institute of Medical Science and a fellowship in geriatric psychiatry. His research training and interests include using neuroimaging (positron emission tomography and magnetic resonance imaging) to explore the pathophysiology of psychiatric symptoms and disorders including depression and cognitive impairment. He is exploring the potential role of environmental exposures on the development of dementia. He is also interested in open source data, statistical analysis and reproducibility in psychiatric research and is the author and maintainer of open source R packages supporting psychiatric research. Clinically, he works primarily on a geriatric inpatient psychiatry unit at the Centre for Addiction and Mental Health and supervises clinical trainees.

Research Synopsis

Dr. Brown’s research interests include exploring the pathophysiology of cognitive decline using multimodal neuroimaging approaches including positron emission tomography. He is interested in maximizing the clinical and research utility of available technologies, and in open and reproducible analytic approaches. He is exploring the potential contribution of environmental exposures to the pathophysiology of cognitive impairment. He uses meta-analytic techniques to quantitatively summarize the literature.
