Biography

John R. Best, PhD completed his PhD at the University of Georgia, and has since completed postdoctoral fellowships at Washington University School of Medicine in St. Louis and the University of British Columbia. Most recently, Dr. Best was a Research Associate at the University of British Columbia in the Aging, Mobility, and Cognitive Neuroscience Laboratory. Dr. Best’s research interests fall within the emerging, interdisciplinary field of health neuroscience, which aims to understand how the brain both affects and is affected by physical health. The aim of this work is to (1) gain a better understanding the modifiable risk factors for cognitive impairment and dementia, (2) identify the role of neurocognition, both independently and in interaction with environmental and social factors and incentives, in determining adherence to positive health behaviours, and (3) design lifestyle interventions that reduce dementia risk and manage its progression. This work has been supported by fellowships from the US National Institutes of Health, the Michael Smith Foundation for Health Research, and the Canadian Institutes of Health Research.
