Principal Investigators

Dr. Chris Richardson

Dr. Chris G. Richardson completed a Bachelors (honours) degree in Biopsychology at the University of Guelph and an MSc in Community Health at the University of Northern British Columbia. He received his PhD from the Department of Health Care and Epidemiology at the University of British Columbia.

Dr. Richardson’s primary program of research is focused on investigating how the use of substances (primarily tobacco, alcohol and marijuana) shifts from experimental to more regular patterns of consumption within the psychosocial context of adolescence. He is particularly interested in quantitative modeling that examines how the process of addiction/dependence develops. For example, using latent growth mixture models to identify distinct patterns of emerging tobacco dependence and parallel process models that examine the influence of emerging psychosocial risk factors in conjunction with patterns of substance use.
