Dr. Marshall's research interests focus on substance use epidemiology and the social, environmental, and structural determinants of health of urban populations. In particular, his work seeks to inform public health and policy interventions that improve the health of drug users. He is also interested in applying complex systems methods to examine factors that perpetuate HIV transmission, and to identify interventions that reduce infectious disease spread in drug-using populations.

Biography

Brandon Marshall is an Assistant Professor in the Department of Epidemiology at the Brown University School of Public Health. He received his PhD in epidemiology from the School of Population and Public Health at the University of British Columbia. During his Master's and Doctoral training, he worked as a Research Coordinator at the Urban Health Research Initiative within the British Columbia Centre for Excellence in HIV/AIDS in Vancouver, Canada. In 2011, he completed postdoctoral training in the Department of Epidemiology at the Columbia University Mailman School of Public Health.

Research Description

Dr. Marshall's research focuses on three primary areas of interest: investigating the social, environmental, and structural determinants of health among vulnerable and drug-using populations; substance use epidemiology; and the evaluation of novel approaches and interventions to improve urban health.

His research seeks to identify the multi-level determinants of health inequities (including HIV risks) experienced by drug-using populations. He is involved in a number of large observational cohort studies, including the Vancouver Injection Drug Users Study (VIDUS) and the At Risk Youth Study (ARYS), operated by the Urban Health Research Initiative at the British Columbia Centre for Excellence in HIV/AIDS. The objectives of these studies are to understand the many factors that affect the health of urban drug users and to identify interventions that mitigate the health and social harms associated with substance use.

As an example of this research, in 2011, Dr. Marshall led a study demonstrating a 35% reduction in community overdose mortality following the opening of Insite, North America's first supervised injecting facility. This article was published in The Lancet, and the findings received wide national and international media attention.

More recently, Dr. Marshall has undertaken work that applies complex systems dynamics methods to understand how interacting micro-, meso-, and macro-level factors influence HIV vulnerability in drug-using populations. The objective is this work is to inform more effective HIV prevention and drug policy interventions that reduce health disparities in urban under-served communities. This work was originally funded by a Postdoctoral Fellowship from The Canadian Institutes of Health Research and is now funded by a Developmental Grant (P30AI042853) from the Lifespan/Tufts/Brown Center for AIDS Research. The project is a collaboration between researchers at the Columbia University Mailman School of Public Health and the Community Vulnerability and Responses to Drug-User-Related HIV/AIDS Study at National Development and Research Institutes, Inc.

Dr. Marshall has published more than 50 scientific publications, including articles in JAMA, BMJ, and The Lancet. He has won numerous awards for his work, including the Canadian Association for HIV Research New Investigator Award (epidemiology) in 2008 and the American College of Epidemiology student prize in 2010. His work has been featured in Science, Psychiatric News, Scientific American, The Globe and Mail, and CTV News.
