Dr. Cohen conducts research on drinking water (contamination, treatment, and supply) and environmental health in low-income rural communities, with a focus on developing safe water programs. He has over ten years of international experience and has worked for multiple United Nations agencies on projects developing and evaluating water- and poverty-related indicators, including the 2008-2014 design and management of a project to construct the Multidimensional Poverty Assessment Tool. Cohen received his PhD in Environmental Science, Policy & Management, and an MPH in Epidemiology, from the University of California, Berkeley, as well as an MSc in Water Science, Policy, & Management from the University of Oxford. He has taught courses on randomized controlled trials and water & development.
Prior to coming to Virginia Tech, Dr. Cohen worked at UC Berkeley as a Project Scientist and Research Director for The Berkeley/China-CDC Program for Water & Health, a program he helped create and has now expanded to Virginia Tech. Currently, Dr. Cohen is an Assistant Professor of Environmental Epidemiology in the Department of Population Health Sciences at Virginia Tech.
