Jim VanDerslice, PhD is a Professor and Division Chief of the Division of Public Health in the Department of Family Medicine and Public Health where he holds the TFH Morton Endowed Chair He is a member of the Cancer Control and Population Sciences Program at the Huntsman Cancer Institute, and a Faculty Affiliate in the Population and Pedigree Resource, Utah Population Database. He earned his doctoral and master degrees in Environmental Sciences and Engineering at the School of Public Health, University of North Carolina – Chapel Hill, followed by post-doctoral study at the Carolina Population Center at the same institution.

His research focuses on the development and transmission of antimicrobial resistant organisms in the environment, and exposure ascertainment methods for large retrospective studies using spatial methods. He teaches graduate courses in data collection, data management and analysis and environmental health.

Prior to arriving at the University of Utah he served as the Senior Environmental Epidemiologist at the Washington State Department of Health, and as an Assistant Professor and Program Director with the El Paso Campus MPH program for the University of Texas – Houston, School of Public Health.

Research Statement

James VanDerslice, MSEE, PhD, is an environmental epidemiologist who focuses on methods to assess community exposures and the relationships between these exposures and a wide variety of health outcomes. He is currently working on studies of the impacts of poor ambient air quality on suicide, pneumonia, sperm quality, carcinoid and testicular cancer and pre-term birth. Dr. VanDerslice also has a long-standing interest in the impacts of poor drinking water quality, sanitation and hygiene (WASH) in low-resource settings and the engineering, social and economic systems needed for sustainable improvements in WASH. His current research focuses on the spread of antimicrobial-resistant enteric organisms from human and animals’ wastes to human populations.
