Christopher D. Heaney, PhD
Assistant Professor
Department of Environmental Health and Engineering

Heaney earned his MS in environmental health microbiology and virology and his PhD in epidemiology at the University of North Carolina Gillings School of Global Public Health in 2008. His dissertation, “Contact with Beach Sand and Risk of Illness,” examined the relationship between beach sand contact, densities of fecal microbial pollution in sand, and the risk of enteric and non-enteric illnesses.

His research focuses on environmentally-mediated impacts on health and well-being, specifically community land use, waste disposal, and food production practices, and integrates the academic disciplines of environmental microbiology, molecular biology, immunology, epidemiology, and community-based participatory research (CBPR).

Chris is the director of the Johns Hopkins Environmental Health Microbiology and Immunology Laboratory (EHMIL).
