A cross-divisional department spanning

Research and Practice

Faculty Research Interests

The Department of Environmental Health and Engineering has a diverse range of research areas, which focus on the adverse influence of the environment on human health and with controlling these influences. In this regard, the Department considers “environment” in its broadest sense, including the natural, built and social environments.

Our faculty's research focuses on agents in the environment, including biological, chemical and physical environmental agents. The Department engages in a number of activities within this traditional approach, including studies of the sources and environmental distribution of such agents; human exposure to such agents; the body’s response at the molecular, cellular, organ system- and whole-body levels; environmental risk assessment; and prevention and intervention strategies (including environmental engineering, law, policy and communications solutions).

Faculty MemberResearch Focus
Joseph Bressler
Associate Professor
Dr. Bressler's laboratory has been studying transporters and their interaction with environmental toxins.
One Health Laboratory at Johns Hopkins University
Meghan Frost Davis
Associate Professor
The One Health Laboratory at Johns Hopkins University examines the interface of bacteria and hosts to reduce microbe-mediated disease in humans and animals. 
DeCarlo Lab at Johns Hopkins
Peter DeCarlo
Associate Professor
The DeCarlo Lab is focused on the measurement of chemicals in the air we breathe and how that information can be used to advance science and inform policy.
Harman Research Group (Landscape Hydrology@JHU)
Ciaran Harman
Assistant Professor
Dr. Harman's research group studies water flow and transport. Their work combines field work, experimental studies, and numerical modeling.
The Johns Hopkins Environmental Health Microbiology and Immunology Laboratory
Christopher D. Heaney
Associate Professor
Dr. Heaney's research focuses on improving understanding of the dynamics and determinants of environmental and occupational stressors and infectious diseases.
Koehler Research Group
Kirsten Koehler
Professor
Dr. Koehler's goals are to improve exposure assessment methods to inform occupational and public health policy. Her research goals involve the use of direct-reading instrumentation to improve spatiotemporal exposure assessment.
Kohr Laboratory of Cardiovascular Redox Signaling
Mark Kohr
Associate Professor
The focus of the Kohr Laboratory of Cardiovascular Redox Signaling is to elucidate redox-sensitive signaling pathways and to define the mechanistic consequences of redox-based post-translational protein modifications in healthy and diseased myocardium, namely S-nitrosylation and other forms of oxidation.
Greenhouse Gas Research Group
Scot Miller
Assistant Professor 
The Greenhouse Gas Lab studies the emissions of greenhouse gases and air pollutants.
Nachman Research Group
Keeve Nachman
Professor
Program Director, Food Production & Public Health Program
Center for A Livable Future
Dr. Nachman's research interests include arsenic, food systems, risk science, risk assessment, environmental epidemiology, industrial food animal production, animal waste, animal feed, foraging, urban gardens, agriculture, biosolids, veterinary drugs, Chesapeake Bay watershed protection, antimicrobial resistance, exposure assessment, regulatory toxicology, regulatory policy, chemical residues in food.
Preheim Lab Group
Sarah Preheim
Assistant Professor
The Preheim Lab Group seeks to understand, predict and manipulate complex microbial community function with a goal towards protecting and sustaining human and environmental health.
Research Program of Dr. Ramachandran
Gurumurthy RamachandranProfessor
Dr. Ramachandran has conducted research in various areas relating to human exposure assessment in occupational, residential, and outdoor settings.
Ruggero Rossi
Assistant Professor
The Ruggero Rossi Group works at the intersection of electrochemistry, microbiology, and engineering to achieve a sustainable energy-water infrastructure, and environmentally sustainable production of chemicals.
Shilva Shrestha
Assistant Professor
The Shrestha Lab focuses on developing sustainable resource recovery biotechnologies to produce bioenergy and biochemicals from waste biomass.
