 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 

Molecular Biophysics and Cellular Mechanics Lab of Dr. Steven An

Steven An, PhD
Associate Professor

 

Dr. An's current work comprises both basic and translational research focusing on the cellular and molecular basis for obstructive lung diseases and exploring new intervention strategies.

Daniel Barnett, MD
Associate Professor

Dr. Barnett's research includes best practice models to enhance all-hazards public health emergency readiness and response.

Shyam Biswal, PhD
Professor

Dr. Biswal's research focuses on understanding the host factor, Nrf2 that regulates stress response transcriptional program and protects against a range of pathological process (oxidative stress, inflammation, and apoptosis) in diseases such as COPD, lung cancer, and sepsis and develop a novel approach for intervention of these inflammatory diseases by targeting this host factor.

Bouwer Research Group
Ed Bouwer, PhD
Professor

Dr. Bouwer’s research interests encompass factors that influence biotransformation of contaminants; bioremediation for control of contaminated soils and groundwaters; biofilm kinetics; biological processes design in wastewater, industrial, and drinking water treatment; and transport and fate of microorganisms in porous media.

Joseph Bressler, PhD
Associate Professor

Dr. Bressler's laboratory has been studying transporters and their interaction with environmental toxins.

Chen Research Group
Kai Loon Chen, PhD
Assistant Professor

 

Dr. Chen's lab research focuses on the environmental and health implications of nanotechnology and the application of nanotechnology for water treatment, membrane processes, and environmental remediation.

The Environmental Microbiology Laboratory of Dr. Meghan F. Davis
Meghan Frost Davis, PhD, DVM
Assistant Professor

 

Dr. Davis' research examines the interface of bacteria and hosts to reduce microbe-mediated disease in humans and animals. Her research applies the principles of one health and microbial ecology, evaluating target microbes and bacterial genes specifically and the larger microbial community (microbiome) broadly.

John D. Groopman, PhD 
Anna M. Baetjer Professor

Dr. Groopman’s research involves the development, validation and application of molecular biomarkers of exposure, dose, and effect from environmental carcinogens to high-risk populations. A major emphasis of the research has been in the elucidation of the role of aflatoxins, a common contaminate of the food supply, in the induction of liver cancer in high-risk populations living in Asia and Africa.

Harman Research Group (Landscape Hydrology@JHU)
Ciaran Harman, PhD
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, PhD
Assistant Professor

Dr. Heaney's research in the Johns Hopkins Environmental Health Microbiology and Immunology Laboratory (JH-EHMIL) focuses on improving understanding of the dynamics and determinants of environmental and occupational stressors and infectious diseases.

Kirsten Koehler, PhD
Assistant 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, PhD
Assistant 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.

Wayne Mitzner, PhD
Professor

Dr. Mitzner's lab emphasizes understanding the physiologic basis of lung health and disease.

Keeve Nachman, PhD, MHS
Assistant 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.

Roni A. Neff, PhD, MS
Assistant Professor
Director, Food System Sustainability Program & Director of Research, Center for A Livable Future

Dr. Neff's research interests in the Food system, food waste, Farm Bill, climate change, agriculture, policy, communication, sustainability, health disparities, Baltimore, history, occupational injury and illness, resilience.

Preheim Lab Group
Sarah Preheim, PhD
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.

Kellogg Schwab, PhD
Professor

Dr. Schwab’s research focuses on environmental microbiology and engineering with an emphasis on the fate and transport of pathogenic microorganisms in water, food and the environment. This work includes extensive laboratory-based research designed to develop and evaluate molecular detection methods with subsequent application of these methods in field-based investigations.

Brian S. Schwartz, MD
Professor

Dr. Schwartz's research focuses on the health effects of chemicals on the central nervous system, land use, built environment, the influence of "sprawl" on public health, the public health implications of climate change; the coming era of energy scarcity; sustainability challenges. 

Winnie Tang Epigenetics Laboratory
Winnie Tang, PhD
Assistant Professor

Dr. Tang's current research focuses on deciphering how environmental pollutants/allergen and dietary factors alter the epigenome via DNA de/methylation and induce chromatin remodeling, leading to cancer or other common diseases like asthma and cardiovascular disease.

The Wang Laboratory of Human Environmental Epigenomes
Zhibin Wang, PhD
Assistant Professor

The long-term goal of the Wang laboratory is to determine how epigenetic codes, including patterns of DNA methylation and combinatorial patterns of simultaneously occuring histone modifications, are established and how this establishment goes awry upon environmental stimuli, thus contributing to human diseases (such as cancers and autoimmune diseases).
