Research in the Gangarosa Department of Environmental Health spans across a wide range of environmental issues, from the molecular to the global. The breadth of research in the department reflects the diversity of backgrounds and interests of our faculty, students and alumni. We tackle complex environmental health concerns from multiple angles with a variety of methods. Our department has particular strengths in air pollution, toxicology, chemical exposures, climate change, and water, sanitation and hygiene (WASH).

We pride ourselves on our dynamic partnerships with other universities, governmental agencies, non-profit organizations, and private companies. Our department is also home to a number of research centers tackling many of the most pressing environmental health issues facing our world today. Rollins students find a wide variety of work-study and other research opportunities through these research centers, individual faculty research projects, and our vast network of collaborative partnerships.

Students and alumni that are intersted in stregthening thier reseach and professional connections are encouraged to check out information on the Rollins Office of Career Development's website about MentorRollins and the Emory Chapter of the Atlanta Society of Mentors (ASOM).

Center for Children's Health, the Environment, the Microbiome and Metabolomics

Researchers at the Center for Children’s Health, the Environment, the Microbiome, and Metabolomics (C-CHEM2) conduct research to understand the complex interactions among components of the prenatal and postnatal environment—toxicant exposures, the microbiome, and the metabolome—and their impacts on birth outcomes, infant health, and neurodevelopment.

Center for Global Safe WASH

Emory is a recognized leader in the field of water, sanitation, and hygiene (WASH) research. The Center for Global Safe WASH (CGSW) focuses on increasing access to safe drinking water, adequate sanitation, and appropriate hygiene as part of a global strategy to break the cycle of poverty and disease in developing countries.


Climate@Emory is an inter-disciplinary, university-wide initiative to advance climate change scholarship, teaching, partnership, and engagement at Emory and beyond.

GEOHealth Hub

The Global Environmental and Occupational Health (GEOHealth) program from the Fogarty International Center (FIC) of the National Institutes of Health (NIH) aims to support the development of institutions in the low or middle income countries that will serve as regional hubs for collaborative research, data management, training, curriculum and outreach material development, and policy support around high local and regional environmental and occupational threats. Emory houses one of seven GEOHealth hubs in partnership with the Universidad Peruana Cayetano Heredia in Lima, Peru.

HERCULES Exposome Research Center

HERCULES is one of about 20 centers across the country dedicated to supporting all aspects of environmental health research at their home institutions and to developing collaborations with researchers across the country.  

Household Air Pollution Intervention Network

The Household Air Pollution Intervention Network (HAPIN) Trial is an international multi-center study aimed at assessing the impact of a liquefied petroleum gas cooking stove and fuel intervention on health. HAPIN Trial centers are located in four countries: Guatemala, India, Peru and Rwanda. 

Southeastern Center for Air Pollution & Epidemiology

Originally funded by USEPA, SCAPE is a joint research initiative between the Rollins School of Public Health at Emory University and the Schools of Civil and Environmental Engineering and Earth and Atmospheric Sciences at the Georgia Institute of Technology. The center was established to study air quality and the health effects of air pollution. It continues today as an umbrella for a variety of ongoing air pollution studies and provides faculty and students opportunities to share plans and ideas for new research in this area.
