Master of Science (ScM) in Environmental Health
Offered By: Department of Environmental Health and Engineering
Onsite | Full-Time | 2 years
About the ScM in Environmental Health Program
The ScM is intended for students with a serious interest in pursuing research or field work in environmental health. Often these students have previously worked hands-on in laboratory, field, or population-based investigations and would like to build upon that experience.
Following one year of course work, students conduct original research under the direction of a faculty mentor which results in a formal thesis.
Graduates of the program are well-prepared to pursue doctoral degree programs and are also competitive for positions in the private sector, federal agencies, and non-governmental organizations.

Areas of Interest
The Department offers courses in the following areas:
Food Systems, Water and Environmental Sustainability
Courses in Food Systems, Water and Environmental Sustainability cover the factors that are driving current changes in the global environment and how they can lead to adverse effects on human health at individual and population levels. Through coursework and seminars, students will be exposed to a range of sustainability topics relating to food systems, water quality, use and re-use, the built environment and the multiple impacts of climate change. Research interests can include chemical and biological threats to food safety and water quality and approaches to effective intervention/prevention. This foundation can be used to support plans for subsequent doctoral (e.g. PhD, JD) level training or to pursue a career in government or the private sector. Students interested in this area may also complete the course requirements to receive the Certificate in Food, Environment and Public Health.
Health Security
Courses in Health Security cover domestic and international health threats, including epidemics, natural disasters, technological accidents, and intentional attacks. Students examine major organizations and initiatives designed to prevent, detect, and respond to health security threats; assess the current status of health security preparedness; and evaluate strategies to enhance health security. These courses are designed for individuals who would like to begin careers in public health and healthcare preparedness, global health security, outbreak and epidemic management, disaster response, and related fields. A subset of courses are taught by faculty from the Johns Hopkins Center for Health Security and informed by the Center’s two decades of scholarship and advocacy on health security policy.
Population Environmental Health
Courses in Population Environmental Health are for students whose research interests involve the use of epidemiologic methods to investigate of the impact of environmental hazards on the health of communities and high-risk populations. Courses in this area provide a strong foundation in epidemiology and biostatistics and the pathways through which environmental chemical and biological exposures lead to detrimental health outcomes. These courses offer skills needed for the use of statistical approaches and introduce students to quantitative skills used in epidemiologic research. Research interests can range from the use of epidemiology to investigate associations between exposure and adverse health outcomes to its applications in risk assessment and environmental health regulatory processes. These courses can be used to support plans for subsequent PhD-level training, applying to medical school with master’s-level research experience or to pursue a career in government or the private sector. Students interested in this area may also complete the course requirements to receive the Certificate in Risk Sciences and Public Policy.
Pre-med
Pre-med courses provide the foundation for students planning to attend medical school. These courses provide a strong understanding of statistics and epidemiology. Elective courses in physiology, advanced toxicology, and environmental and occupational disease not only emphasize knowledge covered on the MCAT but they also differentiate graduates from the typical medical school applicant. Ideal candidates present with a strong foundation in the basic sciences and math.
Toxicology for Human Risk Assessment
Courses in Toxicology for Human Risk Assessment are designed to match the needs of students with research interests that extend from laboratory-based study of the toxicological and pathophysiological mechanisms of environmental chemical and biological agent exposures to the methods for applying toxicology data to human risk assessment and the development of regulatory policy. Students interested in these courses should have strong backgrounds in the basic sciences and be considering subsequent PhD-level training, applying to medical school with master’s-level research experience, or who may decide to pursue a career in government or private sector research positions. Students interested in this area may also complete the course requirements to receive the Certificate in Risk Sciences and Public Policy.

Admissions Requirements
For the general admissions requirements see our How to Apply page.
Standardized Test Scores
Standardized test scores (GRE, MCAT) are optional for this program. The admissions committee will make no assumptions if a standardized test score is omitted from an application, but will require evidence of quantitative/analytical ability through other application components such as academic transcripts and/or supplemental questions. Applications will be reviewed holistically based on all application components.
Tuition and Funding
The Master’s Tuition Scholarship is available to students in good academic standing in a two-year, full-time master’s program. The MTS is a 75% reduction in tuition for year two of an eight-term program. Students have the option of distributing the scholarship entirely in their second year of study or receive a 25% reduction in tuition their first year and 50% in their second year.
