Epidemiology Programs
Within four degree programs (three master's and one doctoral), students have opportunities to engage directly with faculty, study internationally, and complete practicum experiences in the field.
Students in the PhD and ScM programs will choose from eight different tracks to focus their study and research. Students in the MHS and Bachelor's/MHS programs will choose from two different paths to focus their study. Additionally, there are several pre- and postdoctoral training programs available.
Our students graduate with marketable skills and real-world experience, ready to make an impact, from the #1 school of public health.
Master of Health Science (MHS)
The MHS is designed for students who want to gain quantitative skills to participate in research or the translation of research into practice.
Master of Science (ScM)
The ScM is designed for students who want to gain advanced quantitative skills to conduct research combined with a mentored experience in applying these skills in a thesis project.
Doctor of Philosophy (PhD)
Training is offered through a core methodologic sequence with the addition of more focused courses in specialized areas. Most training areas of concentration require specific courses. Students are expected to tailor their curricula, working with their advisers to create a comprehensive plan of study and research.
Bachelor's / Master of Health Science (MHS)
The Bachelor's/Master of Health Science MHS combined degree program prepares students for further graduate work or prominent careers in research and science. It is an opportunity for undergraduate students at Johns Hopkins University who are majoring in Public Health Studies.
