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.
