Build your skills and conduct important research in your field with our online PhD in Public Health degree program.
Infectious and chronic diseases can devastate entire communities. The Epidemiology specialization broadens your understanding of how these diseases affect populations and explores strategies for maintaining the health of communities. Study how the prevalence of chronic diseases like cancer and diabetes can distress communities and learn to create education programs that can help prevent the spread of chronic disease. As part of your coursework, you will conduct an epidemiological field study that includes original research.
Track II is designed for students who hold a bachelor’s degree or higher in an academic discipline other than the public health field. In addition to specialization coursework, Track II explores public health fundamentals including case studies and research methods, public health management, and environmental health.
You may be eligible to transfer a maximum of 60 graduate-level credits into the program.
Walden students have up to 8 years to complete their doctoral program unless they petition for an extension.
In general, students are continuously registered in the dissertation/doctoral study course until they complete their capstone project and it is approved. This usually takes longer than the minimum required terms in the dissertation/doctoral study course shell.
To complete a doctoral dissertation, students must obtain the academic approval of several independent evaluators including their committee, the University Research Reviewer, and the Institutional Review Board; pass the Form and Style Review; gain approval at the oral defense stage; and gain final approval by the Chief Academic Officer. Students must also publish their dissertation on ProQuest before their degree is conferred. Learn more about the dissertation process in the Dissertation Guidebook.
