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 stress 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 I is designed for students with a Master of Public Health (MPH) or an MS in Public Health.
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.
This sequence represents the minimum time to completion. For a personalized estimate of the number of your transfer credits that Walden would accept, call an enrollment advisor at 855-646-5286.

Students approach statistics from a problem-solving perspective with emphasis on selecting appropriate statistical tests for a research design. Students use statistical software to derive statistics from quantitative data and interpret and present results. RSCH 8110 or RSCH 7110 or RSCH 6110, and RESI 8401.)
By addressing current trends and future applications in public health research, students develop advanced competency in health informatics and surveillance in this course. The key issues of data standards and integration, vocabularies and data transmission protocols, health information technology, surveillance systems, and the application of geographical information systems to situation awareness are addressed. Other topics include information architecture, public health records, electronic medical records, electronic health records, health information exchange, and database design, as well as information storage, security, and privacy. RESI 8401.)
In this course, students explore leadership models and theories, the core principles of public health leadership, and the application of systems thinking to public health. They examine how to create strategies and solutions that efficiently utilize public health and healthcare resources. Students also discuss descriptive and prescriptive systems, focusing on the application of these processes to current public health issues and challenges at the organizational and community levels.
