Online PhD programs in public health offer the ultimate convenience for students with family obligations or full-time jobs. Many also have the affordability and accreditation you need to make sure employers can trust the knowledge and skills you acquire. At the PhD level, however, most online public health programs are hybrid in nature. They allow you to take some of your coursework online, but require periodic campus visits to complete the full curriculum. While this is changing and more fully online programs become available, now is a great time to see what’s out there. This comprehensive guide will help you find the best hybrid or online PhD in public health for you. It outlines tuition costs, specializations, and coursework for the degree. Here’s a closer look at one school that offers the fully online public health PhD.

Walden University

Walden University

Walden University’s PhD programs in public health are designed for professionals who already hold a degree and have practical experience. The university offers two tracks: one is an accelerated curriculum for students with a Master of Public Health (MPH) or MS in Public Health. Students may choose a concentration in either Community Health Education or Epidemiology. Walden requires 88 quarter credits, a dissertation, and four residencies for the PhD. The second track is designed for those who hold at least a bachelor degree in any major field of study. This track offers the same focus areas, Community Health Education or Epidemiology. Students must complete 119 quarter credits, a dissertation and four residencies. Programs take from 5-7 years to complete. Applicants can transfer up to 43 total credits, shortening the time to complete the degree. What sets this program apart is Walden’s focus on advancing skills for a role as a scholar-practitioner among diverse populations. The PhD dissertation is designed for students seeking practical and effective solutions using Walden’s scholar-practitioner learning model. The dissertation is focused on developing a community health assessment and the creation of a program to address community goals. Applicants can take advantage of Walden’s unique limited-time savings offers that include $4,000 tuition grant.

Public Health Doctorates: PhD vs DrPH

Both doctoral programs serve distinct educational and career purposes. PhD programs in public health are designed for students more interested in scholarly research and publication. The PhD programs in public health culminate in a dissertation that can establish you as an expert in the field or as a researcher or university professor. While limited in number nationwide, these online programs offer the flexibility of synchronous and asynchronous training that fits your schedule.

DrPHs are geared toward working public health practitioners — professionals who want to reach the next level working in a more practical or clinical setting. The DrPH prepares you for leadership roles at private and public institutions. Studies focus on interdisciplinary collaboration and advanced training in fields including promotion, public policy, communications, marketing, and budgeting.

The following table offers a specific breakdown of the differences in these doctoral programs:

DrPH PhD programs in public health
Academic focus Evidence-based Research-based
Career track Clinical/professional Academia
Program type (common) Part-time Full-time

Accreditation & the Public Health PhD

Be sure that any doctoral program in public health you’re researching holds regional accreditation. Accreditation can cover an entire university or a specific public health program. Employers, publishers, and public health institutions want to ensure that candidates have completed degrees that conform to the academic standards set by professional organizations. These private, non-biased evaluation organizations offer accreditation services to universities on a voluntary level. There are serious ramifications if your target college is not accredited. For example, students at universities without accreditation may not participate in federal student aid programs. The accreditation germane to public health is offered by the Council on Education for Public Health (CEPH). Before enrolling it’s important to learn whether the university is accredited, along with accreditations for the PH department at the school.


Inside the PhD programs in Public Health Online

When gathering a list of potential PhD programs, be sure to compare the admission requirements, curriculum, total program costs, graduation rates, and where graduates have taken jobs. Have faculty members published, received honors or recognition in the field? What are your options for financial aid? The best decision is an informed decision. Here are key questions you need answered first:

What tracks are available in public health PhD programs?

At the PhD level, you’ll need to specialize. Individual programs may vary; you may enter a program that focuses on an aspect of your broader degree, or you can narrow your studies as you progress toward your dissertation or capstone. Here are two of the most common specializations at the PhD level:


Epidemiology is the study of chronic or infectious disease, how it impacts the community, the causes, and how to develop disease-prevention programs to address risks. Students undertake coursework and research assignments in factors including environmental hazards, infectious disease, terrorism or natural disasters. Students may examine issues at the community, schools, regional, national or global levels.

Research Methods

Community Health Education specializations are well-suited for students who have completed a master’s degree in public health. You’ll conduct studies of a target population, assessing shortcomings and the quality of life in the community. Following research, you’ll develop education programs to best-improve current service offerings. Notice to online students: the program may involve residencies.

In addition to these traditional specializations, you may find traditional campus-based programs that offer online elements focusing on the following areas:

Health Policy & Management

This concentration involves the study of health care policy and business. Students delve into courses on policy law and program planning. Students may opt for online or campus-based classes or hybrids involving night or weekend campus classes. Graduates are prepared to assume positions in public health care institutions at the local, state or federal levels.

Global Health

This PhD concentration combines population health measurement, epidemiology, advanced quantitative methods, implementation sciences, and impact evaluations. Implementation science is the study of key factors and critical conditions that lead to success – or failure – of a public health organization. Students use evidence-based methods to determine how to improve or implement solutions.


The field of biostatistics concerns the scientific evaluation of data from clinical populations, drug or treatment trials, and epidemiology findings in a search for more-effective solutions. The work is especially vital in informed decision-making at the organizational level. Coursework may include statistical study design, advanced regression analysis, and conditional probability.

What will you learn in a public health PhD program?

Every PhD program in the field is different, and they vary depending on your specialization. Here’s a detailed look at some of the courses in Walden’s online PhD programs in public health with a concentration in community health education, along with the skills on which they focus:
