Should I Pursue a Ph.D. in Public Health Online?
A Ph.D. program challenges students intellectually and emotionally, and it is important to consider how earning a public health doctorate benefits personal and professional goals. Here are four primary reasons why you might decide to matriculate into an online Ph.D. program in public health: to teach on topics of public health at the undergraduate or graduate level; to conduct public health research in academia; to work as a public health researcher for a government, nonprofit, or private organization; or to be more competitive for an administrative position in public health.
Perhaps the most obvious reason to get a Ph.D. is to work in academia. Most academic positions in the field of public health require a Ph.D. as confirmation of a professor's knowledge and experience. However, other positions exist in academia where having a doctorate may make you a more competitive candidate. For instance, many research think tanks, government organizations, or nonprofit groups often hire public health researchers and possessing a Ph.D. indicates an increased level of training and can make you a more desirable applicant.
In addition to professional reasons, students pursue a doctorate in public health for a multitude of personal convictions, including an ongoing passion for analyzing the health and risks of a population, enjoyment reading scientific articles and books in the field, or learning about methods of scientific analysis concerning larger populations.
What Can I Do with an Online Ph.D. in Public Health?
Graduates with an online doctorate in public health can access a wide variety of careers, including working in healthcare facilities, government positions, academia, and the public sector. Hospitals and clinics employ health services administrators and biostatisticians. Universities need public health professors and researchers. Health departments of state and local governments, research institutions, and nonprofit organizations often search for public health analysts, health policy analysts, and epidemiologists.
Typical public health careers, like those listed above, usually involve either teaching, research, or some combination of the two. Professors and assistant professors of public health balance a combination of teaching and research responsibilities. Public health analysts, epidemiologists, and biostaticians focus primarily on research, which includes laboratory work, statistical analysis, and survey research.
Aside from these more common paths, a degree in public health can also unlock career opportunities in the fields of emergency management, nutrition, community health work, occupational health and safety, community service management, nursing, and industry management and leadership. Some of these other options may require combining a public health degree with another specialty.
Industries search for innovative leaders with an advanced degree in public health, particularly if the industry carries a health-related product or deals with public health policy. Application of the advanced skills and knowledge learned through the acquisition of an online Ph.D. in public health correlate to positions that may require data analysis, writing research reports, and an understanding of community health issues and how they might be improved.

Online Ph.D. in Public Health Program Overview
Several factors can influence choosing the right online public health Ph.D. program, including the research specialities of faculty, what types of courses or certification programs offer, what type of capstone project is required, and cost of tuition. Perhaps the most important factor is what types of careers students desire, since public health programs emphasize either practice or research, preparing students for different career paths depending on their chosen emphasis.
What is the Difference Between a Dr.PH. and Ph.D.?
Those interested in pursuing a Ph.D. in public health can choose between a Doctor of Philosophy (Ph.D.) or a Doctor of Public Health (Dr.PH.). The primary difference between these two types of programs is that a Ph.D. in public health focuses more on research methods and theory while a Dr.PH. is a professional degree that emphasizes the practical application of public health principles.
An individual looking toward work as a researcher in a medical lab, research institution, or university may prefer a Ph.D. program, whereas a Dr.PH. better suits an individual who hopes to work as a manager, director, or consultant in a health department or public health program.
Curriculum and graduation requirements can differ between these two types of doctorate programs. Ph.D. programs require writing and defending a dissertation in order to graduate; Dr.PH. programs may require an applied practicum as an alternative or in addition to the dissertation. Practicum components usually ask students to complete a project for a healthcare facility or organization to advance public health practice, similar to practicum experiences required by masters of public health programs. Both types of programs take around four years to complete, requiring about 55-65 credits of coursework.
Application Requirements and Admission Criteria
Applicants to online Ph.D. and Dr.PH. programs have typically completed a master's degree, preferably in public health. Some programs also accept students holding a master's degree in a subject outside of public health while other programs consider these students on a case-by-case basis. Yet other programs offer a combined MPH and Ph.D. of public health degree, in which case students enroll immediately after graduation from undergraduate study.
Most online doctorate programs in public health also require GRE scores, with a minimum combined score of 1000. Other application materials include a statement of purpose, resume or CV, transcripts from previous institutions demonstrating a GPA higher than 3.0, and three letters of recommendation. Some Dr.PH. programs may also require work experience in the health field.
Curriculum
Online doctorate programs in public health are typically structured by four main elements: foundational courses, concentration core courses, electives, and dissertation credits. Most public health programs allow students to further specialize in an area under the umbrella of public health such as biostatistics; epidemiology; health promotion and behavior; health services and policy research; or environmental health.
After taking foundation courses in topics such as advanced research methods, statistical analysis, and public health ethics, students often take courses of their choice in an area of concentration and elective courses. Core course requirements usually total 18 credit hours while concentration and elective courses equal around 30 credit hours. Most Ph.D. programs also require that students pass a comprehensive or qualifying exam before advancing to candidacy. After that, students continue on to complete practicum and/or dissertation research and writing hours. Potential courses for an online Ph.D. in public health are listed below.
