DrPH Vs. Ph.D. in Public Health – What’s the Difference?

The difference between a DrPH and a Ph.D. is significant, although both are post-graduate degrees that denote expertise in a particular field. 

A Doctor of Public Health (DrPH) is a terminal degree designed for public health professionals who wish to pursue leadership positions. The curriculum for this degree is tailored to the needs of public health leaders. It focuses on study areas such as policy, management, research methods, evaluation, quantitative analysis, and other administrative skills. 

A Ph.D. in public health is a graduate degree program focusing on the health of individuals, communities, and populations. It involves the study of epidemiology and biostatistics, health services administration, environmental health sciences, community health education, global and public health policy, and much more. Graduates may work in various settings, such as hospitals, universities, research centers, or government agencies. With this degree, graduates gain the knowledge, skills, and techniques they need to become public health researchers, educators, policymakers, and leaders in the field. 

The Core Goal of DrPH and PhD

The core goal of the DrPH program is to prepare students to become leaders in their respective fields by emphasizing practice-based learning that enables them to apply theory to real-world problems. 

As such, students can easily enroll in online DrPH programs and earn their degrees by demonstrating proficiency in solving complex interdisciplinary public health problems, emphasizing advanced problem-solving skills that can be applied across multiple contexts. 

In contrast, a Ph.D. typically emphasizes advanced research methods that involve more theoretical aspects of one specific discipline like biology, biochemistry, etc. 

Although both degrees are intended for those interested in pursuing scholarly careers related to public health research and practice, each is designed for different audiences with different objectives for their degrees. One is focused more on practice than research, while the other focuses more on research than practice. 

Enrollment Requirement

The requirements to get started with a Doctor of Public Health (DrPH) and a Ph.D. in Public Health vary. Generally speaking, DrPH requires an accredited master’s degree in public health or a related field. Students are often required to have background knowledge in health services administration, health management, and environmental health.

For Ph.D., the students must have a master’s degree in relative subjects like biology and epidemiology. The Ph.D. may also require additional coursework such as population health, clinical research, or global health. 

Before enrolling in a Doctor of Public Health or Ph.D. in Public Health program, prospective students should review the individual requirements at their chosen institution to ensure they have completed all necessary credentials and coursework.

Course Work Requirement

A Doctor of Public Health (DrPH) requires a minimum of 60 semester credit hours beyond the master’s degree, with at least 30 semester credit hours in residence at an approved college or university. A dissertation is also required to complete the program and demonstrates research competency.

A Ph.D. or Doctor of Philosophy degree is usually awarded after a rigorous period of research and study. To receive this degree, students must produce an original research thesis contributing knowledge in the chosen field. 

Scope of Degrees

At the most basic level, a DrPH is designed to provide students with advanced knowledge and skills to become leaders in public health practice. In contrast, a Ph.D. is designed to prepare students for academic or research-focused careers. 

After completing a Doctor of Public Health (DrPH) degree, the possible fields of work are vast and varied. Depending on the particular area of focus for a DrPH graduate, opportunities may exist in the;

  • traditional public health settings such as local, state, or federal agencies
  • clinical or hospital settings, providing counsel and advice on public health issues
  • private corporations that have a stake in public health-related services and products
  • non-governmental organizations (NGOs) focused on addressing particular public health needs

Some DrPH graduates also become consultants for private firms or government agencies, designing policy initiatives and interventions to improve public health outcomes. 

After completing a Ph.D. in public health, graduates can pursue various career paths. With the knowledge gained from their studies, they can enter into 

  • Research-based roles such as analysts, epidemiologists, or biostatisticians
  • Colleges and medical universities, as professors
  • Public health departments as managers for prevention and wellness
  • Healthcare administration for formulating policy and playing advocacy roles

Difference in Curriculum 

In terms of curriculum, the DrPH focuses on advanced subjects like epidemiological methods, research design, and data analysis. Moreover, students learn about health communication, policies, management, leadership, organizational theories, and global health ethics. 

It also includes courses in quantitative methods such as biostatistics, economics, and social sciences. The primary goal of this degree is to produce public health practitioners who can solve real-world problems by applying their knowledge of evidence-based practices to find solutions. 

On the other hand, a Ph.D. in Public Health provides students with an advanced understanding of scientific principles related to public health. 

Ph.D. courses may focus on environmental health sciences, infectious diseases, population or community health studies, nutrition, or other subjects related to improving healthcare outcomes. 

In addition to coursework, doctoral candidates must complete supervised research projects leading to a dissertation contributing new knowledge or advancements within their chosen field of study. 

Salary Differences 

The salaries of Doctor of Public Health (DrPH) and Doctor of Philosophy in Public Health (Ph.D.) degree holders vary depending on several factors, such as experience, geographic location, and type of employer. 

DrPH degree holders are likely to earn comparatively higher salaries than Ph.D. degree holders because it is a more advanced level of education and training. Additionally, those with a DrPH degree have more opportunities for career advancement than those with a Ph.D. in Public Health. 

According to PayScale, the average salary range for DrPH holders is $76,000 per annum.


In conclusion, the difference between a DrPH and a Ph.D. is significant. The DrPH is intended for public health professionals who wish to pursue leadership positions within their field, while the Ph.D. typically focuses on research methods in one specific discipline. Each degree prepares students for careers related to public health, and neither should be considered superior to the other; it all depends on the individual’s goals and objectives.
