Public health professionals play a vital role in protecting communities, cities, states and the nation by improving access to care and shaping policies that influence population health outcomes. From responding to localized disease outbreaks to addressing large-scale environmental risks and chronic conditions, the field of public health focuses on prevention, data-driven decision-making and long-term impact.
A Master of Public Health (MPH) degree develops the skills professionals need to assess health trends, design interventions and lead initiatives that improve quality of life at the local, national and global levels. With its broad scope and emphasis on applied problem-solving, this degree prepares students for a wide range of career paths across healthcare, government, nonprofit and research settings.
Eastern Washington University’s MPH – General online program is designed to prepare students for leadership roles in public health practice. With a curriculum that emphasizes population health, policy and data analysis, the program supports professionals seeking to advance their careers while continuing to work.
Epidemiologist
Epidemiologists study patterns of disease and health conditions within populations to understand causes, risk factors and prevention strategies. They collect and analyze data on infectious diseases, chronic illnesses and environmental exposures to inform public health responses and policy decisions.
Professionals in this role often work for government agencies, hospitals, research institutions or public health departments. Key responsibilities include designing studies, interpreting health data and communicating findings to stakeholders. Strong analytical skills, attention to detail and experience with statistical tools are essential. Employment demand for epidemiologists remains steady and is expected to grow by as much as 16% by 2034, as public health agencies continue to prioritize disease surveillance and preparedness.
Health Education Specialist
Health education specialists focus on promoting healthy behaviors through education, outreach and community-based programs. They assess community needs, develop educational materials and implement initiatives to improve health literacy and reduce preventable conditions.
These professionals commonly work in nonprofit organizations, healthcare systems, public health departments and educational institutions. Responsibilities may include program planning, community engagement and evaluation of behavior-change outcomes. Career growth opportunities exist for those who move into leadership roles overseeing larger public health campaigns or managing multidisciplinary teams. Health education specialist roles are projected to grow at an average rate of 4% over the next decade.
Public Health Program Manager
Public health program managers oversee initiatives to address health challenges in rural communities or broader populations. They are responsible for planning programs, managing budgets and coordinating efforts among stakeholders such as healthcare providers, policymakers and community organizations.
This leadership-focused role requires strong organizational and communication skills. Program managers also evaluate outcomes to ensure initiatives are effective and aligned with public health goals. Public health program managers work for government agencies, nonprofit organizations or healthcare systems and are prepared to advance into senior leadership or policy-focused roles.
While there are no statistics specifically for public health program managers, the U.S. Bureau of Labor Statistics provides outlooks for social and community service managers, who oversee initiatives that support public well-being. There is a steady demand for these leaders among community action and public health organizations, contributing to an anticipated 6% growth rate for social and community service managers, which is faster than the national average for all occupations.
Biostatistician
Biostatisticians apply statistical methods to analyze health data and support research, clinical trials and public health decision-making. Their work helps identify trends, evaluate interventions and inform evidence-based policies.
Biostatisticians develop statistical models, interpret large datasets and create data visualizations to communicate findings. Pharmaceutical companies, government agencies, academic research institutions and public health organizations often employ biostatisticians for a wide range of positions that support population health initiatives. Demand for statistical specialists is projected to grow by 8% through 2034 as data-driven approaches continue to shape healthcare and public health planning.
Environmental Health Scientist
Environmental health scientists examine how environmental factors, such as air quality, water safety and chemical exposure, affect human health. Their work supports efforts to reduce environmental risks and improve regulatory standards.
They conduct risk assessments, monitor environmental hazards and contribute to the development of safety guidelines. Employers include ecological protection agencies, local health departments and consulting firms. This career path is especially relevant as communities address climate-related health concerns and environmental sustainability.
The demand for environmental scientists and specialists remains steady, including positions focused on the impact of environmental shifts on public health. The field is expected to grow by 4% through 2034, which aligns with the national average for all occupations.
