Public Health Careers: What Can You Do With a Public Health Degree?
| 9 Min Read
Public health is among the most versatile and in-demand career paths. Open to healthcare and non-healthcare professionals, the field spans epidemiology, environmental science, policy, community education, global health and administration. Professionals in each area share a common bond: improving the health of entire populations versus individual patients.
Whether you are considering a career pivot or currently employed in the field and looking to qualify for advancement opportunities, Adelphi University’s online Master of Public Health (MPH) program prepares graduates for a range of specialized roles in one of the most diverse and rapidly growing fields. The 42-credit program pairs a CEPH-accredited generalist curriculum with hands-on fieldwork, giving graduates real-world experience alongside academic training. This guide covers common public health career paths, related salary data and the degree level required for specific roles.
What Careers Can You Pursue With a Public Health Degree?
Some public health roles involve research, data and analysis while others focus on community engagement, policy development or program management. Professionals in the field work in a range of settings, including government agencies, nonprofit organizations, hospitals, research institutions, international bodies and private sector companies.
The below list of public health careers reflects the full range of what the field offers. Each role requires a distinct focus and skill set, giving you a clear picture of where a public health degree can take you.
What Does an Epidemiologist Do?
An epidemiologist investigates the patterns, causes and spread of disease and injury in human populations. This role sits at the core of public health practice. Epidemiologists design studies, collect and analyze data and translate findings into recommendations that guide public health policy and response.
According to the U.S. Bureau of Labor Statistics (BLS), the median annual wage for epidemiologists was $83,980 in May 2024. Employment is projected to grow 16% through 2034, much faster than the average for all occupations. Most epidemiologists work for state or local government agencies, though hospitals, research universities and private sector firms also employ them in significant numbers. An MPH with a concentration in epidemiology is the standard entry path for this role. Adelphi University’s online MPH program builds this foundation directly into its required coursework, pairing Principles of Epidemiology with a dedicated Quantitative Analysis course so graduates enter the field with hands-on statistical training, not just an understanding of theory.
Health Educator and Community Health Worker
Health educators design and run programs that teach communities how to manage and improve their own health. They work in schools, hospitals, nonprofits and public health departments developing materials, running workshops and evaluating program outcomes. Community health workers often operate in similar settings, connecting underserved populations to care and serving as trusted bridges between health systems and the communities they serve.
BLS reported a median annual wage of $63,000 for health education specialists in May 2024, with 7,900 annual job openings projected through the decade. Demand is especially strong in community health centers, federally qualified health centers and organizations focused on health equity. An MPH strengthens eligibility for program director and senior educator roles that require demonstrated expertise in health behavior theory and program design.
Public Health Analyst
Public health analysts gather, manage and interpret data to support evidence-based decisions across health agencies and organizations. The work ranges from tracking disease surveillance metrics to evaluating the effectiveness of public health interventions. Analysts with strong quantitative skills often specialize in biostatistics or health informatics, applying statistical modeling to population-level health questions.
This role appears across federal agencies, state health departments, managed care organizations and research firms. An MPH provides the methodological foundation — epidemiology, biostatistics, research design — that employers look for in mid-career analyst positions. Entry-level titles include public health associate and data analyst. Senior roles carry titles such as program evaluator or health data scientist.
Environmental Health Specialist
Environmental health specialists study how physical surroundings affect human health. That work includes investigating contaminated water and air, assessing workplace hazards, evaluating the health risks of climate change and developing programs to reduce environmental exposures in vulnerable communities. It is a field where scientific rigor meets direct community impact.
BLS reported the median annual wage for environmental scientists and specialists in May 2024 was $80,060. Driven by increasing demand for climate-related health workers, employment is projected to grow 4% through 2034. Most environmental health specialists hold at least a bachelor’s degree. An MPH with an environmental or occupational health concentration positions graduates for leadership roles and consulting work at the intersection of science and policy.
Health Policy Advisor
Health policy advisors develop, analyze and advocate for policies that affect how healthcare is delivered and funded. They work with legislators, government agencies, think tanks, advocacy organizations and health systems, translating research into policy language and tracking the implications of proposed changes. This role requires both technical understanding of health systems and strong communication skills.
The American Public Health Association identifies policy advocacy as one of the central functions of the public health profession. Health policy advisors with an MPH — particularly those with a concentration in health policy or public health management — are positioned to move into director-level roles within agencies or nonprofit organizations that shape health legislation at the state and federal level.
Global Health Program Officer
Global health program officers design and manage health initiatives across international contexts, often working on disease prevention, maternal and child health, and nutrition within health systems in low- and middle-income countries. Employers include the World Health Organization, USAID, the CDC’s global programs, major nonprofits such as Partners in Health and bilateral aid agencies.
This role typically requires a graduate-level degree; an MPH with a global health or epidemiology concentration is the most common path. Program officers manage budgets, coordinate field teams, write grant proposals and produce reports for funders and partner governments. The work demands both technical public health knowledge and cross-cultural program management skills.
What Does a Public Health Administrator Do?
A public health administrator plans, directs and coordinates health services and programs at the department, facility or organizational level. These professionals are also referred to as medical and health services managers, and they work across hospitals, public health departments, community health organizations and government agencies.
According to BLS, the median annual wage for medical and health services managers was $117,960 in May 2024, the highest among the roles covered in this guide. Employment in the field is projected to grow 23% through 2034, with roughly 62,100 openings being added each year on average. The combination of strong salary data and rapid growth makes health administration one of the most compelling destinations for MPH graduates pursuing leadership tracks. Adelphi University’s online MPH reinforces this leadership track directly, pairing a Hospital and Health Care Finance course with a two-part capstone project that gives graduates real experience managing a public health initiative from proposal to completion before they graduate.
Salary Ranges Across Public Health Roles
Salaries in public health vary considerably by role, specialization, employer type and geography. The table below reflects median annual wages from the BLS Occupational Outlook Handbook, based on May 2024 data.
| Role | Median Annual Wage (May 2024) | Projected Growth (2024-2034) |
| Public Health Administrator | $117,960 | 23% |
| Epidemiologist | $83,980 | 16% |
| Environmental Health Specialist | $80,060 | 4% |
| Health Educator | $63,000 | 4% |
These figures represent the national median salary. Professionals working in major metropolitan areas, federal agencies or the private sector often earn above these benchmarks. An MPH can help increase earning potential by qualifying graduates for roles that require graduate-level credentials, particularly in administration, epidemiology and policy.
What Public Health Career is Right for You?
An MPH offers graduates the most direct route to specialized and leadership roles across the public health field. Entry-level positions in health education, community outreach and program coordination are accessible with a bachelor’s degree. However, roles in epidemiology, health policy, global health, environmental health leadership and administration consistently require or strongly prefer a master’s-level credential.
Adelphi University’s online Master of Public Health program equips graduates with the in-demand combination of analytical training, public health theory and practical experience that employers across sectors look for in mid- and senior-level hires. Its generalist curriculum spans epidemiology, biostatistics, health policy, environmental health and social and behavioral health, and culminates in a 180-hour practicum placement and two-part capstone project that let students apply coursework to a specific career path from the start.
What Makes Adelphi University’s Online MPH Program Stand Out?
Adelphi University’s online MPH pairs a CEPH-accredited, generalist curriculum with hands-on fieldwork designed to prepare graduates for immediate impact. The 42-credit program is delivered in 8-week terms and can be completed part time in as little as two years, with foundation coursework in epidemiology, biostatistics, health policy and program planning followed by electives such as community assessment, health informatics and program evaluation.
Every student completes a 180-hour practicum placement with a qualified preceptor, followed by a two-part capstone project, giving graduates a portfolio-ready public health project before they enter the job market. Courses are taught entirely by full-time faculty who bring direct field experience to small class sizes, so students get personalized instruction.
The program is built around practical support for working professionals. Applicants do not need to submit GRE or GMAT scores, and up to six transfer credits are accepted from other CEPH-accredited programs, helping students with prior graduate coursework finish faster. Students also have access to Adelphi’s Center for Career and Professional Development, which offers job-search tools, recruitment programs and job fairs geared toward public health careers. Adelphi’s 125-plus-year history, recognition from U.S. News & World Report, The Princeton Review and many other accolades underscore the institutional strength behind the degree.
