Understanding the Master of Public Health Degree
The MPH curriculum develops competencies focused on population health, guided by standards set by the Council on Education for Public Health (CEPH). This professional training is rooted in five foundational disciplines that equip graduates with the analytical tools necessary for public health practice. These core areas ensure a standardized educational experience for all students entering the field.
The five core disciplines are:
- Biostatistics, which focuses on applying statistical methods to public health data.
- Epidemiology, the study of the patterns, causes, and effects of health and disease conditions in defined populations.
- Environmental Health Sciences, which examines how biological, chemical, and physical factors influence human health.
- Health Policy and Management, concentrating on the organization, administration, and financial aspects of healthcare systems and public health agencies.
- Social and Behavioral Sciences, which explores the role of social, cultural, and behavioral factors in health promotion and disease prevention.
Key Employment Sectors for MPH Graduates
MPH graduates apply their population-level perspective across a broad spectrum of organizations. The government sector, including federal, state, and local levels, remains a primary employer. Agencies like the Centers for Disease Control and Prevention (CDC) rely on MPH professionals for surveillance, outbreak investigation, and policy development. State and local health departments engage graduates in community services, health promotion campaigns, and emergency preparedness planning.
Non-profit organizations and Non-Governmental Organizations (NGOs), such as the World Health Organization (WHO) and domestic advocacy groups, offer roles focused on specific health issues or international development. Professionals in this sector manage programs, secure grant funding, and advocate for policy changes related to issues like maternal health or disease-specific research.
The private sector is a rapidly expanding area for MPH careers. This includes pharmaceutical and biotechnology companies requiring expertise in clinical trial design and post-market surveillance. Health insurance providers, consulting firms, and healthcare technology companies also hire graduates to analyze population data, manage risk, and improve quality and efficiency within health systems. Academic institutions and research hospitals employ MPH holders as researchers, program evaluators, and data analysts, contributing to the evidence base that drives public health interventions.
