Featured PhD in Public Health Courses
Communicable Disease Epidemiology
This course covers principles and methods of communicable disease epidemiology. Topics include history of communicable disease control, infectious disease definitions and terminology, the epidemiologic triad, dynamics of transmission, laboratory diagnosis, outbreak investigations, disease surveillance, immunity, vaccines, and pandemics. Case studies are used to investigate vaccine-preventable diseases, respiratory diseases, sexually transmitted diseases, zoonotic diseases, diarrheal diseases, and antibiotic-resistant infections.
Environmental and Occupational Epidemiology
This course provides students with the key health effects of environmental and occupational exposures and the epidemiologic methods used to identify and estimate those effects, including addressing equity-related barriers. Students learn about environmental and occupational exposures (including water and air pollution, food contamination, ionizing radiation, persistent environmental pollutants, and emergent environmental exposures) and key methodological issues relevant for these exposures in population studies (including study design, exposure assessment and biomonitoring, disease clusters, dose-response relationships, susceptibility, geographic analysis, and evidence synthesis). Students will also learn the major health consequences and increased health risks of climate effects (including injuries, heat-related illness and death, and exacerbations of respiratory and cardiovascular disease).
Policy and Law for Environmental and Occupational Health
This course will explore the legal and regulatory frameworks for environmental and occupational health both in the United States and select additional countries. The roles of different levels of government in the development of environmental and occupational policies and laws will be addressed through an exploration of historical and contemporary examples. Students will gain experience in evaluation of current laws and regulations and develop strategies for addressing environmental and occupational health issues. Some of the topics covered will include evidence-based decision-making, environmental justice, and the role of climate change in health policy and law.
Advanced Program Evaluation
The course provides students interested in pursuing a public health doctoral-level degree with the advanced competencies necessary to evaluate public health programs. This course will emphasize public health practice and is designed to assist students in understanding how to plan, conduct, and report on a program evaluation. Students will learn the importance of abiding by the program evaluation standards and evaluator guiding principles. These are fundamental to ensure students complete evaluations with integrity and utility. Students will learn the importance of evaluation theory and the relationship between evaluation theory, program theory, and public health change theories.
Fundamentals of Mapping and Geographic Information Systems for Public Health
This course enables students to acquire, manipulate and effectively display spatial data by introducing principles, methods, and techniques used in public health to help foster decision and policy-making based on the visualization of data. Students will further understand how public health researchers and practitioners can increase the impact of their work by using geographic information systems (GIS) to convey information and synthesize data from multiple sources. Using basic GIS concepts, such as coordinate systems, layering, buffering, joining, merging, and aggregating spatial data, conducting spatial queries, and appropriate visualization of spatial data, students will be able to visualize, analyze, and interpret data in an accessible and useful way.

Epidemiological Investigations
This course introduces epidemiologic methods used to solve health related problems. Students gain knowledge in clinical, social and field epidemiology through case studies of actual epidemiological investigations. Methods that are critical to epidemiological investigations are presented, such as clinical trials, online survey research, matched case-control studies, and traceback studies. Topics will range from cancer and diabetes to HIV and COVID-19.
Lifestyle and Chronic Diseases
In this course, students explore how lifestyle and related risk factors influence chronic diseases, also called noncommunicable diseases. Topics include the role of diet, nutrition, physical activity, sleep, stress management, and substance use (tobacco, alcohol, and drug use) on the epidemiology of heart disease, diabetes, cancer, and asthma. Through development of an evidence-based intervention to improve a lifestyle behavior, students evaluate the use of theories of health behavior change, measurement techniques, screening approaches, and prevention of chronic diseases.
Community Health Assessment
This course covers community health assessment and its application to program planning. Students learn to identify and prioritize public health issues, then assess and utilize community resources to address them. Topics include measuring selected determinants of community health, evaluating community assets, applying data sources, and developing a community health assessment plan. Students will discuss approaches to synthesizing findings to identify priority health needs and consider dissemination strategies to maximize positive social change.
Advanced Public Health Policy and Advocacy
In this course, students examine the role of federal, state, and local government in the assurance of public health through health policy and law. Consideration is given to contemporary policy, law, and regulatory issues arising in public health practice, as well as to the economics and financing of public health programs. The advocacy, political, and creative process in the formulation, implementation, and modification of health policy are examined and discussed. Students also learn how to structure and write a health policy brief, which will provide students with experience integrating scientific information, legal, and regulatory approaches, ethical frameworks, and varied stakeholder interests in policy development and analysis.
Grant Writing and Review for Public Health Research
In this course, students investigate the multiple funding sources of public health research. Students analyze grant-writing strategies and the advantages and disadvantages of various financing options. Students will be responsible for writing a mock public health grant proposal to support a real-world research topic. In addition, students will be exposed to the grant approval review process and gain experience in grant review and evaluation.

These are ranges of what a student can expect in terms of time and tuition cost to complete a degree. It does not include other fees, nor is it adjusted for tuition increases over time. Walden faculty has concluded that generally students who do not complete their program in eight years are unlikely to complete and only allow students to exceed that time frame when a student petitions for an extension and provides good reason for the delay and assurances that obstacles to completion can be overcome. Time is calculated using the time allowed for each semester or unit that the student completes. Students are encouraged to work continuously during the program so as not to extend the time needed to complete the degree as work can become stale and students lose focus. Students who earn two grades of “Unsatisfactory,” who repeatedly drop a course before a semester or unit has been completed, or are unable to complete in the eight year time frame, should expect that they may be dismissed from the program. Walden believes that it is in the best interest of a student who is unable to complete the degree in the stated ranges to strongly consider withdrawal or obtaining a lesser degree.
Time to completion and cost are not estimates of individual experience and will vary based on individual factors applicable to the student. Factors may be programmatic or academic such as tuition and fee increases and/or the student’s transfer credits accepted by Walden; program or specialization changes; unsuccessful course completion; credit load per term; writing, research and editing skills; use of external data for their doctoral study/dissertation; and/or individual progress in the program. Other factors may include personal issues such as the student’s employment obligations; care giving responsibilities or health issues; part-time vs. full-time enrollment; leaves of absence; and/or other personal circumstances.
Tuition and fees are subject to change. Books and materials are not included. Students may incur additional costs for remedial writing assistance, if necessary.
