Doctor of Public Health

Environmental and Occupational Health


The Doctor of Public Health (DrPH) Program in Environmental and Occupational Health (EOH) is designed to develop public health leaders who are skilled in the identification, evaluation and control of environmental and occupational stressors and promotion of health and wellness. Within EOH "environment" is broadly interpreted and can include neighborhoods, worksites, cities, regions, nations, and the planet, and include chemical, physical, and biological stressors. Areas of specialization in EOH include (but are not limited to) built environment; toxicology and risk; and occupational health and wellness. Graduates will develop a strong knowledge base in the environmental and occupational health sciences and will be prepared to hold leadership positions in public health practice at the local, state or national level and in academia.

In addition to the general admission requirements for the DrPH program, the Focus Area in Environmental and Occupational Health requires the following:

  • MPH or MS in environmental or occupational health or a related discipline. If the applicant does not meet this requirement, students must take EHOH 6618 and 6619 and two of the following three courses: EHOH 6616, 6617 and 6620, or the equivalent during the first year of the program as co-requisites. Students must have prior graduate-level coursework in the five core areas of public health (Epidemiology, Biostatistics, EOH, Health Systems, Management and Policy, Community and Behavioral Health). Co-requisite credits are in addition to the 67 credits required for the DrPH degree. To determine if previous coursework meets the co-requisite requirements, students are advised to meet with the Director of the EOH DrPH program.

DrPH students in the EOH Focus Area will follow the curriculum structure outlined for all DrPH students:

12 hrs - Focus Area - will include the following:

Advanced Methods in Environmental & Occupational Health (2 credits). This course will cover advanced methods in survey design, environmental sampling, risk assessment, biomarkers and exposure assessment and focus on use of and issues associated with analysis of secondary datasets.

Advanced Field Investigations in Environmental & Occupational Health (1 credit). This course will build on the Advanced Methods in EOH course and provide practical field and laboratory applications. Field investigations will include sampling design, sample collection (e.g. air, water, soil, questionnaire), analysis and interpretation.

Geographic Information Systems (3 credits). Students will take EHOH6621 or the equivalent, an introduction to Geographic Information Systems, including the use of GIS software, mapping, geocoding and data analysis. If a student has previously completed an introductory GIS course, an advanced GIS course may be substituted.

Advanced Biostatistics (6 credits). Students will take BIOS 6611 and 6612 or equivalents to acquire advanced biostatistical skills. With permission of the student’s advisor, advanced biostatistical coursework may be substituted such as structural equation modeling, applied regression analysis, Hierarchical Linear Modeling (HLM), principal component or factor analysis, and mixed-model methods.

9 hrs - Selective Credit Hours - will build the student’s specific area of expertise, leading to the qualifying exams and dissertation. Examples of areas of specialization for EOH include (but are not limited to) the following: built environment, cancer prevention, climate change and health, worksite wellness, total worker health, exposure assessment, and toxicology. Courses must be selected in consultation with the student’s advisor, and relevant electives may be taken at any CSPH campus.

6 hrs - Minor - Public Health Electives - Elective courses in the selected minor area of study. The minor area must be in one of the five core areas of public health, excluding the major focus area. These include: biostatistics, epidemiology, environmental health, community and behavioral health, and health systems, management and policy. These courses will be taken in the School of Public Health.

4 hrs - DrPH Seminar - 4, 1 credit hr semesters of the DrPH seminar. Students will be required to attend the bi-monthly seminar for the first 4 semesters of their tenure in the program. The DrPH seminar will cover topic areas across all five concentrations of public health (i.e. biostatistics, community and behavioral health, environmental health, epidemiology, and health services, management and policy) while addressing the core DrPH competencies related to advocacy, communication, community/cultural orientation, critical analyses, leadership, management and professionalism/ethics. The seminar will include a combination of guest speakers on relevant topics, directed reading and discussion, and student presentations of areas of interest and work in progress.

3 hrs - Leadership - A course on leadership development, taken in the School of Public Health or, with permission, at another affiliated school. This CSPH Leadership course is intended to provide a foundation for emerging public health leaders that will include taking leadership from theory and principle to action and practice in contexts of the individual, team, organization and community.

3 hrs - Management - A course on principles of management or organizational communications, taken in the School of Public Health or elsewhere with permission.

3 hrs - Proposal Writing - The overall goal of this requirement is to develop skills in preparing high quality, successful, research or practice grant applications. Students will become familiar with different granting mechanisms (e.g., NIH, CDC, foundations) and develop grantsmanship skills, including the ability to formulate research and practice plans and write at a high level of quality. This is a closely mentored and intensive activity that is intended to lead directly to the submission of a grant application.

2 hrs - Directed Reading - In preparation for written and oral comprehensive exams, each student will develop, in consultation with their examination committee, a directed reading list in the area of their dissertation research. This activity is intended to lead to the student becoming an expert in their specific area of research, including understanding of the historical development of the specific area, current research findings, and current practice in the area. Reading will address current epidemiological understanding of the area, methodological aspects of the area, theoretical underpinnings of behavior related to the area, and current practice in the area. For example, in the area of physical activity, upon completion of this activity, a student would be expected to have a thorough understanding of epidemiological evidence supporting or disputing a relationship between physical activity and disease etiology, natural history, and prognosis, physiological/psychological mechanisms for the relationship between physical activity and health/disease status, social, environmental and system level determinants, theoretical approaches used in understanding determinants of physical activity behavior, methods for assessing levels of physical activity, and current practices in developing programs for increasing levels of physical activity. The written and oral comprehensive exams will take place upon completion of directed reading.

4 hrs - Practicum - All DrPH students must engage in a minimum of 240 hours of fieldwork. This will usually be completed with an agency outside of the School of Public Health (e.g., local health department, state health department, volunteer organization, etc.). The fieldwork experience should address most, if not all, of the core DrPH competencies (Advocacy, Communication, Community/Cultural Orientation, Critical Analysis, Leadership, Management, Professionalism & Ethics).

21 hrs - Dissertation - Following completion of the written qualifying exam (see Exams/Dissertation tab), students will complete 21 dissertation credits during which time they prepare and defend their dissertation proposal, complete their dissertation research, and complete and defend their written dissertation.

It is expected that formal coursework will take approximately 2 years to complete. As students complete required coursework and practicum hours, they will advance towards independent research for their dissertation. In this process, students will complete written and oral qualifying exams.

Dissertation  

The dissertation will be of an applied nature and must demonstrate the student's ability to conduct independent research on a contemporary public health issue. The student is expected to examine and analyze a problem in public health practice that has readily identifiable beneficiaries and constituents. The dissertation committee will work with the student to identify appropriate areas of investigation. The project will involve a written product that comprehensively addresses, generates, and/or interprets and evaluates knowledge applicable to public health practice. 

 The written dissertation document may be one of several forms depending on the nature of the scholarly work, but should be of publishable quality and must demonstrate rigorous analytic strategies. It will typically take one of two forms: (1) a unified traditional dissertation, or (2) three publishable papers plus, at a minimum, introduction and conclusion chapters. The dissertation will be defended publicly and must be approved by the dissertation committee before the degree of DrPH is conferred.  

Dissertation Committee  

Each student will form a 5 member dissertation committee to guide their dissertation research including the directed reading, written comprehensive examination, dissertation research proposal, oral comprehensive examination, conduct of research, and completion and defense of the dissertation. The committee chair must be have a primary faculty appointment from the focus area department. The student's main mentor must have a primary or secondary appointment in the Colorado School of Public Health. The mentor may not be the Chair of the dissertation committee. In addition, the committee as a whole must meet the following minimum criteria:

1. Two members must be program core faculty in the FOCUS AREA department.
2. One member must be from outside the FOCUS AREA department.
3. One member must be from the practice community.

A Committee Membership form should be completed that designates committee membership and is signed by Chair and Mentor of the committee as well as Program Director. The final form should be submitted to the Program Director for approval prior to beginning the Directed Reading.

Directed Reading (2 credit hrs)

DrPH Directed Reading course is intended to help prepare DrPH students for their comprehensive exams and dissertation research. This activity is intended to result in th student being an expert in their specific area(s) of research, including understanding of the historical development of the specific area(s), current research findings in the specific area(s), and current practice in the areas. Readings will address current epidemiological understanding of the area, methodological aspects of the area, theoretical underpinnings of behavior and/or policy related to the area, and current practice. For example, in the area of physical activity, upon completion of this activity, a student would be expected to have a thorough understanding of epidemiological evidence supporting or disputing a relationship between physical activity and disease etiology, natural history, and prognosis, physiological/psychological mechanisms for the relationship between physical activity an health/disease status, social, environmental and system level determinants, theoretical approaches used in understanding determinants of physical activity behavior, methods for assessing levels of physical activity, and current practices in developing programs for increasing levels of physical activity.  

Prior to enrolling in the course and with guidance from the committee, the student will:

  • Select at least 2 areas of focus that are in line with the student's dissertation area of study. Compile an extensive reading list in these select areas.
  • The reading list should include seminal readings, reviews, meta-analyses and key original pieces of work.
  • Have the reading list reviewed and approved by the dissertation comittee. Committee members may choose to add/delete various readings from the list.

Once the initial reading list is finalized, the student may enroll in the DrPH Directed Reading course and will be expected to complete an annotated bibliography of the full reading list within the designated time span (i.e. one or two semesters as described above). The final reading list should include approximately 75-100 readings. The written exam will take place upon completion of directed reading.

Written Comprehensive Exam

Upon completion of the directed reading course, the student will schedule their written comprehensive exam. The student will have 2 weeks to provide written answers. The exam will include 3-5 essay questions written by the dissertation committee that incorporate DrPH competencies (both general and Focus Area specific) and the areas covered in the student's Directed Reading. Responses are expected to be in-depth with citations and may be of publishable quality (such as a literature synthesis). Total written response should be approximately 20-30 single-spaced pages. The committee will grade (i.e. pass/fail) the written exam and submit the final grade to the Program Director. Each student who passes the written exams will be able to begin preparation for the dissertation proposal oral defense.  

Oral Defense 

Following completion of the written qualifying exam and the written dissertation proposal, students will present their proposal in an oral examination. The oral examination may include questions that cover the student's focus area, directed reading and dissertation proposal. The examination will include a detailed review and discussion of the proposed dissertation research. Below is a list of the possible outcomes for each of the comprehensive exams:

Pass- You receive the affirmative votes of the majority of the members of your committee in order to pass.   

Pass with conditions- The committee may feel that although you have passed the examination you should complete additional work on your exams. These conditions will be specified and must be satisfied within 4 months of the defense.   

Fail- If you fail the examination, you may be subject to immediate dismissal from the program. At the program's discretion, you may be allowed to retake the examination once. The retake will be in a format designated by the committee and must be completed within 6 months.  

Final Dissertation Defense

A final examination of the dissertation will be conducted orally by the examination committee. Arrangements for the final examination must be sent to the DrPH education coordinator at least two weeks in advance. Below is a list of the possible outcomes for the defense:   

Pass- Affirmative votes by a the majority of the committee members signifying that the candidate has met the dissertation requirement. The committee may still request changes to the dissertation document but these should be minimal.   

Pass with conditions- A majority of committee members agree that the candidate will pass the dissertation requirement with additional work on the thesis that can be completed within a set timeline. These conditions will be specified and must be satisfied within 60 days of the defense.   

Fail- If a student fails the examination, s/he may not continue in the program.   

Timetable for Completion

The DrPH degree is designed to be completed within 4 years at full-time effort. Upon entering the DrPH program, students will have 3 years to pass the written qualifying exam and should complete the dissertation and public defense of the dissertation within 7 years of entering the program.
