Doctor of Philosophy in Environmental Health Sciences


UCLA Fielding School of Public Health

Environmental Health Sciences

The PhD in Environmental Health Sciences develops in-depth skills and knowledge that enable graduates to perform independent original research on contemporary environmental and occupational health challenges. Students work with their faculty advisor to identify an area of focus, and develop an appropriate training plan and research activities. Areas of academic focus can include, but are not limited to: aerosol science, air quality, climate change, exposure science, industrial hygiene, policy analysis, epidemiology, toxicology, or water quality.

  • Program Requirements

    The doctoral program encompasses the following major elements:

    • Course work in the major field
    • Written qualifying examinations, including proposals related to the dissertation
    • Oral Qualifying Examination on the proposal for the dissertation (advancement to candidacy)
    • Dissertation
    • Oral defense of the dissertation 

    1. Course Requirements

    Students select a course of study upon consultation with Guidance Committee. Proficiency in biostatistics/statistics is required. Each specific required course can be waived if the equivalent has been successfully taken previously with a grade of B or better.

    EHS required courses include:

    • EHS C200C: Foundations of Environmental Health Sciences
    • EHS 296: Research Topics in EHS required for each quarter in residence)
    • EHS 411: Environmental Health Sciences Seminar: Taken once a year for two years 
    • One full course (4 units or more at the 100 or 200 level) in Epidemiology 
    • Students who have not previously completed a CEPH-accredited degree (bachelor’s, master’s or doctoral degree) are required to complete Public Health 201: Contemporary Health Issues.
    • EHS 414A: Research Methods and Effective Communication
    • EHS 414B: Research Methods and Effective Communication 

    2. Written Doctoral Qualifying Exam

    The aim of the Written Doctoral Qualifying Examination is to verify that the candidate has state-of-the-art knowledge about the general areas of the major field (intended research and its relationships to environmental health sciences and to public health). The student must complete the minimum course requirements to the satisfaction of the Guidance Committee before taking the Examination.

    3. Oral Doctoral Qualifying Exam

    On successful completion of the written Qualifying Examination, the doctoral committee is named to administer the Oral Qualifying Examination. The exam focuses on the proposal for the dissertation. It also includes the following as appropriate: theory and background research relevant to the proposed research beyond that reviewed in the proposal; methodological and analytic considerations pertinent to the proposed research, irrespective of whether these issues have been covered in the proposal; and feasibility. The proposed research must make an original contribution to the field. 

    4. PhD Dissertation

    After passing the University Oral Qualifying Examination, students may be advanced to candidacy and commence work on a dissertation in the principal field of study. The doctoral committee supervises the progress toward completion of the dissertation.

    5. Final Oral Examination (Defense of Dissertation)

    A final oral examination is required of all candidates.

  • Time to Degree

    Normative time from initial enrollment to advancement to candidacy is six to nine quarters (two to three calendar years), and from advancement to candidacy to filing of dissertation is six to nine quarters (two to three calendar years).
