Doctoral Program Requirements
To obtain a Doctor of Philosophy (Ph.D.) in Earth System Science, students must fulfill the following requirements:
- Completion of course work (10 courses, including core courses)
- Six quarters in residence at UC Irvine
- Completion of the Comprehensive Examination, with recommendation to continue for the Ph.D.
- Completion of the teaching and seminar requirements
- Pass the Advancement to Candidacy Examination
- Presentation of an open research seminar
- Submission of an acceptable doctoral dissertation and formal defense
The master's degree is awarded only to students admitted to the Ph.D. program who have completed eight courses, met the three-quarter residency requirement, and completed the Comprehensive Examination.
Students must complete a minimum of 10 approved graduate-level courses, including the core curriculum (Earth System Science 202, 212, 224, 226, 228, 240, 266 and 298), with an average grade of B or better. All courses must be approved by the student’s advisor.
Academic Senate regulations specify a minimum period of residence of six quarters for Ph.D. candidates. Enrollment in a minimum of 12 units of graduate/upper-division course work per quarter is required. Registration in every regular academic session is necessary until all requirements for the degree have been completed, unless a formal Leave of Absence is granted by the Graduate Division. All Ph.D. requirements must be completed within 15 quarters in residence (five years), excluding summer quarters. Exceptions must be put to a vote of the Earth System Science faculty. The maximum time permitted is seven years.
Progress toward the degree and readiness to begin research is assessed by a comprehensive examination covering breadth, general knowledge, and the ability to integrate and use information covered in the core curriculum and other coursework. At the end of the Spring Quarter, the ESS Comprehensive Examination Committee administers the written and oral examinations. The oral comprehensive examination is offered after the written examination and provides an opportunity to clarify questions that arise from the student’s performance on the written examination.
Teaching and Seminar
Students are required to complete a teaching assistant training program and to have a minimum of two quarters of experience as a teaching assistant, provided opportunities are available. Students can enroll in Earth System Science 399 while serving as a teaching assistant..Students are also expected to participate in the Earth System Science seminar.
Advance to Ph.D. Candidacy
Following completion of the Comprehensive Examination, those students who receive a recommendation to continue Ph.D. work will pursue research on a potential dissertation topic and then take the Advancement to Candidacy Examination. This oral examination is given by a faculty committee, including extra-departmental faculty. The normative time for advancement for candidacy is two years.
After advancing to candidacy, students are expected to be fully involved in research toward writing their Ph.D. dissertation. Students should keep in steady contact/interaction with their Doctoral Committee. A dissertation based on original research and demonstrating critical judgment, intellectual synthesis, creativity, and clarity in written communication is required for the Ph.D. degree. The dissertation must summarize the results of original research performed by the student under the supervision of a faculty member of the Department. The dissertation will be evaluated by the Dissertation Committee, based on suitability for publication in a peer-reviewed journal of high editorial standards. The dissertation may be a compilation of published papers or manuscripts accepted for publication, so long as the candidate has produced a major proportion of the material independently The Dissertation Committee approves the format and content, which must meet University requirements for style, format, and appearance.
