The EEOB Graduate Program offers graduate study leading to both M.S. and Ph.D. degrees.

As a member of the program, you will have a unique and diverse set of educational experiences, including: a broad background in evolution, ecology, and organismal biology; exposure to exciting and modern research; training in pedagogy and the opportunity to teach undergraduate laboratories and discussion sections; and immersion in your specific area of concentration. These experiences will serve you well while in graduate school and also prepare you for a successful career in biology.

The EEEOB Graduate Program has cooperating faculty from various disciplines.

Including Anthropology, Botany and Plant Sciences, Conservation Biology, Earth Sciences, Environmental Sciences, Entomology, Nematology, Microbiology and Plant Pathology, and Psychology. With over 40 faculty members available as mentors, you will have the opportunity to perform your research across a broad range of topics.

The EEOB Graduate Program offers both M.S. and Ph.D. degrees in Evolution, Ecology, and Organismal Biology.
Requirements and More Information:


  • The Ph.D. Program

    The Ph.D. degree requires demonstration of broad knowledge of Ecology, Evolutionary Biology, and/or Organismal Biology, and substantive ability and accomplishment in original research. Summary information about the specific requirements for successful completion of the degree is outlined below and more detailed information can be found by following the appropriate links below and in the EEOB Graduate Program Handbook.

  • Required Courses
    1. EEOB 400 (Introduction to Graduate Studies)
    2. One Foundational Course in Evolution (EEOB 216), Ecology (EEOB 211), or Organismal Biology (EEOB 210)
    3. One additional 4-unit graduate course from an approved list
  • Current Research Topics Courses
    1. BIOL 252 Seminars
    2. EEOB 265 Seminars

    (minimum of 12 quarters in each)

  • First-year Research Project

    To be presented in EEOB 265 in Fall quarter of student's second year Format as a "Contributed Presentation".

  • Written Qualifying Exam Evaluation

    Evaluated by a standing committee of EEOB faculty members with ad hoc review as necessary.

  • Oral Qualifying Exam

    Usually in the Fall quarter of the student's third year.

  • Teaching Requirement

    Minimum of three quarters as a Teaching Assistant.

  • Dissertation

    Final Defense and Written Dissertation are required.

  • Time to Completion

    Students are strongly encouraged to complete the requirements within five years. During the first two years, emphasis is on course work and reading as well as initial research in preparation for Written and Oral qualifying examinations. The final two or three years are devoted primarily to research and to the writing and defense of the Dissertation. There is no foreign language requirement for the Ph.D.

  • Qualifying Procedure

    Students meet with their guidance committee as soon as possible in their initial quarter of study. The guidance committee is assigned by the Graduate Advisor for Recruitment on the basis of your perceived interests indicated in your statement of purpose provided with your application. The committee works with you to design an appropriate academic course of study for your degree plan and helps you select an appropriate major professor.

    The Ph.D. qualifying procedure requires satisfactory completion of the written qualifying examination, preparation of a research proposal, and an oral qualifying examination. The written qualifying examination is a comprehensive examination in the field of specialization. It is normally taken in the student's sixth quarter of residence. The Oral Examination is conducted by the student's Qualifying Committee and may cover any material relevant to the interest and goals of the student, especially those in the student's area of research specialization. Work on the proposal and preliminary experiments may begin at any time but the final proposal should be submitted before the beginning of the third year. After successful completion of the Oral Examination, the student is advanced to candidacy for the Ph.D. and the Dissertation Committee is formally appointed.

  • The Dissertation

    The format of the dissertation is somewhat flexible (e.g., it may be a formally prepared 'stand-alone' document or a collection of autonomous research papers with appropriate introductory and summary sections), but must meet with the approval of the Graduate Division and the Dissertation Committee. It is the responsibility of this Committee to decide when data of sufficient quality and quantity have been gathered to demonstrate proficiency in independent research. The final Oral Examination includes a public formal presentation (seminar) on the dissertation research followed by a question period. Once the Committee is satisfied with the dissertation, and it is filed with the Graduate Division, all requirements for the Ph.D. will have been met.

    For more information please refer to the EEOB Graduate Program Handbook.

  • The Master of Science Program

    The UCR Department of Evolution, Ecology and Organismal Biology offers a Master's Degree based on research; we do not offer a coursework M.S. degree.

    Students accepted into the M.S. program should, in the first year, take basic course work in Ecology, Evolutionary Biology, or Organismal Biology and also plan and begin a research project. By the end of the second quarter, the student should select a faculty research sponsor and prepare a brief description of the proposed research. 

  • General Expectations and/or Requirements
    • Research should be initiated by the third quarter, and students should register for Biology 297, Directed Research.
    • Twenty-four units of course work in graduate courses (200 series) in biological sciences, of which at least 12 must be courses other than 290-299. The remaining 12 units can be taken either in the 100 or 200 series.
    • Enrollment is expected in Biology 252 seminar and the 265 "lunch bunch" for all students during the Fall, Winter, and Spring quarters.
    • It is generally advisable to concentrate on formal course work during the first year and on research in the second year.
    • Thesis preparation should begin no later than the beginning of Spring quarter in the student's second year.
    • Presentation of an acceptable thesis and final oral defense of theses are required of every candidate for the M.S. degree.
    • Please be aware, M.S. students are self-funded and are not eligible for financial support.
  • Progress Evaluation for M.S. and Ph.D.

    For both M.S. and Ph.D. students, evaluations of progress are carried out each year by the faculty of each specialization, or a committee thereof. All evaluations are reviewed by the Graduate Advisory Committee which is responsible for making specific recommendations to the Graduate Division concerning the student's progress. It is also the responsibility of the Graduate Advisory Committee to recommend exceptions to the normal time schedule occasioned by unusual circumstances. The student is notified in writing of the results of the annual evaluation and a copy is forwarded to the Graduate Division.
