The admissions committee and the department chair will evaluate the credentials of each applicant for the PhD program, considering a broad range of criteria, including:

  1. Content of the undergraduate program and, if applicable, graduate programs and grades earned, particularly in the areas of Geosciences, Mathematics, Physics, and Chemistry.
  2. A cumulative GPA of 3.0 or better in the last 60 hours of course work
  3. Letters of recommendation from three (3) individuals (preferably faculty members), who are able to judge the candidate’s academic abilities and potential for scholarly research.
  4. GRE scores, if submitted (see above).
  5. English proficiency test scores, when applicable.
  6. Scientific, professional, technical publications, and Master’s Thesis (if applicable).

In addition to these requirements, graduate admission may also be contingent upon a faculty advisor agreeing to supervise the applicant.  Therefore, prospective students are strongly encouraged to contact faculty members in the applicant’s field of interest prior to the application deadline.


Candidates in the Geophysics PhD program must demonstrate general proficiency in mathematics, physics, and geology. Some graduate courses explicitly require prerequisite courses.

The department will determine what deficiencies -if any - are present, and the acceptable means of removing those deficiencies (e.g. course work within and/or outside the department, directed study, research papers). Waivers of requirements will be considered on an individual basis. Applicants with a few deficiencies can satisfy those requirements while also taking graduate courses at the University of Houston.

Academic Policies

Scholastic Requirement

  • Graduate students must maintain a minimum grade point average of 3.00 in all course work to be considered in good standing.
    • Students not in good standing cannot receive a graduate degree and can be declared ineligible for support with a graduate assistantship (IA, TA, RA/TE or RA).
  • Graduate students who receive grades of C+ or lower in 12 or more semester hours of course work attempted for graduate credit are ineligible for any advanced degree at this institution.
  • Semester hours of “U” grades in S/U-graded courses apply toward the above 12-hour total.

Research (Dissertation) Advisor/Research Committee

Ph.D. applicants are encouraged to formulate their dissertation committee promptly in order to ensure proper guidance throughout their research.

  • Committee Composition
    • Doctoral students’ dissertation committees must be comprised of:
      • a minimum of four members to include three faculty members who have their primary appointment within EAS
      • one approved member external to the major department from industry or academia who is acceptable to the department and approved by the college.
    • A faculty member with a joint appointment in EAS is considered as an outside member unless he/she chairs the committee. In this case, an additional external member outside the major department is required.
    • After these minimum requirements for committee members are satisfied, additional committee members may be approved from industry or academia, but at least 50% of the committee must be tenured/tenure‐track faculty at the University of Houston.
    • Research faculty or instructional faculty may serve on dissertation committees, but not chair the committees. However, a research professor may serve as a co‐advisor with a tenured/ tenure‐track faculty.
  • Candidates must specify a dissertation committee and have the names on file in the NSM Office of Academic Affairs at least one semester prior to their graduation.


To become a candidate for the doctoral degree a student must meet a set of requirements established by the EAS Department. For all EAS doctoral aspirants, there are two options available to attain candidacy. It is the responsibility of the dissertation advisor to notify the department academic advisor and applicable graduate advisor which path to candidacy the graduate student will undertake by the end of the term preceding the candidacy exam or paper submission (Candidacy Options 1 and 2, respectively. See below).

  1. Candidacy Option 1 - Qualifying Exam and Proposal:
    • A five-member examining committee will administer a written exam, approximately 4 hours in length, given during the seventh to eighth week of each term.
      • It will test the breadth of the candidate’s knowledge within their discipline.
    • Approval by a majority of the members of the examining committee is required for the student to pass the examination.
      • At the discretion of the examining committee, a student who fails the general examination can be permitted to re‐take it; however, the exam cannot be taken more than twice by the applicant.
      • Re‐examination will take place within one (1) month of the initial examination.
    • The student must pass the candidacy examination before proceeding to the dissertation proposal.
    • All candidacy and proposal requirements must be completed by the end of the 4th term in the program.
  2. Candidacy Option 2 - Manuscript Submission and Proposal:
