Prospective Students

Master Of Science

The normal duration of the M.S. program in Geosciences is two academic years, and a minimum of 30 semester credits must be completed. A thesis describing the results of an original research project is required for the Plan A Master’s degree. The thesis is defended in an oral presentation and examination.

Doctor Of Philosophy

The Department of Geosciences offers a Ph.D. program in Geosciences (GEOS-PHD). Prospective Ph.D. students should visit the Geosciences website to identify likely advisors and contact them directly for further information about Ph.D. opportunities.

The Ph.D. program ordinarily takes three or more years beyond the M.S. degree. Candidates must complete a total of 72 semester credits beyond the B.S. degree. A master’s degree from an accredited college or university may be accepted for a maximum of 30 credits. Candidates are typically expected to assist in at least one semester of teaching. Written and oral qualifying exams are normally taken by the end of the second year, with successful completion advancing the student to Ph.D. candidacy. An original research project must be presented as a dissertation and defended in an oral exam.
