This page describes the thesis option offered on our main campus at Stillwater.  Students who plan to work in industry, consulting, or with regulatory agencies (such as EPA, ODEQ, etc.) may consider the Professional Science Master's (PSM) program offered at our satellite campus in Tulsa.

The Master of Science degree requires students to complete a 36 credit hour course of study. Students must also complete a program assessment form upon completion of degree and return it to the program coordinator.

MS students must complete one of the following research options. All options must have an oral or written presentation of a research proposal and an oral defense of the final product. The ESGP program is an interdisciplinary program, and thus the students’ research efforts are expected to address an environmental problem from multiple perspectives, which may include a social and/or economic perspective.
