What will I learn?

The Ph.D. in Ecology and Environmental Sciences was developed jointly by the Departments of Ecology and Land Resources & Environmental Sciences as a broad interdisciplinary Ph.D. program open to graduate students in several departments in the Colleges of Letters & Science and Agriculture. The degree program was approved by the MUS Board of Regents in 2006, and now meets the interests of graduate students in Ecology in a broad array of subjects. Other participating departments include Animal and Range Sciences, Earth Sciences, Microbiology and Immunology, Plant Science and Plant Pathology, and the College of Nursing.

Because of the substantial diversity in disciplinary and multidisciplinary foci within the EES doctoral program, there is no universal required core curriculum. The student's individual coursework program will be developed in partnership with the major advisor and graduate committee usually following the Department of Ecology's required oral qualifying exam during the third semester in attendance. The plan must be consistent with all of the home department and the Graduate School guidelines and requirements. A minimum of 30 credits of resident coursework must be taken from MSU.
