The GDPE curriculum is designed to balance providing the fundamentals of ecology that unite students in our program with allowing customization for each student’s individualized scholarly pursuits. There are four courses required of all MS and PhD students: Foundations of Ecology (ECOL 505), Distinguished Ecologists Lecture Series (ECOL 571), Interdisciplinary Seminars in Ecology (ECOL 592), and Research Seminar (ECOL 693). These required courses provide the common foundation for all GDPE students and ensure that all students engage in key intellectual opportunities within the program. The many different electives available allow students to specialize and customize their individual MS or PhD degree.

Previously completed Master’s
Please refer to the Graduate School’s website for current details on credits that apply from a previously earned Master’s degree.
- MS in Ecology with GDPE: Students may apply courses taken during their MS toward fulfilling the PhD course requirements with the exception of ECOL571 and ECOL592. These must be retaken.
- MS from CSU: If students transition immediately from a MS to a PhD, they may apply all of their MS credits toward fulfilling the Graduate School’s 72-credit requirement. If there is one semester or more in between degree plans, students can apply up to 30 credits from their MS to their PhD credit requirements.
- MS from another Institution:
- University credit requirements: 30 credits may be applied toward fulfilling the Graduate School’s 72-credit requirement. These will be applied as a single lump sum when the Program of Study is submitted during a student’s 3rd semester. Refer to the Graduate School’s website for details.
- GDPE course requirements: Students may request to have specific course requirements waived if they have taken analogous, graduate-level, courses during their MS. More details can be found on the GDPE Course Substitution Petition. Note that students are still responsible for fulfilling university credit requirements.
