Thank you for your interest in the Graduate Degree Program in Ecology (GDPE).

We offer three degree programs:

  • a research/thesis based Master of Science (MS) in Ecology
  • a PhD in Ecology
  • a PhD with specialization in Human-Environment Interactions 

See Curriculum & Courses under Current Students or the CSU Catalog for details. Funding is available through faculty advisors and teaching assistantships. 

If you are a currently enrolled graduate student at CSU and are interested in transferring into GDPE, please see the details at the bottom of this page.


Before You Apply

  1. You must have a GDPE faculty advisor to enter the program, so the first step is to identify those who share your research interests.
  2. Contact these faculty members to express your interest in joining their lab and having them potentially serve as your advisor (here’s a helpful article on how to do this).
  3. Most students admitted to the program are paid salary through their advisors, with research or teaching assistantships, and typically tuition is covered.
  4. Apply here.


Preferred Application Deadlines

To start in Fall: December 1
