All GS grads receive a funding package of $41,208 (as of 7/1/22) per year, plus a tuition waiver and health insurance. Funding is typically provided by the department during your first year and by your lab thereafter.

Outside Funding:

All students should apply for outside funding. Your own fellowship will look great on a resume and will also make your thesis advisor very happy...

Specifically, the department expects all students who are US citizens or permanent residents to apply for National Science Foundation fellowships. You will take a course that will prepare you for this application. NSF funding opportunities can be found at: http://www.nsfgrfp.org/
