PhD Admission Information

GradApp is now open for Fall 2023 applications!
NOTE: GRE scores are no longer required for the PhD application. Applicants may choose to submit scores and they will be reviewed if there is a deficiency in another area of the application (lower GPA, etc.).


PhD Application Deadline: December 15, 2022

Interviews for the Doctoral Program are conducted in January or February.

Two ways to apply:

1. Apply directly to the Physiological Sciences Program. Instructions are on this page.

2. Apply indirectly through the Arizona Biological Biomedical Sciences Program (ABBS). ABBS is an umbrella recruitment program that allows you to select course work from Physiological Sciences in addition to several other programs during your first year of PhD training. After the first year you select your PhD program from the 8 participating programs.

Applicants are also allowed to apply to both programs. Both applications are submitted via the GradApp website. 

Applicants interested in the MD/PhD should first apply to the UA College of Medicine Tucson MD/PhD program. After completing 2 years of medical school students may apply to join the Physiological Sciences PhD program.
