Biology, Doctor of Philosophy

Department of Biological Sciences

College of Engineering, Forestry, and Natural Sciences

This doctoral degree allows advanced students to pursue their content and research skills while studying under faculty specialists in microbiology, botany, genetics, bioinformatics, human biology, ecology, and zoology. The program is enhanced by advanced research facilities that include the Deaver Herbarium, the Electron Microscope Facility, and the nationally prominent Microbial Genetic and Genomics Center, home to powerful research into anthrax, plague, and other bacterial-disease-causing infections.

  • To receive a Doctor of Philosophy Degree (PhD) at Northern Arizona University, you must complete a planned group of courses, from one or more disciplines, ranging from at least 60 - 109 units of graduate-level courses. Most plans require research, a dissertation, and comprehensive exams. All plans have residency requirements regarding time spent on the Flagstaff campus engaged in full-time study.

  • Please note that you may count only 15 units of dissertation credit toward your degree. However, experience tells us that our doctoral students in Biology end up taking an average of 36 units. This is due to the requirement that you register for BIO 799 for each semester during which you work on your dissertation.
