Ph.D. in Biology

Format: Campus

Program Description:

The PhD in Biology program is enhanced by NAU-Flagstaff's location in northern Arizona, where you’ll discover an environment conducive to both academic and personal development. The San Francisco Peaks (to 3,852m) tower above Flagstaff and NAU. The Colorado River traverses the Grand Canyon only 75 miles from Flagstaff. Vast networks of canyons and mesas, mountains and meadows, and lakes and ponds harbor a rich diversity of environments and organisms. Habitats ranging from alpine tundra to Sonoran Desert are readily available for field studies. In addition, lab-based projects use contemporary training in microbial, molecular, and cellular biology techniques, which complement studies directed at the organism and ecosystem levels. Our faculty in biology comprises specialists in the field and lab disciplines of botany, zoology, and microbiology. These Biology faculty members combine high-quality teaching programs with strong and productive research and participate with faculty from other departments in interdisciplinary programs. Our cordial and frequent faculty-student interactions foster an atmosphere of free exchange among scholars at all levels. You can request additional information about faculty research interests, degree programs, facilities, special programs, and support from our departmental office. We also encourage you to contact our faculty members directly for information about their research interests.
