The Biology program of the Northern Arizona University provides advanced training in research through focused coursework and extensive research experience, using an integrative, interdisciplinary, and evolutionary approach. Students will develop expertise in collecting, analyzing, interpreting, and presenting data at a level appropriate to the profession.


Purpose Statement

The Biology program of the Northern Arizona University prepares students for research-focused professions in the biological sciences, developing students’ expertise in the empirical foundations of their dissertation area, and collecting, analyzing, interpreting, and presenting data to push forward the forefront of knowledge in their biological field of study. Our faculty members conduct research in the many fields of biology, from the level of single molecules to whole ecosystems. From the first day of entry into our program, students work closely with their faculty mentor, selecting a course of study suited to their future goals and professional interests.  The program enables graduates to contribute to the forefront of knowledge in the scientific community, share their knowledge through teaching, or apply it in public service or industry.

Students pursuing the emphasis in Ecology, Evolution & Conservation Biology will integrate theoretical and empirical concepts in ecology and evolutionary biology to understand ecological patterns and the mediating processes that drive populations, communities and ecosystems.  Students will become familiar with ecological sampling techniques and statistical methodologies necessary to characterize populations, communities and ecosystems over broad geographic regions, and will apply current approaches for identifying and mitigating the effects of invasive species and anthropogenic impacts on threatened and endangered species within the natural ecosystems they inhabit.
