PhD and MS positions in Ecosystem Ecology are available in the Center for Ecosystem Science and Society (Ecoss) at Northern Arizona University.

The Ecoss mission is to conduct high-impact, innovative research on ecosystems and how they respond to and shape environmental change, to train next-gen scientists, and to communicate discovery and its relevance to people.

Graduate student benefits include stipend (TA or RA), tuition waiver, and health insurance.

Candidates should explore the Ecoss website ( and contact the professor whose interests align most closely.

Prospective students should directly communicate with an Ecoss faculty member before submitting an application. Although applications are officially due in the Department of Biological Sciences by January 15, 2022, we encourage applicants to submit prior to December 1, 2021 for possible consideration for a prestigious NAU Presidential Fellowship. When contacting an Ecoss faculty member, please include a description of your background, research interests and qualifications, as well as a current resume or curriculum vitae. Please consult the list of faculty to determine who is accepting new students for the 2022-23 academic year.

Ecoss is committed to fostering a diverse and inclusive workplace ( We strongly encourage applications from women and members of underrepresented minority groups.
