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, health insurance, and payment of other student fees.

Candidates should explore the Ecoss website ( and contact a faculty member (prospective advisor) whose interests align most closely with those of the applicant.

Program applications should be submitted to the home department recommended by the prospective advisor (Biology, School of Informatics and Computer Sciences, or School of Forestry). Although hard deadlines vary in different home departments, Ecoss requires that applications be submitted by January 15, 2023. Applications submitted earlier (by December 2, 2022) may be considered for a prestigious NAU Presidential Fellowship. Please include a cover letter describing your background, research interests, and qualifications, as well as a current resumé or curriculum vitae.

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