Stable Isotope Lab Manager Jobs (NOW HIRING)

Postdoctoral Scholar

Northern Arizona University (NAU) invites applications for a Postdoctoral Scholar in ecosystem ecology, biogeochemistry, or a closely related field to work on a newly funded, multi-year research project examining the impacts of wildfire and fuel treatments on carbon dynamics in black spruce forests of Interior Alaska. The position is based in Flagstaff, Arizona, with required summer fieldwork in Alaska each year.

The Postdoctoral Scholar will join a highly collaborative research team within the Center for Ecosystem Science and Society (ECOSS) at NAU and will work closely with Dr. Michelle Mack, Dr. Xanthe Walker, and Dr. Ted Schuur. The project integrates field-based measurements, soil biogeochemistry, radiocarbon dating, and quantitative modeling to estimate soil carbon turnover, fluxes, and long-term stability following wildfire and fuel treatments. The Postdoctoral Scholar will play a central role in designing and conducting field research, analyzing and synthesizing complex datasets, and leading peer-reviewed publications.

This is a full-time postdoctoral appointment for 3–4 years, contingent on performance and continued funding, with an anticipated start date in May 2026.

Responsibilities:

• 65% - Research and Publications
• Lead and contribute to field-based research in Interior Alaska, including soil sampling, site re-measurement, and experimental implementation of fuel breaks.
• Analyze and synthesize ecological, biogeochemical, and isotopic datasets to quantify changes in soil carbon pools and turnover.
• Apply radiocarbon (14C) and isotope-based approaches to estimate soil carbon age, turnover, and fluxes.
• Develop and apply statistical models.
• Lead and co-author peer-reviewed publications and present results at scientific conferences and stakeholder workshops.
• Participate in lab meetings, project meetings, and interdisciplinary scientific discussions.

• 20% - Data Management and Analysis
• Curate, manage, and analyze large, multi-source datasets.
• Develop reproducible analysis workflows using R or similar programming languages and document code using version control (e.g., GitHub).
• Produce publication-quality figures and data products.

• 5% - Grant and Project Support
• Assist with project coordination, reporting requirements, and collaboration with federal and state partners as needed.

• 5% - Academic and Lab Citizenship
• Contribute to a collaborative, inclusive, and respectful research environment.
• Assist with general lab activities related to project goals.

• 5% - Other
• Other duties as assigned.

Minimum Qualifications:

• PhD in Ecology, Soil Science, Environmental Science, Forestry, Earth Science, or a closely related discipline by the start date.
• *A combination of related education, experience, and training may be used as an equivalent to the above Minimum Qualifications.

Preferred Qualifications:

• Experience with wildfire ecology.
• Experience with radiocarbon (14C) or stable isotope analyses.
• Laboratory and field experience collecting, processing, and analyzing soil and vegetation samples.
• Record of peer-reviewed scientific publications.
• Experience working in collaborative, interdisciplinary research teams.
• Demonstrated experience with quantitative data analysis (e.g., R or similar programming languages).
