Job Description

How much disturbance can forests absorb before their carbon cycle can’t recover? Why? What mechanisms determine ecosystem resilience?

A postdoctoral position is available at the Joint Global Change Research Institute (JGCRI) of Pacific Northwest National Laboratory (PNNL), in ecosystem modeling, analysis, and data assimilation. The successful candidate will lead the modeling component of an NSF-funded project, to be conducted in collaboration with a team at Virginia Commonwealth University.

The successful candidate will be responsible and accountable for:

  • Working both independently and collaboratively with other team members at PNNL and VCU to conduct ecosystem- to regional-scale modeling using the Predictive Ecosystem Analyzer (PEcAn) framework.
  • Exploring data assimilation and sensitivity analysis techniques to guide fieldwork measurement priorities.
  • Supporting new model and PEcAn framework development and activities under the guidance of senior modeling scientists.
  • Contributing to a second project, using the simple global carbon/climate model Hector to examine climate change effects in high latitude ecosystems.
  • Leading data analysis, the writing of peer-review journal publications, and presentation of results at scientific conferences such as AGU.

This position will be based at PNNL’s Joint Global Change Research Institute in College Park, Maryland. We’re seeking integration between modeling and fieldwork that helps elucidate mechanisms supporting forest resilience, and there may be opportunities for light fieldwork and/or data collection, with travel to the University of Michigan Biological Station in Pellston, Michigan. Funding is available for a three-year period, contingent upon satisfactory progress in. The preferred start date is between January and June 2018.

Equal Employment Opportunity

PNNL is an Equal Opportunity/Affirmative Action Employer that is committed to hiring a diverse, talented workforce. EOE Disability/Vet/M/F/Sexual Orientation/Gender Identity. Staff at PNNL must be able to demonstrate the legal right to work in the United States.

Minimum Qualifications

Candidates must have received a PhD within the past five years (60 months) or within the next 8 months from an accredited college or university.

Preferred Qualifications

Strong written and oral communication skills are essential. Good computer coding and data-analysis skills are required, as is a demonstrated record of research products (peer-reviewed publications). Experience with one or more specific models in the PEcAn framework (see, an interest in open-source and reproducible science, and experience with Linux-based computing clusters are all useful but not required.

A Ph.D. in carbon cycling, ecology, biogeochemistry, or a comparable discipline is necessary before starting employment.
