Postdoctoral Research Associate in Aquatic Biogeochemistry

Expiration Date: 


The Biodiversity and Ecosystem Health Group within the Environmental Sciences Division at Oak Ridge National Laboratory is seeking a Postdoctoral Research Associate to contribute to an exciting new project quantifying greenhouse gas (GHG) emissions from hydropower reservoirs. In this position, the researcher will work on the development and validation of novel, in-situ GHG measurement technologies and will design and execute field campaigns that will employ multiple techniques to measure GHG concentrations and emissions within and among hydropower reservoirs. The researcher will work closely with our interdisciplinary team of empiricists and modelers on this DOE-funded project.

Major Duties/Responsibilities:

  • Organize field campaigns and design sampling strategies to measure GHG concentrations and emissions from hydropower reservoirs within the southeastern US and potentially in other regions of the United States.
  • Contribute to the development and testing of novel GHG measurement technologies.
  • Analyze data using appropriate statistical and visualization techniques.
  • Present findings at national/international scientific conferences.
  • Publish results in peer-reviewed journals in a timely manner.
  • Work as part of an interdisciplinary team of scientists.
  • Interface directly with internal and external partners and stakeholders.
  • Ensure compliance with environment, safety, health, and quality program requirements.
  • Maintain a strong commitment to the implementation and perpetuation of values and ethics.

Basic Qualifications:

  • A Ph.D. in ecology, biogeochemistry, freshwater biology, environmental engineering, environmental sciences, or a related field is required.
  • Prior experience conducting fieldwork in freshwater ecosystems (reservoirs, lakes, streams, rivers).
  • Expertise in biogeochemistry, as measured through first-author publications and/or major conference presentations.
  • Applicants cannot have received the most recent degree more than five years prior to the date of application and must complete all degree requirements before starting their appointment.

Preferred Qualifications:

  • Experience measuring CH4 and CO2 dynamics in freshwater ecosystems.
  • Experience working with environmental sensors.
  • Experience with experimental design and statistical analyses, including analyzing multivariate and time series data.
  • A strong publication record and a desire to publish research in a timely manner.
  • Ability to work independently and also collaboratively as part of an interdisciplinary research team.

Other Information:

This is expected to be a 24-month appointment with the possibility of an extension of up to 12 months contingent on successful performance and availability of funding.

Applications should include a cover letter, current CV, and a list of at least three references.
