Research Associate in Geochemistry

Date: Aug 18, 2023

Location: Oak Ridge, TN, US, 37830

Company: Oak Ridge National Laboratory

Requisition Id 11442 

Overview: 

As a U.S. Department of Energy (DOE) Office of Science national laboratory, ORNL has an extraordinary 80-year history of solving the nation’s biggest problems. We have a dedicated and creative staff of over 6,000 people! Our vision for diversity, equity, inclusion, and accessibility (DEIA) is to cultivate an environment and practices that foster diversity in ideas and in the people across the organization, as well as to ensure ORNL is recognized as a workplace of choice. These elements are critical for enabling the execution of ORNL’s broader mission to accelerate scientific discoveries and their translation into energy, environment, and security solutions for the nation.

 

The Plant-Soil Interactions Group within the Environmental Sciences Division (ESD), Biological and Environmental Systems Sciences Directorate (BESSD) at Oak Ridge National Laboratory (ORNL) seeks a postdoctoral researcher with expertise in environmental (bio)geochemistry. This researcher will use a suite of analytical and spectroscopic tools to understand biogeochemical processes in terrestrial and aquatic ecosystems, with a particular emphasis on how interactions between nutrients and soil minerals such as metal oxides vary across redox and salinity gradients.

 

ORNL’s Environmental Sciences Division is an interdisciplinary research and development organization with more than 60 years of achievement in local, regional, national, and international environmental research. Our vision is to expand scientific knowledge and develop innovative strategies and technologies that will strengthen the nation’s leadership in creating solutions to help sustain the Earth’s natural resources. Our scientists conduct research, develop technology, and perform analyses to understand and assess responses of environmental systems at the environment-human interface and the consequences of alternative energy and environmental strategies.

 

Major Duties/Responsibilities: 

The candidate will directly support the project “Biogeochemical controls on phosphorus cycling in urban-influenced coastal ecosystems” funded by the DOE Early Career Research Program. The objective of this research is to evaluate how coastal biogeochemistry is shaped by large-scale water diversions along the Louisiana Gulf Coast.

 

The specific aims of this research are to (1) evaluate how soil moisture, redox potential, and salinity vary spatially and in response to seasonal and episodic disturbances; (2) examine how a suite of biogeochemical solutes that include phosphorus are mobilized into soil solution across redox and salinity gradients; (3) quantify inorganic and organic phosphorus reservoirs within wetland soils across different seasons; and (4) explore how mobilization of soil phosphorus responds to experimental redox and salinity manipulations.

 

Findings from this research will inform process-based models being developed to simulate biogeochemical reactions in coastal systems and will be particularly beneficial to expanding modeling capabilities within the E3SM Land Model (ELM).

 

The selected candidate will have the responsibility of:

  • Interacting with world-leading biogeochemical modelers and experimental and field researchers through the Critical Interfaces Science Focus Area and Next Generation Ecosystem Experiments (NGEE) Arctic programs.
  • Collaboratively leading field and laboratory studies to investigate metal and nutrient interactions in soil.
  • Have access to a broad suite of analytical and spectroscopic equipment, including a laboratory-based x-ray absorption spectroscopy system.
  • Maintaining detailed scientific records, analyzing experimental data, presenting results within the research group and at national and international conferences, and preparing manuscripts for publication in peer-reviewed journals.
  • Maintaining a safe work environment in compliance with safety guidelines.
  • Promoting a constructive and respectful work environment.
  • Deliver ORNL’s mission by aligning behaviors, priorities, and interactions with our core values of Impact, Integrity, Teamwork, Safety, and Service. Promote diversity, equity, inclusion, and accessibility by fostering a respectful workplace – in how we treat one another, work together, and measure success.

 

Basic Qualifications:

  • A PhD in Geosciences, Earth and Environmental Sciences, or a related field with a strong focus on terrestrial biogeochemistry, completed within the last 5 years
  • A strong record of independent and productive research, as indicated by conference presentations and/or publications in peer-reviewed journals.
  • Ability to work independently and collaboratively as part of a large multidisciplinary team, and should be able to design and execute experiments, perform data analyses, and interpret experimental results.
  • Excellent interpersonal, oral, and written communication skills.

 

Preferred Qualifications:

  • Experience with application of spectroscopic and other analytical techniques to grand challenges in environmental research.
  • Demonstrated ability to independently operate analytical equipment.
  • Experience conducting field work independently or as part of a team.
