Last Date to Apply
*Applications are reviewed on a rolling-basis and this posting could close before the deadline. ARS Office/Lab and Location: A postdoctoral research opportunity is available with the US Department of Agriculture (USDA), Agricultural Research Service (ARS), Delta Water Management Research Unit located in Jonesboro, Arkansas. The Agricultural Research Service (ARS) is the U.S. Department of Agriculture's chief scientific in-house research agency with a mission to find solutions to agricultural problems that affect Americans every day from field to table. ARS will deliver cutting-edge, scientific tools and innovative solutions for American farmers, producers, industry, and communities to support the nourishment and well-being of all people; sustain our nation’s agroecosystems and natural resources; and ensure the economic competitiveness and excellence of our agriculture. The vision the agency is to provide global leadership in agricultural discoveries through scientific excellence. Research Project: Research projects will be conducted in irrigated agricultural fields in the Lower Mississippi River Basin. The project will investigate the impacts of innovative water and crop management practices on greenhouse gas emissions, yield, and grain quality. The project will use but is not limited to the eddy covariance method to quantify greenhouse gas emissions from fields. The project will also improve the methodology of post-processing algorithms and data analysis. Under the guidance of a mentor, the participant will be involved in the following activities: - Conduct field measurements and analyses of GHG fluxes, analyze experimental data using advanced statistical procedures, systematically manage meteorological and eddy covariance data, and able to oversee maintenance of multiple eddy covariance systems - Actively engage with members of an interdisciplinary scientific research group - Write peer-review scientific journals articles, summary of progress report and present findings at conferences or scientific meetings. Learning Objectives: Under the guidance of a mentor, the participant will increase her/his knowledge of agricultural greenhouse gas emissions, including measurements, post-processing data, and modeling. The research participant will have the opportunity to collaborate with USDA-ARS and collaborating university scientists, and scientists from state and federal agencies in researching and evaluating the impact management has on mitigating agricultural greenhouse gas emissions. Also, this opportunity will provide the participant with exposure to technical and policy issues surrounding climate smart agriculture. Mentor(s): The mentors for this opportunity are Chris Delhom ( and Dr. Michele Reba ( If you have questions about the nature of the research please contact the mentor(s). Anticipated Appointment Start Date: Winter 2022. Start date is flexible and will depend on a variety of factors. Appointment Length: The appointment will initially be for one year, but may be renewed upon recommendation of ARS and is contingent on the availability of funds.
