What are the responsibilities and job description for the USDA-ARS Postdoctoral Fellowship to Study Maize Genetic Resources position at U.S. Department of Agriculture (USDA)?
*Applications are reviewed on a rolling-basis.
ARS Office/Lab and Location: A research opportunity is currently available with the U.S. Department of Agriculture (USDA), Agricultural Research Service (ARS), Plant Introduction Research Unit (PIRU), located in Ames, Iowa.
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 of the agency is to provide global leadership in agricultural discoveries through scientific excellence.
Research Project: Under the guidance of a mentor, you will engage in research aimed at improving seed regeneration methodology, phenotypic, and genotypic characterization of the USDA maize germplasm collection. Systematic and thorough genotypic and phenotypic characterization would improve collection utility and aid in facilitating the research needs of seed requestors. During the fellowship, you will collaborate with Iowa State University maize breeders and geneticists, PIRU unit members and established USDA ARS/academic/industry collaborators while conducting research. The maize collection will be regenerated in the field and greenhouse in Ames, Iowa, and other off-site nurseries as needed and resources allow. Genotyping activities will be outsourced, and data receipt and initial quality assessment will be coordinated with the genotyping service institution. You will receive sequence/genotype data, help conduct analyses to survey variation, calculate relationships, and other relevant analyses of genebank accessions. You will interact with collaborators to upload genotypic and phenotypic data directly into the GRIN-Global database or to link all data via an external public platform for access.
Learning Objectives: Under the guidance of a mentor, you will have the opportunity to learn to:
- Conduct research efforts to measure, analyze, and use the genetic diversity in the USDA National Plant Germplasm System maize collection,
- Discuss all genetic resource management activities,
- Describe regeneration and phenotyping approaches in greenhouse and field experiments,
- Describe approaches used for marker traits associations in crop plants, and;
- Demonstrate communication (writing, presenting, etc.), collaboration and in conducting scientific research.
Mentor(s): The mentor for this opportunity is Adam Mahan (adam.mahan@usda.gov). If you have questions about the nature of the research, please contact the mentor(s).
Anticipated Appointment Start Date: November 2026. 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.
Level of Participation: The appointment is full time.
Citizenship Requirements: This opportunity is available to U.S. citizens only.
ORISE Information: This program, administered by ORAU through its contract with the U.S. Department of Energy (DOE) to manage the Oak Ridge Institute for Science and Education (ORISE), was established through an interagency agreement between DOE and ARS. Participants do not become employees of USDA, ARS, DOE or the program administrator, and there are no employment-related benefits. Proof of health insurance is required for participation in this program. Health insurance can be obtained through ORISE.
