USDA-ARS Image Soil Health Analysis Postdoctoral Fellowship

ARS Office/Lab and

Location:

A research opportunity is currently available with the U.S. Department of Agriculture (USDA), Agricultural Research Service (ARS), located in Corvallis, Oregon.

This fellowship will require at least monthly travel to Washington, California, and/or Illinois to collect data.

Data collection facilities include synchrotron light sources in CA and IL, and vineyards in OR and WA.

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.

You will use a variety of sensor technologies including x-ray computed tomography, rgbd cameras, hyperspectral cameras, etc. mounted on a variety of imaging platforms to investigate the effects of soil health management practices on soil health metrics, crop yield, and quality under the guidance of a mentor at the Horticultural Crop Production and Genetic Improvement Research Unit in Corvallis, OR.You will collaborate with researchers to enable data collection (x-ray instruments, imaging boxes, robot mounted cameras, etc.)

and high throughput image data analysis from a variety of imaging modalities in the Python programing language. Processes for high throughput image data analysis will be developed on a variety of platforms including Department of Energy and Department of Agriculture computing clusters, local computing systems, and edge computing systems. You will collaboratively generate manuscripts for peer-reviewed publication based on the results of these processes.

Under the guidance of a mentor, you will:

• Learn to use advanced sensor and imaging technologies—including X-ray computed tomography, RGB-D cameras, and hyperspectral cameras to study agricultural systems.
• Gain experience evaluating how soil-health management practices affect soil-health indicators, crop yield, and crop quality.
• Develop skills in collecting image data using X-ray instruments, imaging boxes, robot-mounted cameras, and other field or laboratory imaging platforms.
• Help build high-throughput image-processing and analysis workflows in Python across multiple imaging modalities.
• Learn to develop scalable computational pipelines for local systems, edge-computing devices, and Department of Energy and Department of Agriculture computing clusters.
• Gain experience collaborating with crop-production, genetics, engineering, and data-science researchers.
• Strengthen scientific writing and communication skills through collaborative development of peer-reviewed research manuscripts.

The mentor for this opportunity is Devin Rippner (devin.rippner). If you have questions about the nature of the research, please contact the mentor(s).

January 4, 2027. Start date is flexible and will depend on a variety of factors.

The appointment will initially be for one year, but may be renewed upon recommendation of ARS and is contingent on the availability of funds.

The appointment is full time.

This opportunity is available to U.S. citizens only.

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.
