Research Associate (Post doc)

Agricultural Research Service, Fort Collins, CO, United States
Employer Description
Find Solutions to Agricultural Problems that Affect Americans Every Day, From Field to Table.
Job Description
The Agricultural Research Service (ARS) is the USDA's chief scientific research agency and one of the world's premiere scientific organizations. ARS Postdoctoral Research Associates are hired to supplement a lead scientist's research on agricultural problems affecting American agriculture. This position is with the Water Management & Systems Research Unit, Fort Collins CO. Desired start date May 2021. **ANNOUNCEMENT IS OPEN UNTIL FILLED OR 2/25/2022**
Job Requirements
The selected candidate will have the opportunity for involvement in field work with a diverse team to quantify a range of plant and soil mechanisms determining crop productivity under drought (e.g., hydraulic and photosynthetic functioning, root growth and activity) influenced by soil N and microbes, and will compile datasets for use in modeling. Processes underpinning the interactions between water stress and N will be evaluated using a process-based biophysical model, TREES. They will develop novel AI frameworks to use the highly dimensional multivariate soil biology, management, and environmental datasets compiled, and use multivariate AI methods for understanding controls of water-N interactions on plant productivity and evaluating the role of microbiomes in soil processes controlling plant available resources. They will also will further objectives of 1) identifying mechanisms underpinning interactions between water stress, N availability and crop physiological responses on crop productivity, and 2) examine shifts in soil microbial functional groups to identify those linked to N supply and crop performance under limited water. This position requires a recent (within the last 4 years) Ph.D in Plant Physiology, Soil or Soil Microbial Science, or Agronomy) or a related field of study that has equipped the applicant with the necessary knowledge, skills and abilities to perform the duties and responsibilities of the position. Applicants must meet basic Office of Personnel Management (OPM) Qualification Standard's requirements of the scientific discipline necessary to perform the duties and responsibilities of the position. Experience: A recent PhD in plant, soil or soil microbial science, or agronomy (within 4 years of start date) is required. A strong background in quantitative data analysis (potentially including experience with soil microbiome or eddy flux data), experience with or willingness to learn process-based modeling, knowledge of programming, and familiarity with C++, R, and Python are highly desirable. Education Requirements:

Plant Physiology (0435) series: a degree in botany or plant physiology; or a related scientific discipline that included at least 10 semester hours in plant physiology. Soil Science (0470) series: a degree in soil science or a closely related discipline that included 30 semester hours or equivalent in biological, physical, or earth science, with a minimum of 15 semester hours in such subjects as soil genesis, pedology, soil chemistry, soil physics, and soil fertility. Agronomy (0471) series:a degree in agronomy or related discipline of science that included at least 30 semester hours of course work in the basic plant sciences, including at least 15 semester hours in agronomic subjects, such as those dealing with plant breeding, crop production, and soil and crop management.
