The Pennsylvania State University’s Department of Plant Science is seeking a Postdoctoral Researcher to evaluate the effects of projected climate change on northeastern U.S. dairy crop production systems and their nitrogen dynamics, as well as dairy cropping strategies to adapt to and mitigate climate change. The incumbent will work with multiple years of dairy cropping system field data to evaluate and refine the Integrated Farm System Model in simulating nitrogen dynamics in dairy cropping systems under various management practices and system responses to projected climate change. The incumbent will also evaluate dairy cropping system and nutrient management strategies to adapt to and mitigate projected climate change, while protecting air and water quality. The incumbent will work with an interdisciplinary team of Penn State and USDA-ARS scientists studying sustainable dairy forage and feed production systems at University Park, PA. This is a fixed-term appointment funded for one year from date of hire with excellent possibility of re-funding.For a description of the field cropping systems project, see: http://plantscience.psu.edu/research/areas/crop-ecology-and-management/cropping-systems For a description of the Integrated Farm System Model see: http://www.ars.usda.gov/Main/docs.htm?docid=8519 Applicants must have completed a Ph.D. in Agronomy, Agricultural (Biological) Engineering or a related scientific field with experience in dairy cropping systems research and modeling of agricultural production systems. The incumbent must be able to plan, develop, and implement research procedures; interpret results; and prepare scientific reports and articles for refereed publication. Applicants must submit a cover letter, C.V., transcripts, a statement of research interests, and list of references. Applicant materials will start to be reviewed on July 31, 2017 and continue until the position is filled.
