The Department of Agricultural and Biological Engineering at the University of Florida has a world-renowned program on the development and application of dynamic crop simulation models. The department is also responsible for the Decision Support System for Agrotechnology Transfer (www.DSSAT.net), one of the most widely used crop models across the globe. A graduate research assistantship is available funded by the Boote Graduate Student Support program. We are looking for a highly motivated PhD candidate who is interested in conducting research toward the development, advancement, and application of the DSSAT crop simulation models, including supervised, field-based experiences related to the student’s area of study. Eligible students must demonstrate a strong academic interest in crop physiology and the application of the DSSAT crop model and must have earned at least a bachelor’s degree in agricultural engineering, agronomy, horticulture, soil science or related field from a land-grant institution. Strong written and verbal communications skills as well as programming experience are recommended. If you feel that you meet these qualifications, please send a one-paragraph statement to Gerrit Hoogenboom, Department of Agricultural and Biological Engineering, University of Florida (gerrit@ufl.edu).
