Dr. Jose Rafael Guarin is a postdoctoral research scientist at the Center for Climate Systems Research at Columbia University and the NASA Goddard Institute of Space Studies (GISS). His research discipline is in crop modeling, with a focus of using crop models to simulate interactions of extreme weather events and abiotic stresses on crop development for improved agricultural decision making. He is currently working on incorporating the responses of ozone stress and diffuse radiation into the pDSSAT and LPJml models for improved global agricultural modeling. His expertise is in both the technical aspects of the crop models and the scientific aspects of the agrometeorological interactions within the project. His previous research projects focused on the improvement of sustainable wheat cultivation and global food security in collaboration with the Agricultural Model Intercomparison and Improvement Project (AgMIP), the International Maize and Wheat Improvement Center (CIMMYT), the International Wheat Yield Partnership (IWYP), the NASA AECOM Air Revitalization Lab, and the Princeton Environmental Institute. He received his Doctor of Philosophy in Agricultural and Biological Engineering from the University of Florida in 2018.
