Umair Gull is a Ph.D. candidate in Department of Plant Sciences, University of California-Davis. His research focuses on quantifying alfalfa (Medicago sativa L.) yield, quality and water productivity under stressed and non-stressed conditions. He’s also trying to assess the spatio-temporal variability in alfalfa fields using the modeling and remote sensing approaches. Prior his joining as a Ph.D. student here at UC Davis, he completed his B.Sc. (Hons.) in Agriculture-Agronomy and M.Sc. (Hons.) Agriculture-Agronomy from University of Agriculture, Faisalabad, Pakistan (UAF-Pak). During his master’s research program, he worked on simulating wheat yield under different irrigation regimes using Agricultural Production Systems Simulator (APSIM) model. He also worked with Decision Support System for Agrotechnology Transfer (DSSAT) model for simulating responses of rice-wheat and cotton-wheat cropping system under changing climate in internationally funded projects like Agricultural Model Intercomparison and Improvement Project (AgMIP) and DFAT-CSIRO project at UAF-Pak.
