I am an associate professor at the University of Arizona in Tucson, Arizona.
I developed these course materials while teaching a Natural Science class (BE170A2) an innumerable number of times during the last 25 years. I add materials each year, as time allows.
My research interests are modeling algae growth in commercial algae production ponds, and modeling irrigation of guayule and guar, which are industrial crops. The picture above shows our current SBAR (Sustainable Bioeconomy for Arid Regions, USDA-NIFA) guayule deficit irrigation experiment at the Maricopa Agricultural Center near Phoenix, Arizona. Guayule is a native desert plant that produces rubber, resin, and biomass. The goal of the experiments and models is to use as little water as possible while maintaining agricultural productivity in our increasingly water stressed region.
