Ted DeJong is emeritus professor at the University of California at Davis, and has been doing research on fruit trees for 40 years. He has published about 300 scientific papers, most of which are on some aspect of the functioning of fruit trees. See his webpage at https://dejong.ucdavis.edu/ Rich Marini, PhD is a Professor of Horticulture with Penn State University, specializing in tree and small fruit physiology, data analysis and fruit production systems. Carlos H. Crisosto is Director of the Fruit and Nut Research and Information Center, UC Davis. The focus of his research and extension program is the postharvest biology and technology of fruits, especially peaches, nectarines, plums, apricots, table grapes, figs, kiwifruits, olives, and persimmons, as well as pistachios, almonds and walnuts. The goal of his research program is to develop a better understanding of the orchard factors and postharvest factors that control fruit flavor and shelf life and to develop technology to overcome fruit industry problems. He applies genomic techniques to identify gene(s) responsible for fruit sensory attributes (both desirable and undesirable), and investigating physiological disorders such as chilling injury.
