Dr. John Jifon is an Associate Professor of Plant EcoPhysiology at the Weslaco AgriLife Research and Extension Center and Department of Horticultural Sciences. His research focus includes identifying key environmental limitations on productivity, elucidating the mechanisms that enable plants to cope with environmental stresses, and, developing physiological strategies to mitigate stress effects and increase production efficiency, quality and cropping system sustainability. Areas of current research concentration include (i) optimizing pre-harvest agronomic practices to improve the nutritional/health quality of food crops, (ii) exploring physiological strategies to improving on-farm water use efficiency, water productivity and water conservation, and (iii) evaluating a range of lignocellulosic feedstocks for adaptability and agronomic performance (water/nutrient use, yield, energy density) under semiarid subtropical conditions.
Dr. Jifon obtained his Ph.D. at Cornell University, Ithaca, NY, and his MS and BS degrees at Mississippi State University and The University of Edinburgh, U.K., respectively. Prior to joining TAMU, he worked at the University of Florida, Institute of Food and Agric. Sciences (IFAS), Citrus Research and Education Center, Lake Alfred FL as a PostDoctoral Research Associate, on radiation stress and elevated carbon dioxide concentration effects on citrus.
