David G. Mendoza-Cózatl is an Associate Professor of Plant Stress Biology at the University of Missouri, Columbia, USA. He received his PhD in Biochemistry from the Universidad Nacional Autónoma de Mexico and completed a PEW postdoctoral fellowship at UC San Diego. His research focuses on understanding how plants acquire nutrients from the environment and allocate them throughout the plant, and this includes nutrient sensing and the molecular mechanisms behind plant adaptation to changing levels of nutrients. Understanding these mechanisms is critical to achieving food security and sustainable agriculture.
