Dr. Zellner received her Doctorate from the University of Toledo in 2012 where she trained in molecular and cellular biology, focusing on the role of silicon in plant defense responses.  Upon graduation, she pursued a four-year postdoctoral position with the USDA-ARS, where she continued studying the role of silicon in alleviating both abiotic and biotic stress in tomato and tobacco.  Her current studies are to design standard methods for quantifying the uptake of silicon from fertilizer material in addition to identifying uptake mechanisms for silicon in model species and testing for similar pathways in other crops.
