USDA ARS/ Adjunct Professor
Research Specialty and Interests:
The two major interests of our group are the molecular and biochemical basis of potato disease resistance and the nutritional enhancement of potatoes, which are the 4th largest crop in the world and a staple food. Our interests including systemic acquired resistance and salicylic acid-mediate signaling, along with analysis of the role of plant small molecules in pathogen and pest interactions. For example, trying to identify compounds in potato root exudate that stimulate hatching of the potato cyst nematode. Historically, relatively little effort has been directed towards enhancing the nutritional value of any crop, but advances of the last decade greatly facilitate such a goal. We are using diverse approaches towards maximizing the nutritional values of potatoes, including metabolic engineering of the folate and phenolic pathways, LCMS profiling of tuber phytonutrients in diverse germplasm and working with potato breeders using genetic approaches.
