She holds a Ph.D. from Virginia Tech with a focus on Agroecology and a dissertation on cover cropping’s role in high-functioning agroecosystems with field studies on fertilizer equivalence of strip-tilled corn production systems. Her master’s degree in Entomology and Nematology from the University of Florida focused on soil solarization as an alternative to soil fumigant and examined the effects on soil microarthropods, nematodes, and nutrient cycling. Her undergraduate degree was also from UF where she studied botany, ecology, and chemistry.
