Szczepaniec earned her B.S. in Cell Molecular Biology and Genetics and Ph.D. in Entomology from University of Maryland, College Park. Current work is focused on sustainable approaches to management of pests associated with industrial hemp including establishing economic injury levels in conventional and organic hemp production, incorporating biological control in IPM of hemp and specialty crops, insecticide resistance, and mechanisms driving irruptive pest population dynamics.
