Area(s) of Expertise

Joining the NC State University floriculture program in 2015, Dr. Bergmann continues his career in plant science research that has ranged from the basic (somatic embryogenesis in Aesculus) to the applied (use of Paulownia foliage for goat fodder) and from the laboratory bench (microprojectile-mediated gene transfer to Pinus cotyledons) to the whole-ecosystem level (biodiversity and productivity of sustainable agro-ecosystems). Ben’s current research focuses on postharvest challenges in cut flowers, especially in regard to Botrytis cinerea susceptibility and ethylene sensitivity. Since his arrival at NC State University, Ben has conducted postharvest research with cut roses, chrysanthemums, snapdragons, gerberas, and dahlias.
