Dr. Lexi Duscher is originally from Minnesota and has lived in Florida for the past 11 years. She obtained her bachelor's in Marine Science with a focus on marine sponge disease at Eckerd College in St. Petersburg, FL. Dr. Duscher then attended graduate school at the Space Life Sciences Lab in Merritt Island, FL through the University of Florida where she studied a beneficial squid symbiosis (Vibrio fischeri and Euprymna scolopes) and innate immunity in a space-like environment. Her first postdoc position at the Whitney Laboratory for Marine Bioscience was focused on the innate immune response in stem cell regeneration of a cnidarian model system, Hydractinia. Dr. Duscher now applies her molecular skills and techniques to study cellular agriculture in Dr. Ovissipours’s Lab at the Virginia Seafood AREC. In her free time, she enjoys being outside at the beach, fishing, camping, and hiking.

Ph.D., Microbiology and Cell Science, University of Florida, 2019

B.S., Marine Science, Eckerd College, 2013

B.A., Environmental Studies, Eckerd College, 2013

Dr. Lexi Duscher's research focuses on optimizing cost-effective and efficient fish cell culture for the development of cultivated seafood. My current and future research goals are focused in the following areas:

  • Development of serum-free fish cell culture media
  • Develop fish stem cell differentiation methods for muscle and fat cell production using food-grade materials
  • Structure living fish cells into cultivated meat fillets via plant-based scaffolding and 3D bioprinting
