CIOPORA Trainee Program Graduates

Elisabeth Doody

Plant Sciences Graduate, University of California Davis

"Joining CIOPORA as a student trainee remains one of the most professionally and personally meaningful experiences of my young career. Working at the intersection of biology and business, the CIOPORA team supports plant breeders as they face a rapidly evolving landscape. While at CIOPORA, I had the opportunity to study China’s emergence as a biotechnology superpower, analyze the regulatory ambiguity surrounding New Breeding Techniques, and evaluate how pending legislation will affect the horticulture industry.


It was an honor to work alongside the CIOPORA staff- a creative and passionate team that brings compassion and professionalism to everything they do. I am grateful for the time I spent with CIOPORA and will benefit from what I learned for many years to come."
