Dr Katy Hayden, Plant Health Officer
Background
Katy is an evolutionary ecologist and RBGE’s Quarantine and Plant Health Officer. Her research is focused on the evolutionary changes that may drive or be driven by new host-microbe associations, and on appropriate management responses. Her work bridges Science and Horticulture, investigating best practice for biosecurity for a conservation organisation, and communicating her work to practitioners and the public.
Katy came to RBGE after a postdoctoral fellowship working with the Tree-Microbe Interactions Group at INRA Nancy, and postdoctoral and doctoral work in the Forest Pathology & Mycology Lab at UC Berkeley. Her first experiences in the intersection of plant and fungal ecology were with the Parker and Gilbert Labs, as an undergraduate at UC Santa Cruz.
