Beccy Ganley



Dr Rebecca Ganley (Beccy) is a forest pathologist with experience in foliar diseases of commercial tree species caused by fungi and oomycetes. Beccy’s research includes identifying ways to manage diseases and increase tree resilience for diseases that are problematic in commercial plantation, urban and native trees. She is an active researcher in Better Border Biosecurity (B3), involved in biosecurity research that includes identifying and analysing the risks of overseas pathogens.
