Doctor Adam Frew
I’m interested in arbuscular mycorrhizal fungi, how they affect plants and the ability of plants to cope with herbivory.
I obtained my PhD from the Hawkesbury Institute for the Environment in 2017, where I studied the impacts of the soil environment on root feeding insects. I was then awarded an independent research fellowship at Charles Sturt University in Wagga Wagga where I continued to pursue my interests in belowground ecology by exploring aspects of how arbuscular mycorrhizal fungi affect plant performance and responses to insect herbivory. After this fellowship I took up an ongoing faculty position at the University of Southern Queensland teaching into a variety of environmental and sustainability subjects while continuing my research into mycorrhizal ecology.
I was awarded an ARC DECRA that explores how agricultural management shapes mycorrhizal fungal diversity and how community composition impacts plant defences against insect herbivores. At this point, the call to return to HIE was one I could no longer ignore, and I (re-) joined the institute in 2022.
