Ellie Nichols is a PhD student at HIE. Her research focuses on determining the physiological causes of eucalypt dieback, with an emphasis on hydraulic and thermal tolerance for drought and heat. This work is supported by the NSW Environmental Trust and will help to understand the causes of eucalypt dieback associated with increasing temperatures and drought risk.

Amy Smart is a PhD student at HIE. She is researching the resilience of world heritage listed Gondwana rainforests of NSW to increasing drought stress and bushfire risk. This includes quantifying the vulnerability of rainforest tree species to drought stress and tracing the recovery of these forests from the Black Summer bushfires.
