Personal profile
Biography
I am a broadscale restoration ecologist with expertise in both terrestrial and freshwater ecosystems. My research examines the impacts of threatening processes on species decline and evaluates strategies for effective ecological restoration.
My PhD explored the ecological role of rocky habitats in restoring reptile populations within agricultural landscapes. This project experimentally quantified reptile responses to rock restoration and grazing, with outcomes applicable to surface rock removal regulations, national offset strategies, sustainable farming practices, and restoration programs.
I have contributed to large-scale water resource management projects, both nationally and internationally with CSIRO. I have also worked across a variety of fauna and flora monitoring programs, including freshwater fish, koalas, macropods, frogs and reptiles.
Currently, I am undertaking a Research Fellowship focused on climate adaptation strategies and wetland restoration actions aimed at enhancing ecosystem function and promoting recovery in Ramsar-listed wetlands. This research is vital for developing targeted management interventions that build ecosystem resilience to climate change, support long-term ecological health, and safeguard biodiversity in these globally significant wetlands.
Research Interests
My primary interests lie in restoration ecology, with a focus on understanding threatening processes and developing strategies to mitigate their impacts on biodiversity. My research focuses on designing and implementing well-informed field experiments to quantitatively evaluate the effectiveness and interactions of restoration activities to inform management activities to redress species decline.
