Claire is a lecturer in green infrastructure, based at The University of Melbourne’s Burnley Campus. Her main research interest involves using plants to make cities more liveable.
Claire’s current research is on using green roofs for stormwater mitigation and improving biodiversity in Australian cities.
As green roofs are difficult places for plant to survive, much of her research has focused on the drought tolerance and water use strategies of native Australian plants, including granite outcrop vegetation.
Recently her research involves using natural ecosystems as mimics to design optimal green roofs. This includes investigating the role plant diversity has on the stormwater and cooling benefits of green roofs.
Other research interests include improving water and nutrient retention of green roof substrates, the potential use of vegetables in rain gardens and using Australian shrubs in designed plantings (The Woody Meadow Project).
