Personal profile
Biography
I'm an evolutionary biologist, with expertise in nutrition. Most of my work focuses on the relationships between insects and the plants they eat, and how these relationships are changing. I'm currently working in The Pollinator Futures Research Centre at Macquarie University to understand how changes in the nutritional environment driven by climate change impact pollinator fitness. Previously I worked as an EMBO Postdoctoral Research Fellow at UCL, where I studied the evolution of biotic interactions in the Brown Argus butterfly under climate change. During my PhD at Monash University, I have also undertaken research using D. melanogaster as a model organism to understand lifespan/reproduction trade-offs associated with diet, and local adaptations in nutritional and thermal tolerance along the Australian east coast.
Research interests
My research examines how nutrition shapes insect adaptation in changing environments. I am particularly interested in how climate change alters the nutritional quality of plants and floral resources, and how these changes affect insect performance, reproduction, and fitness.
I work across insect systems, including bees, butterflies, and Drosophila, to understand how nutritional environments influence life-history trade-offs, thermal tolerance, and the evolution of biotic interactions. A central aim of my research is to identify when changes in resource quality generate nutritional mismatches between insects and the environments they occupy, and how these mismatches affect their capacity to adapt or persist.
More broadly, I am interested in the role of nutrition in mediating ecological and evolutionary responses to global change, particularly in insect–plant and pollinator systems.
