BSc Tas., PhD Adel.
I grew up in Hobart, completing my undergraduate studies at the University of Tasmania in 1996, and a PhD in ecophysiology at The University of Adelaide in 2001. For the next couple of years I was a research fellow at Victoria University of Wellington (New Zealand) funded by The Royal Society, and afterwards spent periods at Colorado State University, the Australian National University and La Trobe University before moving to the University of Western Australia (UWA) in 2005 on an ARC postdoctoral fellowship. I started work at UWA as a teaching and research academic in 2009.

A consistent theme in my research is to determine the impact of the thermal environment on sex determination and survival in reptiles, and studying the reproductive biology of unusual frog species, from their egg physiology to sexual selection. My more recent research is more applied - aiming to understand the capacity of vertebrates to adapt to rapid climate change, and using models to inform preemptive management, such as assisted migration (see I now describe myself as a conservation physiologist.

Current lab members (below) work on sea turtles, freshwater turtles and crocodiles, small brown (but very interesting) frogs, Christmas Island skinks, and the spectacular birds and amphibians of Malaysian cloud forests:

PhD students: Sophie Arnall, Blair Bentley, Tabitha Rudin-Bitterli, Malcolm Soh, Jessica Stubbs, Emily Hoffman, Jon-Paul Emery

Hons/MSc: Alexandra Bouma, Deanne Cummins

Postdocs: Ruchira Somaweera

2016 lab volunteers/legends/interns: Tom Windsor, Savannah Victor, Marcus Lee, Nick Rodriguez, Brighton Downing, Natasha Harrison, Calum Woods

NOTE - I cannot offer additional PhD, MSc or honours projects at the moment, but there may be spaces opening up in the lab from 2018.
