Ceridwen Fraser

Senior lecturer, Australian National University

I have a couple of undergraduate degrees from Australia (University of Canberra and Macquarie University) and a PhD from the University of Otago in New Zealand. I worked as a postdoctoral fellow in New Zealand (University of Otago) and then in Belgium (Universite Libre de Bruxelles) before taking up a permanent position as a lecturer in the Fenner School of Environment and Society at the Australian National University in 2012. My research focuses on the biogeography and evolution of Southern Hemisphere species. I use both ecological and genetic techniques to address research questions, and have a particular interest in high-latitude (sub-Antarctic and Antarctic) ecosystems.
