Dr Ceridwen (Crid) Fraser
I am broadly interested in the influence of environmental conditions, including past and future environmental change, on global patterns of biodiversity. I use a wide range of techniques to address research questions, including ecological and genetic approaches, and have a particular focus on the high-latitude ecosystems of the Southern Hemisphere (the sub-Antarctic islands and Antarctica), which offer unique opportunities for testing hypotheses about dispersal and survival in extreme environments.
I have an undergraduate degree in conserving cultural materials (paper conservation), but did another in marine science when an early-life crisis sent me hurtling back to my dream of being a marine biologist. My Honours year was spent working on polychaete worms at the Australian Museum. I then moved across the ditch to study for my PhD in the Department of Zoology at the University of Otago (New Zealand), graduating in 2009. I worked as a postdoctoral fellow with the Allan Wilson Centre for Molecular Ecology and Evolution (hosted at the University of Otago), followed by a postdoc in the Biological Control and Spatial Ecology group at the Université Libre de Bruxelles, Belgium, before moving to the Australian National University in mid 2012 to take up a position as a lecturer in the Fenner School of Environment and Society.

Collecting bull-kelp (Durvillaea antarctica) samples on subantarctic Marion Island, 2007
I have several upcoming projects that could involve Honours or postgraduate students, such as:
- The role of volcanoes in maintaining biodiversity in the Antarctic throughout past ice ages. Specifically, I have some exciting opportunities for Master and Honours students using DNA to address this question in
--> Antarctic mosses
--> Antarctic invertebrates (springtails)
- Long-distance dispersal of parasites with their hosts
- Determining the sources of invasive species on sub-Antarctic islands
- Southward range shifts in south-eastern Australian species

Katie is studying population connectivity, host specificity and genetic / species diversity in ticks and other ectoparasites affecting various penguin species throughout the Southern Hemisphere. For more information, see Katie's web page, by clicking here.
