Crid’s research focuses on understanding the processes underpinning the biogeography and evolution of Southern Hemisphere species. She uses both ecological and genetic techniques to address research questions, and has a particular interest in the high-latitude (polar and sub-polar) ecosystems of the Southern Hemisphere. She is an early-to-mid career researcher, graduating with a PhD from the University of Otago in 2009. After her PhD, Ceridwen undertook two short postdoctoral fellowships, one with the Allan Wilson Centre for Molecular Ecology and Evolution, New Zealand, and the other with the Free University of Brussels, Belgium, and is now a Senior Lecturer at the Australian National University. She has participated in many sub-Antarctic research field trips, working on Marion Island, Gough Island, the Falkland Islands, and Deception Island, and was the expedition leader on a research trip that visited all of the New Zealand sub-Antarctic islands in 2010. Her research articles have been highly cited and have received considerable media attention.

Ceridwen’s current projects include: assessing whether geothermal areas have sheltered biodiversity through past ice ages in the Antarctic; long-distance dispersal processes in the Antarctic and sub-Antarctic; and the biogeography and phylogenetics of some Antarctic marine and terrestrial organisms. For example, her and her students’ research topics range from the phylogeography of penguin ticks, to the spatial distribution of diversity in Antarctic mosses, and the dispersal of buoyant algae in the Antarctic Circumpolar Current.
