Ceridwen Fraser is a biogeographer, currently serving as a Professor in the Department of Marine Science at the University of Otago in Dunedin, New Zealand.

She focuses her studies on ecology, evolution, climate change, and how they are all significant to the southern hemisphere, specifically at higher latitudes such as Antarctica.

After graduating from Macquarie University, Fraser spent a year studying polychaete worm ecology at the Australian Museum with Pat Hutchings.

[2] With her undergraduate and doctorate degrees, Fraser focused her research on understanding the patterns of global biodiversity through both molecular biology and earth sciences.

The scientists used these results as a conclusion that the ice sheets in the LGM reached lower latitudes than previously thought by the scientific community.
