Georgia is sedimentologist within the Surface Geoscience Department. Her research interests focus on climate variability in recent periods and past warmer climates, including Antarctic Ice Sheet and sea-level change. She analyses the statistical frequency of physical and geochemical characteristics of shallow-marine and deep-marine sediment cores.
