Jim is a current Research Postgraduate supervised by Prof. Martin Siegert and Prof. Tina van de Flierdt. By using geochemical techniques to trace the provenance of glacial sediments, his research aims to reconstruct the history of the Antarctic ice sheets, with a current focus on the Miocene. He is also interested in integrating radiogenic isotope provenance proxies with numerical ice sheet modelling.
