Areas of research: I am embedded within the Deep time global change research group at the University of Exeter and jointly funded by the NERC GW4+ DTP and BGS. For my current PhD research, I am examining oceanographic and biotic changes in Australia during Oceanic Anoxic Event 2 (Cretaceous – Cenomanian/Turonian boundary) by:

Reconstructing changes in sea surface temperature before, during and after OAE 2 using GDGTs and the TEX86 proxy – looking for overall warming during the period, as well as possible short term cooling events.
Examining local oceanic productivity throughout the Cretaceous (with a special focus on OAE 2) using dinoflagellate cist assemblages, considering both oceanic upwelling and nutrient delivery from terrestrial sources.
Processing pollen grains and spores to reconstruct terrestrial vegetation changes in the region during OAE 2, and subsequently, changes in the hydrological cycle at this time.
