Research Summary

I am a biogeochemical modeller with an interest in the evolution of the Earth system over time. I am interested in determining the various factors which may have played a part in driving the Earth to its current state, and will continue to exert an influence far into Earth's future. I am also concerned with building an understanding of how and why Earth became habitable so that this information can be used in the search for habitable exoplanets.

At UCL, my research is focused on investigating the links between weathering, CO2 and temperature for incidents such as OAEs, glaciations (e.g. the Hirnantian), and the PETM etc. To do this I combine geochemical data with the development of mathematical representations of Earth processes, for instance: biological developments and changes in global tectonism, to understand the descent into, and escape from these climatic episodes.
