My research aims to form and test hypothesis of global change in deep time, particularly concerning the early evolution of microbial life and its environment. Specifically, I integrate field, petrographic and geochemical work to try and reconstruct marine ecosystem dynamics, and the availability of micronutrients such as Mo, Cu, Fe, Zn, Cd and Ni which may have had a limiting/co-limiting effect on primary production and hence the distribution of specific microorganisms. My research also aims to further our understanding on planetary climate stability, the processes and feedbacks that give rise to it, and how these have evolved through time.
