Hey, I'm Alex (he/him).
I'm currently a postdoctoral researcher at University College London in the UK (until the end of December), researching climate change events which occurred millions of years ago. To do this I build biogeochemical numerical box models of the Earth system and investigate the influence of changes in processes such as tectonism on the climate. I then compare my results to geochemical proxy data, such as lithium isotope ratios, extracted from rocks.
For my PhD I did something similar, but my research focused on how atmospheric oxygen levels have changed throughout the course of Earth history and their possible links to evolution. I also spent a good chunk of time in the lab, helping to create a set of reference materials for the widely used iron speciation technique.
Broadly, I'm interested in the biogeochemical evolution of the Earth system, what this means and has meant for life on Earth and whether we might be able to apply this knowledge for finding life elsewhere in the Universe. If you have any theories that you want to test out with some modelling then feel free to drop me an email.
