Dr Benjamin J. W. Mills


I am a biogeochemical modeller with a background in pure mathematics. I build computer models in order to investigate the processes responsible for long term changes in Earth's surface conditions. I also conduct field and laboratory work to collect data relevant to both present day climate change, and to changes that happened in the deep past.

Research interests

I am interested in the evolution of the current global climate state, the processes that have influnced Earth's climate through time, the links to the evolution of life, and the possibility of habitable conditions existing on other planets.

A key focus is on the variation of atmospheric carbon dioxide and oxygen concentrations over the last 1 billion years of Earth history, and the possible correlations with the development and radiation of plant and animal life. This work involves developing mathematical representations of global tectonic and biological processes, and combining these with geochemical data to test hypotheses about the major drivers of climate evolution.

I am always interested in new collaborations, please get in touch if you would like to work on an idea, join my group as a researcher, or apply for a PhD project.
