Professor Benjamin J. W. Mills


I am a biogeochemist and numerical modeller who works on the evolution of the Earth System over geological time. I am interested in the changes in the surface environment that have made our planet habitable for complex life, what has driven these changes, and whether a similar trajectory might be possible on other worlds.

I lead the Earth Evolution Modelling Group, which built and maintains the SCION Earth Evolution Model – the world’s only 3D simulated planetary environment that can be integrated over billions of years. Our new ERC/UKRI project ‘SIM-EARTH’ is developing the second generaiton of this framework, and hopes to answer many exciting questions about how our planet works, and how planetary environments in general might be expected to evolve.

I am the chair of the Earth System Science Group of the Geological Socitey of London, and lead the yearly Life and Planet conference
