New collaborative (with the University of Geneva) project Long-term evolution of the Earth from the base of the mantle to the top of the atmosphere: Understanding the mechanisms leading to ‘greenhouse’ and ‘icehouse’ regimes funded by Sinergia programme of the Swiss National Science Foundation! There are 5 new PhD positions available! The project is a collaboration with 3 groups at the University of Geneva. See here.

I am interested in the thermo-chemical structure, dynamics and evolution of the interiors of solid planets and moons, including Earth, Venus, Mars, Mercury, Io and extrasolar super-Earths, focussing particularly on convection in the solid mantle and the associated dynamics of the lithosphere, which on Earth means plate tectonics. My main research tool is numerical simulation, using state-of-the-art numerical methods on high performance (massively-parallel) supercomputers to obtain more realistic, three-dimensional numerical models of dynamical processes than previously possible. Specific recent projects include:
