About the Author

My name is David Waltham and I am Profesor of Geophysics at Royal Holloway (University of London). In this role I teach a wide range of topics including oil-exploration, earthquake detection, climate-physics and Planetary Geology. My research involves computer modelling of everything from sand-grains to solar systems. If you have questions about the simulations on this website, you can contact me at d.waltham@rhul.ac.uk.
