Impact Cratering is an important planetary and geological process, affecting the surface of almost all planets and satellites in the solar system. Studying impact cratering is challenging because the Earth's impact record has been severely affected by other geological processes and impact structures on other planets can only realistically be studied by remote sensing techniques. Furthermore, all of the processes in an impact cratering event cannot be simultaneously reproduced by experiments in the laboratory. Numerical impact simulations provide a way to investigate the dynamics of impact cratering at scales unachievable in the laboratory, however, numerical impact simulations rely upon a good understanding of the physical processes during cratering and upon comparison with observational and experimental results.

My work combines observational and experimental methods with numerical modelling to understand the highly dynamic processes associated with impacts. More specifically, in recent years, my research has focussed on dynamic rock failure, complex crater formation, and shock metamorphism.
