Our research covers a wide range of areas spanning the Earth’s inner core, outer core, lower mantle, upper mantle, the lithosphere, the surfaces and interiors of the Moon, Mars and Venus, meteorites, and, more recently, the evolution and interiors of the icy moons such as Titan. The overarching rationale is to understand the properties, behaviour and evolution of the Earth and the other planetary bodies, and their place within the solar system.
