1988-1992 PhD Open University

My research and that of my team aims include to understand water-rock reactions in the martian crust and differentiation of the lithosphere. Remote observations by the CaSSIS and HiRISE orbital cameras enable us to see colour and high resolution views of Mars and plan for the planned ExoMars2028 rover landing and Mars Sample Return. As part of Mars Science Laboratory we study the composition and mineralogy of the Mars surface.

Our early Solar System research centres on analyses of primitive meteorites Comet Wild2 grains and analyses of Asteroid Itokawa and Ryugu grains returned by the JAXA Hayabusa missions. Embedded in our research are a range of analytical techniques - including electron microscopy and related techniques at the Diamond synchrotron.
