Research

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 ExoMars rover landing. As part of Mars Science Laboratory we study the composition and mineralogy of the Mars surface. One of our themes is disentangling the compositional effects of igneous clasts detrital minerals and low temperature alteration in the sediments. Our studies of martian meteorites include the first classification scheme of the shergottites based on trace element abundances. We study the phyllosilicate - ferric saponite and serpentine - and carbonate within the nakhlites and seek to understand these in the context of Mars' carbon cycle. 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 Diamond synchrotron.
