Biography
My main research focus is on carbonate mineral surface reactivity, dissolution and growth, with and without impurity ions. My approach is both experimental and theoretical; the tools I use to study carbonate minerals and other earth materials range from atomic scale computational chemistry and macroscale geochemical modelling to sophisticated analyses techniques such as synchrotron-based spectroscopy. Research areas of interest include: Mineral surface–water chemistry; Crystal growth and dissolution; Biomineralisation, Carbonate and Iron Sulfide minerals, Nano-particle properties
