Profile

FOM-NWO Computational Sciences for Energy Research Fellow and Assistant Professor

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
