Areas of interest
- Interactions of sedimentary organic matter with inorganic and aqueous species and especially, application of microbial biochemistry to geological problems - self-organisation and controls on optimised dissipation of chemical potential energy
- Astrobiology - definition of generic inorganic biosignatures and quantification of energy budgets for biotic processes
- Controls on the chemical composition of basinal brines, including development of new, natural geochemical tracers of origin.
- Integration of chemical, microbiological and physical processes to understand and remedy environmental pollution problems.
- Palaeo-oceanography and quantitative palaeoclimatology.
- Clastic sediment diagenesis - understanding of specific processes and integration of effects from pore-scale to basin-scale diagenesis, with application to hydrocarbons.
