Current Research
Stable isotope and elemental geochemistry combined with petrography (optical and electron microscopy) of carbonate rocks and sediments for palaeoclimatic and palaeoenvironmental reconstructions, exploring connections between climate, biosphere and tectonics through all of Earth history, from the Quaternary to the Archaean.
Astrobiology and geobiology, including processes of microbe fossilisation and identification of ancient microbial fossils (see for example http://theconversation.com/the-hunt-for-life-on-mars-new-findings-on-rock-chimneys-could-hold-key-to-success-97998 and https://www.newscientist.com/article/2172262-these-eerie-rock-towers-may-have-been-built-by-microorganisms).
Diagenesis, particularly of carbonate rocks and sediments, distinguishing original from secondary (alteration) features.
Examining deposition and diagenesis of non-marine carbonates (microbial tufas, hot-spring travertines, soil calcretes and cave speleothems), including the impact of the arrival and diversification of vascular plants on these terrestrial carbonates, and on muddy Palaeozoic reefs. I do this using a combination of field techniques, petrography and (isotope and elemental) geochemistry. This work has both applied and academic relevance.
