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.

FAR-DEEP (Fennoscandia Arctic Russia – Drilling Early Earth Project) team member, examining the oxygen and carbon stable isotope record of Palaeproterozoic deep marine to shall marine and lacustrine carbonates from cores drilled by the ICDP, including regional vs global controls on the Lomagundi-Jatuli δ13C excursion and purported global glaciations in the Palaeoproterozoic.

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. I do this using a combination of field techniques, petrography and (isotope and elemental) geochemistry. This work has both applied and academic relevance.
