Daniel uses stable isotope geochemistry and enrichment culturing to research the carbon cycle in the Samail Ophiolite in Oman, specifically focusing on the source of hydrocarbon gases. Ophiolites are slices of ocean crust and mantle that have been thrust onto continents, providing natural laboratories for the study of processes that occur deep inside Earth and on other bodies of the Solar System where water and rock interact. Weathering of ultramafic rocks in ophiolites and in other geological settings are known to mineralize large quantities of carbon dioxide, but the quantities and sources of gases they release, such as methane, and their biogeochemical impact, are less well understood.
