Research Interests

My interests include (but are not limited to) sedimentary geochemistry, Earth history, the carbon cycle, paleoceanography, and paleoclimatology. I use geochemical tools to explore the interactions between the oceans, sediments, the rock cycle, and the climate system. My work involves samples of many different ages (Archean through Recent) and from a broad range of locations and environments, with a particular focus on the sedimentary archives of carbonates and evaporites.

Some active projects:

• geochemistry of evaporites from Baffin Island, Western Australia, and Oman
• carbonate diagenesis and pore fluid composition in the Maldives
• Paleoproterozoic sedimentary records from Fennoscandia
• authigenic carbonates from methane seeps on the Norwegian shelf
