I’m interested in the interactions between life and the environment on the early Earth. To address this, I use a combination of field work, sedimentary geochemistry and experiments to infer how oxygen levels and nutrient availability have changed through time on local and global scales. I then tie these constraints directly to geobiological records.

My specific research interests include:

• Origins of banded iron formation
• Patterns of metal availability in seawater through time
• Bio-availability of phosphoro in anoxic oceans
• The marine sulfur cycle in the modern ocean and deep time
• The origin and diversification of animals
• Changes in oxygen availability in the oceans through time
