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 phosphorous 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
