Research

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
