The ALE Lab

We’re interested in the interactions between life and the environment on the early Earth. To address this, we 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. We then tie these constraints directly to geobiological records.
