Projects

Trace metal and nutrient geochemistry

The weathering of trace metals and nutrients on land, their transport into the marine realm, and partitioning in sediments.

Redox through Earth history

Redox evolution of the ocean and atmosphere in the Archean, Proterozoic, and Paleozoic, as well as its effects on the biosphere and global elemental cycles.

Phosphogenesis

The generation of phosphate-rich minerals and sediments. The preservation of microbes in apatite and their role in its nucleation and growth.

Weathering environments

Weathering environments as sources of nutrients to the biosphere and archives of Earth's atmospheric composition.

Amber geochemistry

The provenance of amber deposits as revealed through their stable isotope composition and spectral characteristics.
