I am interested in how ocean productivity responds to large scale climate change. I have approached this through marine barite accumulation rates across the Eocene-Oligocene boundary, where a strong increase in productivity was observed before the onset of major glaciation. 

Additionally, I have looked at Pb isotopes as a tracer for dust and water fluxes. 

Currently, I am working on reconstructing paleoclimate conditions in Pennsylvanian cyclothems, a period of glacial-interglacial cycles before the onset of a greenhouse period. I am currently looking for a MS student for this project- go to the Opportunities page for more info!
