Postdoctoral Research Associate

Research Interests

Marine Biogeochemistry: Marine and terrestrial chemical sources and particle fluxes to ocean rocks and sediment; tracing fluxes through time; linkages between paleo-ocean chemistry, tectonics, and sedimentation; reconstructing patterns of ocean circulation and deepwater formation.

Analytical Geochemistry: Major, trace, and rare earth element analytical methods; Sr-Nd-Pb, isotopic methods; mineralogical determinations; multivariate statistical analysis of geochemical datasets.
