Areas of Expertise:
- Paleoclimate
- Sediment geochemistry
- Ice cores
- Climate change
- Radiogenic isotopes
- Atmospheric dust
I study past changes in Earth’s climate system using a combination of field and laboratory approaches. I am interested primarily in understanding how and why the atmospheric circulation has changed through time and the impacts these changes have had on terrestrial and marine environments.
My research to date has focused on three major themes: 1) the impact of dust on marine ecosystems, 2) reconstructing past changes in mid-latitude wind belts, and 3) the transport of aerosols from explosive volcanic eruptions.
