I study marine sediment to reconstruct past changes in ocean circulation and terrestrial climate. Our group primarily uses stable isotopic and trace metal (Mg/Ca) analyses of foraminifera and terrigenous sediment geochemistry to investigate how and why climates have changed in the past. Recent research projects include: Holocene climate and ocean circulation variability
Some of my projects include:
- African climate change and Human evolution ( details )
- Holocene climate variability ( details )
- Abrupt onset and termination of the African Humid Period ( details )
- Cultural responses to Holocene climate changes ( details )
- Mollusc geochemistry and reconstructing seasonal to multiannual records of coastal oceean temperatures ( details)
