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)
