I am a paleoceanographer/marine
geologist who uses geochemical analyses of marine sediments to understand
how and why past climates have changed.
Current research
projects include developing high-resolution records of Holocene changes
in North Atlantic surface and deep ocean circulation and understanding
the Holocene history of the northwest African monsoonal system.
I've had a continuing interest
in Pliocene-Pleistocene African paleoenvironmental changes and their
relationships to evolutionary junctures in human evolution as well
as understanding the role of the tropical oceans in the mid-Pliocene
onset and amplification of glacial cycles.
