Research Interests

I study past variability of ocean circulation and the climatic impacts of those changes. My projects include reconstructing ocean circulation during the last Ice Age, during abrupt climate events that occurred as the large Ice Age continental ice sheets collapsed, and during the last 10,000 years in the absence of large ice sheets. With my many collaborators, I also research how these ocean circulation changes and other factors influence tropical rainfall and vegetation.
