I am interested in climate change through the lens of paleoclimatic, paleo-oceanographic, and paleo-environmental studies.

I am determining how atmospheric temperatures have varied at high altitudes since the last glacial maximum (~20,000 years ago) by analyzing the 18O18O content of O2 trapped in glacial ice cores. Linking these temperature variations with temperature records at ground level give us new constraints on atmospheric dynamics in different climates, when greenhouse gas concentrations were different from today.
