Research Interests

My research focuses on understanding the sensitivity of regional rainfall to global climate change. I use a ​variety of methods, ranging from geochemical and biological proxies to climate models. My work focuses on a paleoclimatic perspective, whereby past instances of climate change can be used as ‘natural experiments’ to understand the response of the atmosphere-ocean system to external forcing. Current projects include analyzing the role of tropical Atlantic variability in forcing Mesoamerican drought, studying the interactions of the midlatitude westerlies and monsoon systems, and analyzing reorganizations of subtropical rainfall during past warm intervals in Earth history.
