Climate Sensitivity and Impacts

Narrowing the uncertainties in how Earth's climate will change in the future is one of the most pressing problems in all of science. I take a variety of approaches to address this problem, spanning detailed investigations of the physics controlling changes in the hydrologic cycle, to system-level analyses of the climate system which aim to reduce the uncertainty in Earth’s climate sensitivity.

Large-Scale Atmospheric Dynamics

My research on atmospheric dynamics combines theory, numerical simulations and observational analyses, as I seek to improve our understanding of the surface climate today, our ability to predict how it will change in the future and our interpretations of how it has changed over Earth’s history.
