Associate Professor of Earth Sciences
My overarching research objective is to understand how and why climate has changed and identify trends and sources of air pollution. My specialty is creating long (50-50,000 years) records of climate change and air pollution by analyzing chemical markers preserved in glacier ice cores. I also study data from weather stations and climate models to determine recent climate trends to differentiate natural cycles from human-caused changes. I am particularly interested in aspects of climate change that impact communities, including sea-level rise from melting glaciers, and the changing number and intensity of storms.
