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.
