Research Statement: 

My group’s broad objective is to characterize and understand climate variability and change on multi-decadal to centennial timescales. Climate research is limited in its ability to understand these climatic variations directly from the instrumental record because such observations are not widely available for more than about 100-150 years. To circumvent this limitation, modern instrumental records are supplemented with climatic proxy records and climate model simulations to help characterize these low-frequency modes of change. Toward such ends, my research group uses numerical models, climate proxy records and statistical methods to better understand the variability of climate over decades to centuries. We have a particular interest in how multiple climate proxies can be combined to yield hemispheric and global maps of climate variability spanning the Common Era (the last two thousand years), and how climate models represent climatic change over this time period. Please see my research and publication pages for more information on my group’s research in these areas.
