Research Interests

My research focuses on reconstruction of paleoclimate and environmental change using chemical proxies preserved in sediments of lakes and oceans - in particular changes in temperature, hydroclimate, and the influences of these parameters on ecosystems. To understand the biogeochemical processes that lead to a given chemical proxy, we must also understand the processes in modern aquatic systems that result in those proxies. Thus, my research combines studies of modern and ancient aquatic and sedimentary systems, with a goal of understanding how changes in environmental conditions influences biogeochemistry, and ultimately how that is recorded in the sedimentary archive. Major study sites have included East African rift lakes, Chilean Patagonia, Mexico & Guatemala, the southwestern USA, and the Laurentian Great Lakes.
