Research

I am a paleoclimatologist interested in using multiproxy approaches to provide insights into past changes in the Earth’s climate, and the environmental consequences of these changes. To do so I study the climate signal preserved in a variety of geological archives ranging from paleosols, marine and lacustrine sediments and glacial deposits over timescales ranging from interannual to millions of years.

My laboratory uses a variety of tools including traditional and compound specific stable isotopegeochemistry, organic molecular paleoclimatology, high-resolution scanning micro x-ray fluorescene (m-XRF) and cosmogenic surface exposure dating, I am especially interested in the use of annual sediment records in the development of high resolution climate reconstructions. A key component of my current research involves collaboration with modelers at the Jackson School and elsewhere to improve our interpretation of the paleoclimate proxy record and the mechanisms driving past and future climate variations.

Ongoing projects in my laboratory span the globe, including West Africa, tropical South America, Asia, the US southwest and the Arctic. If you are a prospective graduate student and this sounds interesting, check out the opportunities link and feel free to contact me.
