Research Interests
I use lake sediments to understand past climate changes around the world. I have previously worked in Greenland, reconstructing past tempertaure changes along the west coast over the last 11,000 years (the Holocene). I am currently involved with projects in Alaska, the Yukon, the western US (Utah), the Azores and Peru exploring temperature changes and drought history. I specialize in measureing oxygen isotopes from organic materials from lake sediment cores. My favorite proxy is oxygen isotopes measured from chironomids (the aquatic larval state), aka non-biting midges.
