Past Climate Research
My paleoclimatic research is primarily based on lacustrine records of climate change. These records typically span the Holocene and early Pleistocene. I have collected sediment cores from both North America and Central America. I study the pollen, diatoms, micro- and macroscopic charcoal, and other geochemical "proxies" to infer what environmental conditions were like in the past.
Here are a number of links to my various papers. I would also recommend checking out my academia.edu webpage for the latest papers as well as links to presentations materials.
