(Please see my main profile pages, hosted by the Department of Anthropology and the Climate Change Institute, for more details.)
I am a geoarchaeologist who studies the effects on cultural development of climate change, particularly the prehistory of the El Niño/Southern Oscillation (ENSO) phenomenon, and environmental change, particularly rising sea level during the last deglaciation; also the development and organization of complex societies in the coastal setting. I also produce climate records from archaeological remains. My research is broadly interdisciplinary and most of my research colleagues on campus are in the School of Earth and Climate Sciences.
Most of my research takes place in Peru, but I have also worked in Guatemala, Honduras, and Cuba earlier in my career. I have been at the University of Maine since 1993.
