My research focus seeks to understand the causes and impacts of environmental change that occurred in the past, particularly during the Holocene (last 10,000 years). I believe that through a better understanding of our past interactions with the environment we will be better prepared to understand future impacts of global environmental change. In order to understand variations in climate or environmental change during time frames before written records I use biological and non-biological materials preserved in the geological record, primarily in lake and wetland sediments. For instance, one of my laboratory specialties is in pollen analysis (palynology). Pollen from trees, shrubs and herbs is preserved over time in lake sediments. The pollen is identifiable and can be used to understand how the vegetation for a region has changed because of climate influences, geomorphic changes or through human agency.
I have been collaborating with an archaeologist in Oaxaca, Mexico for the past decade. The ultimate goal of the project, which is funded by the National Science Foundation, is to provide a detailed understanding of human land interactions in the Lower Rio Verde watershed. This entails undertaking high resolution paleoecological reconstructions at multiple lake sites within the watershed. The number of study sites in the region provides a novel approach to examining questions of how people have used the landscape through time and coupled with our detailed understanding of the regions archaeology we will be able to examine how cultural/societal changes also impacted spatial use of the landscape.
I am beginning a new project that focuses on understanding climate changes over the past 1,000 years within the Bay Area. This project which is a joint collaboration with U.C. Berkeley will examine the paleoclimate proxy record archived in estuarine and wetland deposits from the Bay region. My Doctoral dissertation work focused on the Bay and so it is great to be returning to the Bay marshes.
I run the Sonoma Quaternary Lab (SQUAL). This lab focuses on providing students with hands-on research experience in physical geography. The lab is equipped with light and stereo microscopes for paleoecological analyses as well as a variety of equipment for different sedimentary analytical techniques such as grainsize and humification analysis.
