My research 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 an understanding of our past human-environment interactions we will be better prepared to understand future impacts of global environmental change.   I use biological and non-biological materials preserved in the geological record, primarily in lake and wetland sediments to understand variations in climate or environmental change during time frames before instrumental records existed.  

I have several ongoing research projects. I am collaborating with archaeologists on several projects in Mexico.  Research in Oaxaca focusses on developing a high-resolution climate and environmental record for the Classic to Postclassic periods of Mesoamerican history when profound cultural change occurred.  Research in Guerrero focusses on geoarchaeological and paleobotanical analysis soils from a rock shelter.   These deposits also encompass a period of critical cultural change as they span the period of pre- and post European contact.  Both projects are funded through grants from the National Science Foundation. 

Closer to home, I have begun a project to reconstruct the paleoecology of ancient wetlands which are being exposed during construction work in the city of San Francisco.  These deposits offer a unique window into environments that are now severely disrupted or extirpated and so will provide valuable information for restoration projects.   

I run the Sonoma Quaternary Lab (SQUAL).   The lab is equipped with light and stereo microscopes for paleoecological and dendrochronological analyses, as well as a variety of equipment for different sedimentary analytical techniques, such as grainsize and humification analysis.

If you are interested in finding out more about the SQUAL lab, as well as undergraduate and graduate research opportunities please contact me.
