I study climate change and its impacts on ecosystems and societies. A particular focus is drought and water resources. In recent years I have been engaged in issues of sustainability and bridging the academic, governmental and business spheres to enhance efforts in sustainability. A specific interest is strategies to sustain California agriculture, cities and ecosystems in the face of growing human demands and climate change.
I maintain very active field and laboratory research. In our lab we reconstruct past climate change and impacts through the use of fossil pollen, fossil stomates, plant macrofossils, insect remains, tree-rings, geochemistry and historical records. We also do work on issues of current and future environmental change with a focus on water scarcity. My lab facilities are relatively extensive and consist of four rooms with full facilities for pollen and plant macrofossil processing and analysis, tree-ring analysis and elementary sedimentological analysis. Field equipment includes livingstone and hiller sediment corers, tree-ring corers and chainsaws, GPS, radios, and misc. field camp supplies. Areas of active field research include California, the northern Great Plains and adjacent Rocky Mountains, the North American subarctic, Russia and Siberia and Egypt.
