In my laboratory we study a diverse array of environmental microbes. A collaboration with colleagues in the Department of Biology examines the impact of leaf-dwelling microorganisms on the severity and spread of Sudden Oak Death disease caused by Phytophthora ramorum. Research carried out in conjunction with scientists at the Lawrence Berkeley National Laboratory Infrared Structural Biology Program investigates the cellulose-degrading capacity of alkaline tolerant bacteria as well as the process of rapid root abscission in the floating water fern Azolla. Another major research effort of my lab is the development of affordable systems for concomitant bioremediation and bioenergy production. A multi-year project with the City of Santa Rosa tested the capacity of channelized scrubbers to remove residual nutrients and other pollutants from treated municipal wastewater and opitimized anaerobic digestion of the harvested wetland biomass, mixed with agricultural by-products from local dairies and wineries, to produce methane gas.
