I am a soil scientist by training and aim to do interdisciplinary research using molecular microbial ecology tools to study and characterize microbes that have important functional roles and ecological implications in our biosphere. My research in Biosphere 2 is focused on studying microbial community diversity patterns on a landscape scale and working with other researchers at the interface of microbiology, hydrology, and geochemistry. Using  the LEO hillslopes as a system, my goal is to determine microbial community diversity across length, breadth, and depth of the landscape, as affected by controlled rainfall regime and geochemical weathering of the slopes. I am also studying microbial communities that potentially contribute to rock weathering and soil formation over time and space.
