Our laboratory research group focuses on the cross-disciplinary intersection of geology and molecular microbiology (Geobiology), with emphasis on the emergence and survival of Life within the context of dynamic Earth processes. Results have direct application to a wide variety of pressing societal interests that range from energy and human medicine to environmental sustainability and space exploration. Our active research projects include studies of: (1) applications of sedimentology, geochemistry and molecular microbiology to oil and gas exploration and production; (2) quantification of the rate, mode and tempo of microbial evolution in response to steep gradients using a microfluidic test bed called the GeoBioCell; (3) the control of sea surface temperature on coral reef ecosystems, coral skeleton synthesis and the global emergence of infectious marine diseases; (4) the response of heat-loving (thermophilic) bacteria to changes in hot-spring flow rate, chemistry and temperature; (5) the timing and hydrology of the last flow of water in ancient Roman aqueducts; and (6) understanding human kidney stone formation with integrated geobiology approaches.
