I am interested in the way that various elements, but principally nitrogen, are cycled in microbial mat and stromatolite communities. Microbial mats are often found in extremely nutrient poor environments. I am interested in knowing the ways in which nitrogen is obtained by mat microorganisms in these nutrient-poor environments. In addition, I am measuring the production and consumption of trace gases in microbial mats and stromatolites. The detection, and interpretation of biogenicity of “biomarker” gases (particularly methane) is very important in our search for life on Mars and even on extrasolar planets. We need to know more about the way in which microbial communities affect atmospheric levels of these trace gases.
