Microbes are, unquestionably, the most critical members of our biosphere. They exist in every habitat, playing a role in mediating atmospheric and ocean composition and governing elemental cycles in soils and sediments. The last two decades have been a watershed for microbiology, with major advances in genomic sequencing and other technologies that have fundamentally changed our view of microbial diversity and evolution. However, our understanding of what microbes are *doing* in nature –in particular the degree to which they influence biogeochemical cycles– is still in its infancy. My lab's research is aimed at better understanding microbial activity through i*n situ* and laboratory studies. To that end we develop technologies that allow us to better relate microbial activity to the environment, such as underwater mass spectrometers and stable isotope analyzers.
