In the EDGElab (Ecosystem Dynamics in Geochemical Environments), we are interested in investigations and experimentation that explore the interactions between microorganisms and their environments, specifically in ecosystems that present environmental challenges. These include [but are not limited to], hydrothermal systems, high and low pH systems, systems that access the "deep, dark biosphere," and processes of biomineralization (biofilms, microbialites, microbial mats). We also think about Astrobiology and life in Early Earth environments, and how these relate to life on current Earth.
I'm also interested in microbial processes in geochemically interesting environments, focussing on interfaces between microorganisms, fluids, and minerals. This includes biogeochemical cycling in hydrothermal systems, springs tapping into the "deep" biosphere, and systems where biomineralization is occurring. I use molecular (genomic), microbiological, geochemical, and isotopic parameters to identify the metabolic strategies, nutrient/energy requirements, and geochemical signatures (lipid biomarkers) of so-called "extreme" environments. My focus over the next several years will be carbon, nitrogen, and energy cycling in hydrothermal sediment and biofilm communities, serpentinizing springs, and caves. I also have a long-standing interest in applications of Earth-analog environments in the study of Astrobiology and life in early Earth ecosystems. Selected Publications (* student):
