I am an organic geochemist with a particular interest in the power microbial biogeochemistry. Microscopic organisms have been shaping their environment since the beginning of life on Earth. Lipids are incredibly resistant molecules, and are preserved over long periods of time in the geologic record, acting as chemical fossils to these microbes. Using lipids to extract information about the environmental conditions in which these organisms once lived, I aim to develop biomarkers for specific microbial processes within biogeochemical cycles. Currently, my research projects focus on aerobic methanotrophy and anearobic ammonium oxidation. I also use a combination of genetic, isotopic, and lipid work to understand modern microbial processes. Ultimately, biomarkers can trace back the influence of microbes during extreme climatic events.
