About the Lab

The research in our lab integrates physiological and ecological studies of modern microbes with field and laboratory experiments in microbial sedimentology to develop a quantitative understanding of various morphological and geochemical biosignatures found in sedimentary rocks. Our laboratory also investigates microfossil record associated with some of the major climatic and geochemical oscillations in the Neoproterozoic.
