The mission of the Talbot Reseach Group is to improve our understanding of the biological sources and geological fate of the hopanoids, aiming to extend the ways in which they can be applied as marker compounds. Our research is broad in scope, ranging from the development of analytical techniques for the study of these complex molecules to the bacterial sources of hopanoids in modern environments to their diagenetic reactions and the application of hopanoids as biomarkers of biogeochemical processes in ancient sedimentary rocks.
