Ben Gill is a geochemist and sedimentary geologist that specializes in reconstructing the present and past chemical cycles on our planet. Much of this work is focused on intervals in the Earth’s past that contain major climatic and environmental changes, as well as, major mass extinction events. His research combines classic sedimentologic and stratigraphic studies with geochemical and numerical modeling techniques.
Broadly, my research concerns reconstructing past environments and ocean chemistry and their relation to the evolution of life on Earth. In particular, I utilize different geochemical and numerical modeling techniques to help constrain the past cycles of biologically important elements (carbon, sulfur, iron and molybdenum). At the core of my research is the integration of geochemical data with the sedimentary and paleontological record.
