Our group includes researchers (faculty, post doctoral scholars, graduate students, and undergraduates) whose common interests converge on the role of biogeochemical cycles in modulating ocean-climate interactions through Earth history.  Research projects span depositional environments from terrestrial to marine and time periods from Proterozoic to modern. Methodologies in use by group members include radiogenic and stable isotopic techniques, bulk elemental signatures, geochemical modeling, sedimentologic and stratigraphic methods, paleobiology, and high resolution geochronology (integrating orbital time scales with radioisotope age determinations). A partial list of publications by members of the group provides a more detailed picture of our activities and interests.
