WELCOME

I am a carbonate sedimentologist-stratigrapher and focus my research on paleoclimatologic and paleoceanographic change in deep time (pre-Cenozoic). Within a detailed cyclostratigraphic and sequence stratigraphic framework, my students and I utilize a range of stratigraphic and geochemical tools to evaluate paleoenvironmental change occurring on time scales ranging from millennia, orbital (104-105 yrs), My-scale, to many tens of millions of years. This research includes field-oriented cyclo- and sequence stratigraphic studies across large Precambrian, Paleozoic, and Mesozoic carbonate platforms to understand the evolution of carbonate platforms, the origins of common stratigraphic cyclicity during greenhouse (warm) through icehouse (cool) climates. Geochemical techniques focus on oxygen and carbon isotopes from marine apatite and calcite, and Nd, U, Sr radiogenic isotopes, rock magnetics, and trace elements to detect changes in continental weathering and marine anoxia.

Field areas include many parts of the western U.S. (Nevada, Utah, Wyoming, Montana, Idaho, New Mexico, Arizona), western Canada, northern and central Mexico, and Europe (Czech Republic, southern France, northern Spain).
