RESEARCH INTERESTS:

My research program primarily addresses three topics: the mechanisms of climate change, the controls on the global carbon cycle, and the measurement of geologic time. These subjects are fundamentally interrelated, as there are linkages between climate and the carbon cycle, while the establishment of reliable chronologies is essential for evaluating climate forcing mechanisms and determining rates of climatic and biogeochemical change in Earth's past. My interdisciplinary approach to investigating these topics integrates data (primarily geochemical, sedimentologic and stratigraphic) with novel modeling and statistical techniques, to unravel the history of the climate system, oceans and geosphere.

While I am involved in a wide range of geoscience research, at present I am especially active in the development of quantitative approaches for the construction and evaluation of astronomical time scales, the intercalibration of astrochronologic and radioisotopic data, and the evaluation of Earth System responses to orbital-insolation changes.
