My research focuses on computational approaches to the interpretation of paleoclimate records. I believe that the integrated analysis of widely distributed paleoclimate records will yield important information about the climate system that cannot be obtained by studying these records individually. I am particularly interested in the evolution of Plio-Pleistocene climate as it relates to Milankovitch forcing, 100-kyr glacial cycles, the carbon cycle, and deep-ocean circulation. I also develop and distribute software related to age model development and stratigraphy. The analytical techniques I use most frequently are stratigraphic correlation, simple physical models, dynamic programming, and mathematical tools such as time series analysis, principal component analysis, and computational probability and statistics.
