My research focuses on computational approaches to the interpretation of paleoclimate records. 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, 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 of simple, dynamic programming, and mathematical tools such as time series analysis, principal component analysis, and computational probability and statistics.
