Opportunities available for graduate, undergraduate, and postdoctoral research in paleoceanography, paleoclimate, and stratigraphy.

Please contact me for more information. Potential projects:

Is the climate more stable when it's warm? Evidence from the last 5 million years
Create a detailed reconstruction of the last glacial cycle
Study ocean circulation changes over the last 2 million years
Estimate age uncertainty in paleoclimate records

What does this mean?

Simple, non-technical explanations of what I study and why. Also, PowerPoint slides for teachers.

Data & Software

Match & Autocomp Software [Lisiecki and Lisiecki, 2002]
LR04 Benthic Stack [Lisiecki and Raymo, 2005]

Research Interests

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, 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.
