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,
Matlab programming, and mathematical tools such as time series
analysis, principal component analysis, and computational probability
and statistics (e.g., Bayesian statistics).
What does this mean? Simple, non-technical
explanations of what I study and why. Also, PowerPoint slides for
teachers.
Ted-Ed Lesson: What causes an ice age? Animated video suitable for K-12.

Author's Note: I have received many emails about this article asking
me what current climate changes should be expected based on orbital
forcing. Orbital forcing cannot be used to explain climate changes on
a scale of 100 or even 1000 years. The natural response that would be
expected is a very gradual cooling trend over the next 90,000 years or
so. However, it is uncertain whether this cooling trend would be
expected to start thousands of years ago
(e.g., Ruddiman)
or thousands of years in the future.
