My research deals with the diversification of life, "rules"
that govern macroevolution, and the evolutionary dynamics of open ocean
plankton. I also have an extensive research program on climate and
evolution during periods of past warm climates.
I am particularly interested in: (1) the processes that initiate
large-scale evolutionary trends, (2) the role of environmental change in
structuring the biogeography and diversity of species, and (3) the mode of
species formation and extinction in the open ocean as a contrast with much
more intensively studied terrestrial systems. I also work on the climate
and evolutionary dynamics of periods of "extreme climate", such as the
Paleocene-Eocene Thermal Maximum, The Cretaceous-Paleogene Boundary, and
the Cretaceous Climatic Optimum, as well as the impact of climate variability
on modern ecosystems and human society. These studies are focused on
reconstruction of surface temperatures, deep ocean circulation, and
terrestrial climate/disturbance proxies.
I was an undergraduate in Earth Sciences at UC Santa Cruz, obtained a
Master's of Science degree at University of Arizona, Tucson, and my Ph.D.
at Harvard University in geology. In between these academic programs I
worked on the Condor Recovery Project for the State of California and as
director of the NRS Granite Mountain Reserve for the University of California.
Following graduate training, I was a research scientist at Woods Hole
Oceanographic Institution, on Cape Cod, Massachusetts until I became a
professor at UCSD in 2002. As a child, I lived in Hawaii and Chile. Today,
I have field research interests in the geology, paleontology, and natural
history of California, Nevada, Utah, and Wyoming. I have also been a
proponent and co-chief scientist for numerous oceanographic cruises of the
Ocean Drilling Program and Integrated Ocean Drilling Program.

The sediments being collected on Expedition 342 records Paleogene changes in both global climate as well as shifting ocean currents.
