Lee R. Kump is a Professor in the Department of Geosciences,
and an associate of the Earth System Science Center and
Astrobiology Research Center at the Pennsylvania State University.
A native of Minnesota, he received his bachelor's degree in
geophysical sciences from the University of Chicago in 1981, and
his Ph.D. in marine sciences from the University of South Florida
in 1986.
Dr. Kump is a Fellow of the Geological Societies of America and
London, and a member of the American Geophysical Union, the
Geochemical Society, and the Geochemistry Division of the American
Chemical Society. His research has been funded by the Environmental
Protection Agency, the National Science Foundation, NASA, the Gas
Research Institute, the Petroleum Research Fund of the American
Chemical Society, and Texaco. Dr. Kump became Associate Director of
the CIAR Earth System Evolution Program in 2004. Dr. Kump's primary
research effort is in the development of numerical models of global
biogeochemical cycles. His early work focussed on the carbon and
sulfur cycles, and on the feedbacks that regulate atmospheric
oxygen levels. More recently his emphasis has shifted to the study
of the dynamic coupling between global climate and biogeochemical
cycles. He studies the long-term evolution of the oceans and
atmosphere, using a combination of field work, laboratory analysis,
and numerical modeling.
James Kasting is a Distinguished Professor of Geosciences at
Penn State University. He received his undergraduate degree from
Harvard University in Chemistry and Physics and did his Ph.D. at
the University of Michigan in Atmospheric Sciences. Prior to coming
to Penn State in 1988, he spent 7 years in the Space Science
Division at NASA Ames Research Center. His research focuses on the
evolution of planetary atmospheres, particularly the question of
why the atmospheres of Mars and Venus are so different from that of
Earth. He is also interested in the question of whether habitable
planets exist around other stars and is involved with NASA's
proposed Terrestrial Planet Finder Mission(s).
Dr. Robert Crane received his bachelor's degree in physical
geography from the University of Reading, England, in 1976. He did
graduate work in polar climatology, microwave remote sensing, and
sea ice-atmosphere interactions at the University of Colorado's
Institute for Arctic and Alpine Research (INSTAAR) and the National
Snow and Ice Data Center, receiving a Master's degree in 1978 and a
Ph.D. in 1981. As a Research Associate in the Cooperative Institute
for Research in Environmental Sciences (CIRES), he continued his
work on the microwave remote sensing of sea ice.
He joined the faculty of the Pennsylvania State University in 1985.
Dr. Crane held a joint appointment in the Department of Geography
and in the Earth System Science Center from 1985 to 1993, serving
as Associate Director of the Center from 1990 to 1993. He was
appointed Associate Dean for Education in the College of Earth and
Mineral Sciences in 1993, and currently holds the position of
Associate Dean and Professor of Geography.
