Dr. Alan Rempel

2005 Young Investigator Award

The AGU Cryospheric Focus Group is pleased to announce that

Dr. Alan Rempel (biography)

Has been chosen to receive the 2005 Young Investigator Award

for his significant contribution to Cryospheric Science and Technology.

This award was presented to Dr. Rempel during the Polar Reception at the Fall AGU meeting.

     The Cryosphere Focus Group Young Investigator Award is given to Dr. Alan Rempel in recognition of his outstanding research achievements in the broad area of cryospheric science.

     Dr. Rempel is a young scientist with excellent physical insights and a strong curiosity about the processes in the natural world. He is uniquely positioned to contribute to the quantitative understanding of cryospheric processes, based upon his background in mathematics, geophysics and engineering physics. This background has enabled Dr. Rempel to use powerful mathematical techniques when exploring complex geophysical problems. Dr. Rempel also has considerable experience as a working geophysicist, which helps him to identify worthwhile problems to address.

      Dr. Rempel’s latest work has concerned investigating the underlying processes of frost heave (the geophysical mechanism by which large-scale swelling of water-saturated soils occurs during prolonged periods of freezing. This work has included the development of a new model for frost heave that takes into proper account the intermolecular forces driving the phenomenon and determines the conditions under which different modes of behavior occur. Dr. Rempel’s theoretical work on frost heaves underpins our evolving models of frost heave dynamics and the evolution of particulates in permafrost.
