Research interests

Darrell Kaufman studies geologic records of environmental and climatic changes that took place during the recent past. Darrell studies lake and glacial deposits that provide an archive of long-term climate variability. Because dating of geological materials is pivotal to understanding the timing, rates, and regional extent of paleoclimatic changes, Darrell is particularly interested in geochronology, especially amino acid geochronology and tephrochronology. And, because accurate dating of geologic deposits is predicated on understanding the geologic context of the dated materials, Darrell has a strong emphasis in field geology. Darrell has been involved in a variety of field-oriented projects, principally in the Arctic where past environmental changes have been most pronounced and where current climatic changes are strongest.
