Dr. Caldwell has long been interested in the
evolution of the Western Interior foreland basin, with an emphasis on
the southern Interior Plains of Canada. His work has focused on
foraminiferal and molluscan biostratigraphy, and paleogeographic
evolution with an emphasis on marine cyclicity and its eustatic and
tectonic controls. Dr. Caldwell's co-authored work, Evolution of the
Western Interior Basin, is considered a landmark in Cretaceous geology.
He is a former Vice-President (Research) of the University of Western
Ontario, a Fellow of the Royal Society of Canada, and an Officer of the Order of Canada.
