Over the past six years her focus has been on building geologic models of the crevasse splay and point bar deposits of the Cretaceous Illes Formation outcrops, Rangely Colorado. Previous research involved the Brushy Canyon deep-water sandstone outcrops of West Texas, conducting field work and producing reservoir models of the outcrops. As a Post-doc at the University of Wyoming, Dr. Carr was involved in outcrop and subsurface studies of the eolian Tensleep Formation in the Big Horn and Wind River Basins of Wyoming. Dr. Carr received her Bachelors and Masters degrees in Geology from University of Texas at Arlington. In 1994 she received her Doctorate from The University of Texas at Austin working with Gary Kocurek on the Entrada Sandstone of Utah. Dr. Carr has authored several papers on eolian sedimentology, deep-water sand deposition and building deep-water sandstone reservoir models.
