Bill left a career in the energy industry that included posts as well-site geologist, field engineer, and explorationist in Wyoming, Angola, and Kenya, to earn a M.S. in geology as a means of better reconciling biblical history with the rock record. Adept in the field and lab, Bill has assisted in Grand Canyon field investigations of Mississippian and Cambrian strata and performed mineral separations on Precambrian mafic rocks for the purpose of isochron dating. He has also served as field trip director, public speaker, and has authored dozens of contributions for creationist literature. His current research interest is in sand injectites and their connection to large-scale movements of fluidized sand during the Flood.
