Dr. Tim Clarey
Director of Research
Geology, Dinosaurs


Dr. Tim Clarey received a Master of Science in Geology in 1984 from the University of Wyoming and a Master of Science in Hydrogeology in 1993 from Western Michigan University. His Ph.D. in Geology was received in 1996 from Western Michigan University. From 1984 to 1992, Dr. Clarey worked as an exploration geologist at Chevron USA, Inc., developing oil drilling prospects and analyzing assets and lease purchases. He was Full Professor and Geosciences Chair at Delta College in Michigan for 17 years before leaving in 2013 to join the science staff at the Institute for Creation Research, having earlier conducted research with ICR in its FAST program. He has published many papers on various aspects of the Rocky Mountains and has authored two college laboratory books. He and his wife, Reneé, are co-authors of the children's books Big Plans for Henry, Henry Explores the New World, and Henry and the Ice Age.
