DR. STEVEN BOYER holds degrees in geology from Bucknell University (Lewisburg, PA; BS 1972) and Johns Hopkins University (Baltimore, MD; PhD 1978). Dr. Boyer has worked in numerous geologic provinces: the central and southern Appalachian Mountains; the Utah-Wyoming and Brooks Range thrust belts; the interaction of basement-involved structures and thin-skinned thrusting in Montana; the Basin and Range extensional province (Utah and Nevada); and inversion tectonics of the back-arc region, Kangean Island and vicinity, Indonesia. As an independent researcher and consultant, Dr. Boyer continues to study the geometry and kinematics of compressional terranes and the implications of mechanics and kinematics for the timing of trap formation relative to hydrocarbon generation and migration. Dr. Boyer's industry experience has included thrust belt oil field development, structural field schools, cross-section construction and balancing short courses, and consulting for several major oil companies. He has authored numerous refereed papers, which have appeared in such publications as the AAPG Bulletin, Journal of Structural Geology, as well as two papers in books on thrust belts and course notes related to cross section construction and balancing. Dr. Boyer received the Best Paper Award (Boyer & Elliott, 1982, AAPG Bulletin) from the Geological Society of America, and was named Distinguished Lecturer by the American Association of Petroleum Geologists (1992-1993). He is a Fellow of the Geological Society of America and has served as an associate editor of the Bulletin and Geology. Dr. Boyer is a Member and Fellow of the American Association of Petroleum Geologists, where he has also served as associate editor of the Bulletin.
