Stephen Marshak is a Professor Emeritus at the University of Illinois, affiliated with the School of Earth, Society, and Environment (SESE) and the Department of Earth Science and Environmental Change. His academic roles include former Director of SESE (10 years) and Department Head of Geology (8 years). He holds a Ph.D. from Columbia University (1983), an M.S. from the University of Arizona (1979), and an A.B. from Cornell University (1976).
Marshak’s research focuses on structural geology, tectonics, and field geology, with emphases on Midcontinent, Appalachian, and Brazilian geology. His work addresses tectonic structures, fold-thrust belts, and Precambrian crustal evolution. He has pioneered studies on the Great Unconformity, Ozark Plateau dynamics, and lithospheric boundaries like the Ste. Genevieve fault zone.
His awards include the Neil Miner Award (2012), Stillwell Medal (Australian Geological Society), and multiple teaching honors. He is renowned for textbooks such as Earth: Portrait of a Planet and for developing Coursera’s Planet Earth MOOC. His educational contributions span geoscience pedagogy, field geology training, and digital resources.
Recent research highlights crustal thickness variations in the U.S. Midcontinent using H-κ-c methods, magnetotelluric imaging of trans-crustal shear zones, and kinematic analysis of the Baraboo Syncline. Collaborations span geophysical data integration, continental interior tectonics, and interdisciplinary studies of cratonic evolution.
