Biography
Prof. Marshak was on the faculty in the Department of Geology for 35 years, and became emeritus in 2018. He served as Department Head of Geology for 8 years, and then as Director of the School of Earth, Society, and Environment for 10 years. In addition to research in structural geology and tectonics, he maintains a strong interest in geoscience education. He authors or co-authorrs college textbooks in introductory geology, Earth Science, and structural geology, most of which are published by W.W. Norton & Company. He also has developed a MOOC (massive open online course) offered through Coursera.

Research Interests
Prof. Marshak's research involves structural geology, tectonics, and field geology. He has been involved in research projects in the Midcontinent, the Appalachians, and southeastern Brazil, and studies a variety of issues including: the development of tectonic structures and unconformities in cratons; the development of tectonic foliations in rocks; the formation of fold-thrust belts; and crustal evolution during the Precambrian.
