Prior to joining Colorado State University in 1976, Dr. Charlie was an Instructor of Civil Engineering at Michigan State University and an Assistant Professor of Civil Engineering at the University of Maine at Orono. Since joining Colorado State University in 1976, he has been a Fulbright Professor at the University of Khartoum and a Visiting Professor of Civil Engineering at Cornell University and at the University of Auckland (New Zealand). He has been Project Director for research on Explosive and Earthquake Induced Soil Liquefaction, Mine Tailings, Expansive Soils, Frozen Soils, and Organic Soils. He introduced sophisticated computer data acquisition devices for recording laboratory and field transient behavior of soils and under impact of explosives. Professor Charlie has also worked for various government agencies and private geotechnical engineering firms including the Bureau of Reclamation, the U.S. Peace Corps, the Agency for International Development, and the U.S. Air Force, and D'Appolonia Consulting Engineering. He has served as a geotechnical consultant to over 20 organizations located in Alaska, California, Montana, Utah, Wyoming, Maine, Michigan, Colorado, New Mexico, New York, Ohio, Wisconsin, Washington D.C., South Pacific, Europe, Africa, Canada, Asia and the Caribbean. Topics included earthquake and blast induced soil liquefaction, industrial wastes, tailings, expansive soils, organic soils, frozen soils, and blast damage.
