From 1995 through 1997, Scott worked in private practice for Woodward-Clyde Consultants. After completing his Ph.D., Dr. Olson returned to private practice with URS Corporation and also taught geotechnical earthquake engineering courses at the University of Missouri-Rolla. He joined the faculty of the Department of Civil and Environmental Engineering at the University of Illinois in August 2004, and holds a 0% appointment in the Department of Geology.

Dr. Olson teaches several courses in geotechnical engineering: an undergraduate introduction to geotechnical engineering course (CEE 380), a mixed undergraduate and graduate course in applied soil mechanics (CEE 484), and four graduate courses on excavations and support systems (CEE 580), rock mechanics (CEE 586), applied rock mechanics (CEE 587), and geotechnical field measurements (CEE 590).

Dr. Olson is a member of the American Society of Civil Engineers, the Earthquake Engineering Research Institute, Canadian Geotechnical Society, the North American Geosynthetics Society, the International Society for Soil Mechanics and Geotechnical Engineering, and the Seismological Society of America. Dr. Olson previously was a member of the governor-appointed Missouri Seismic Safety Commission, and has served on numerous review panels for the National Science Foundation, National Cooperative Highway Research Program, and the U.S. Geological Survey. He is a licensed professional engineer and continues to participate in consulting projects with industry.

Dr. Olson has received several honors and awards for his research, practice-related, and teaching accomplishments. In 2003, the Canadian Geotechnical Society awarded him the R.M. Quigley Award for the best paper in the 2002 Canadian Geotechnical Journal. In 2004, American Society of Civil Engineers (ASCE) awarded him the Arthur Casagrande Award for his work on the residual strength of liquefied soils. The Casagrande Award was established to provide professional development opportunities for outstanding, young (under 35) practitioners, researchers, and teachers of geotechnical engineering. Dr. Olson was the first practitioner to receive this award. And, in 2012, Prof. Olson received the Walter L. Huber Civil Engineering Research Prize from ASCE.
