is Professor of Geological Engineering at the University of Idaho, where he teaches and conducts research in applied rock engineering, probabilistic methods in geotechnical engineering, slope stabilization, and geological engineering design. He has over 20 years of experience in geotechnical consulting, including projects for mining applications, reinforced soil structures, and slope stability investigations. He also has taught workshops on these topics over the last 15 years in the western U.S., in Canada, and in SE Asia (Malaysia and Singapore). His major interests are in rock slope stabilization, segmental retaining walls, risk analysis, and erosion control for steep slopes.
