About Vern

Dr. Schaefer’s research has covered a wide variety of geotechnical and geoenvironmental engineering areas, predominately in landslides and slope stability, ground improvement, earth retention systems, engineering behavior of over-consolidated clays and clay shales, glacial till permeability, water and contaminant migration in fractured soils, and geotechnical aspects of pavement systems. He has developed 44 projects, generating over $9 million in research from the National Science FoundationFederal Highway Administration, United States Geological Survey, United States Environmental Protection Agency, and numerous state agencies. Dr. Schaefer was the primary investigator for the SHRP2 R02 project Geotechnical Solutions for Soil Improvement, Rapid Embankment Construction, and Stabilization of the Pavement Working Platform from 2007 to 2013. This $3,700,000 project was aimed at improving access to geotechnical engineering technologies for transportation infrastructure and developed the GeoTechTools web-based information and guidance system, which is currently being deployed to state DOTs across the country.
