All of my research has evolved around displacements of materials and how they can be predicted or measured based on field data. In earlier days, I investigated the emplacement mechanisms for the northeastern sector of the Idaho batholith and how that emplacement affected the tectonic evolution of west-central Montana. This study involved field mapping in beautiful and rugged terrane, chemical and petrographic analyses, statistical structural analysis, and radiometric dating using U-Pb and Rb-Sr techniques. Funding came from three NSF Grants and two WMU Faculty Grants. I also studied for several years the effects of Precambrian basement-rock compositions and fabrics on the development of Mesozoic/Cenozoic, Rocky Mountain foreland folds. This study involved largely field investigations at a number of locations between Montana and New Mexico. Funding came from two NSF Grants.

Geotechnical Analysis

Most recently, I am applying techniques of structural analysis and rock/soil mechanics to landslide problems. Current projects involve the application of new measuring and geometric reconstruction techniques, strength analysis of rocks and soil layers, and computer simulations of landslides and their structural evolution. Ongoing funding is from grants provided by the U.S. Army Research Office and the U.S. Army Corps of Engineers.
