Teaching and Research Statement:

Thoughtful application of scientific approaches has been the cornerstone of my teaching and research. I consider myself a diagnostic, “multiple working hypothesis” scientist and seek to instill an active scientific consciousness in my students. This perspective has allowed us to contribute to numerous debates in structural geology and tectonics by integrating observations from multiple perspectives.

I spent 26 years teaching structural geology and tectonics at Colorado State University in a full time faculty position. My CSU students and I enjoyed integrating input from multiple disciplines, including structural, geophysical and geochemical data, and at diverse scales, from micro-scale mineral equilibria, geochronology and strain analysis to regional scale fold modeling and tectonics. Field studies have been the basis for much of our research as the real world has provided us with our best inspirations. Our largely field-generated hypotheses are typically tested by subsurface data, geochemical data, and 3D kinematic restorations.

Recent collaborative research projects funded by petroleum industry sponsors have created a very productive synergism of academic theory and industry data. An early retirement from CSU and an adjunct position at the University of Wyoming have allowed me to maintain my academic graduate and research programs while allowing more interaction with petroleum and other geologic industries. The already strong critical mass of structural and tectonic expertise at the University of Wyoming will allow me to continue my graduate program and strengthen my bridge between academia and industry.
