Bio

Emeritus (Active) Professor, Geological Sciences

My students and I are using quantitative field data and principles of structural geology, combined with laboratory and computer modeling, to address fundamental questions about processes of faulting, fracturing and rock deformation. Geologic structures play important roles in attempts to utilize nature's gifts wisely and to mitigate natural hazards. Our research aims to understand how faults and fractures affect the flow of magma, groundwater, and hydrocarbons, and the crucial role fractures play in earthquake generation and volcanic eruption.

Research & Scholarship

Current Research and Scholarly Interests

Research
Our research aims to understand how faults and fractures initiate and evolve in Earth's brittle crust, how they affect the flow of molten rock, groundwater, and hydrocarbons, and the crucial role faults and fractures play in earthquake generation, folding of sedimentary strata, and volcanic eruption.We use quantitative field data and the principles of structural geology, combined with computer modeling based on continuum and fracture mechanics, to address fundamental questions about the processes of faulting, fracturing, and folding. Our understanding of the geologic structures created by these processes plays an important role in managing resource recovery and in the mitigation of natural hazards. To enhance the precision of our field data, we use the Global Positioning System (GPS) and Airborne Laser Swath Mapping (ALSM).

Teaching
I teach the undergraduate course, Fundamentals of Structural Geology and I am writing a new textbook for undergraduates called A First Course in Structural Geology. For graduate students I teach Structural Geology and Rock Mechanics with applications to solid earth geophysics, structural geology, and tectonics. We use the textbook I co-authored called Fundamentals of Structural Geology, published by Cambridge University Press. Each quarter I teach a graduate seminar on the Literature of Structural Geology and recent research developments.
