Our group studies the geometric, kinematic and erosional evolution of mountain belts, particularly in the Himalaya, Andes and Appalachians. Current research activities focus on linking the geometry and kinematics of mapped structures to thermochronometer cooling ages to look at the interplay between tectonics and erosion on exhumation patterns and morphology of mountain ranges. Research projects start with structurally based field studies, typically through the creation of new geologic maps at previously unpublished scales or resolutions. Using this high resolution geological mapping as a foundation, the projects expand to include the creation and sequential restoration of geologic cross sections (providing kinematics) as well as new mineral cooling ages to determine the distribution, magnitude and rate of deformation. Details of current projects available here.

GEOL 1100 Structural Geology
An introduction to basic geologic structures, including the development of folds, faults, joints, and foliation. The use of these structures in geologic mapping, and their interpretation in terms of structural geometry will be covered. The concepts of stress and strain will also be introduced. These basic concepts will be integrated into a study of the evolution of mountain belts.
Offered every spring term. Lecture 3 hours; laboratory 2 hours.
GEOL 2110 Plate Tectonics
Historical background of the concept of plate tectonics. Geophysical evidence for reconstructing the motions of continental and oceanic areas. Plate tectonic processes and characteristics of plate boundaries. Dynamics -- the nature of the driving forces. Geosynclines, orogenic belts and crustal evolution will be examined with regard to plate tectonic theory. Types of plate boundaries (divergent and convergent zones, transform faults) will be studied and compared to existing geotectonic features.
Offered every other year. Lecture, 3 hours.
GEOL 2120 Basin Analyses
The integrated study of sedimentary basins as geodynamic entities, including tectonic environment, geologic history and associated strength of the lithosphere, rock weathering and erosion, and sediment transport. The class will give students a background in driving mechanisms for basin formation and subsidence, sedimentary record preservation and alteration, sedimentary geometry, facies and petrology and provide a basic understanding of the continuum mechanics equations that approximate basin formation.
Offered every other year. Lecture, 3 hours.
GEOL 3908 Topics in Geology
This course allows the flexibility of exploring, in depth, a new topic in geology each time it is taught. Past topics have included:
Appalachian Geology -- This seminar course is designed to cover all things Appalachian; tectonic setting, paleoclimate record, thermal history, sedimentology, stratigraphy, depositional environments, structural geology (regional, outcrop, to micro scale), geomorphology (regional and local scales), geochemical signatures, etc.,
Fold-thrust belts and sedimentary basins -- Paired fold-thrust belts/foreland basin systems produce the largest mountains in the world as well as host a large percentage of the world’s oil and gas reserves. Understanding the geometry and kinematics of this paired system is a requirement for understanding how these mountain systems and the reservoirs of natural resources form. Reading assignments and lectures will cover the origins of fold-thrust belts, thrust belt geometry, mechanics and kinematics as well as learning the technique of balancing cross sections through a fold-thrust belt.
