My research and teaching interests are in the general area of structural geology applied to solving problems related to the physical and chemical evolution of the Earth’s crust and upper mantle. In my research, I use a combination of active testing of how changing variables such as temperature and strain rate affects the microstructures that develop due to specific deformation mechanisms and observational analysis of naturally deformed rocks to constrain the conditions that produce these same microstructures in nature. Understanding these grain-scale processes contributes to our understanding of larger scale processes and controls on plate tectonics.
I am currently working on an NSF-funded experimental study of the effects of magnesite on the initiation of deep focus earthquakes in subduction zones in collaboration with Drs. Andreas Kronenberg (Texas A&M University), Paul Raterron (Brown University) and Reid Cooper (Brown University).
The Rock deformation laboratory at the University of Akron has a wide variety of tools for preparing cores of rock for experiments and two apparatus for performing experiments on rocks. The Griggs-type rock deformation apparatus is capable of deforming rocks at pressures up to 2000 MPa and temperatures up to 1400°C. The Griggs apparatus has been used in experimental studies performed on quartz single crystals (Edward Poston), quartz polycrystals (Albert Barbery, Danielle Anderson, Casey Braccia), gneisses (Rebeccah DiPuccio) and magnesite (Joseph Millard and Caleb McDaniel). The other apparatus, a Forney concrete testing machine with Hoek-type pressure vessel, is capable of deforming rocks at pressures up to 70 MPa and room temperature. This apparatus was used by Robert McGinnis to determine the mechanical properties of limestones and sandstones from Kentucky used to construct a model of cave formation.
