My research aims to understand deformation in the lithosphere over a range of levels, conditions, and spatial scales, with a particular focus on processes that affect its dynamic evolution, including: the growth and collapse of orogenic systems; feedbacks between deformation and melt migration in the mid-crust through upper mantle; and mechanisms of strain localization and rheological weakening. Understanding these processes across a range of spatial scales and tectonic settings requires expertise in a variety of analytical methods, which I believe are best complemented by research fundamentally rooted in comprehensive field-based investigation.
As a quantitative, field-oriented structural geologist, I employ a multi-disciplinary approach to research that draws upon a variety of analytical techniques applicable to tectonic studies, including: detailed field-based mapping and structural analysis, crystallographic textural analysis using electron backscatter diffraction (EBSD), geochronology and thermochronology studies, and petrologic investigations. These research interests have led to student research opportunities on diverse topics in regions of the Earth spanning from Antarctica to New England.
I am always looking for new students interested in Structural Geology and Tectonics studies, so for more information about current opportunities please see my personal website on the pages linked below.
