My research interests are in structural geology and focus on understanding the origin, evolution, and dynamics of seismicity preserved in exhumed basement faults. This is primarily accomplished through integrated field and microstructural study of the products of frictional melting and progressive wear generated by earthquake rupture and interseismic creep. Related interests include coupled basement-cover deformation in multiply reactivated fault zones and the nature of incompetence. Current field research focuses on Proterozoic shear zones and Paleozoic–Laramide faults in the Colorado Rockies, and pseudotachylytes rooted in the Paleoproterozoic Nagssugtoquidian orogen in SW Greenland.
