Research:

Dr. Wells is a structural geologist, with current research interests including: the processes of contraction and extension in the internides of mountain belts, in particular the Mesozoic Cordilleran Orogen of the western United States and; the timing and mechanisms of exhumation of mid-crustal rocks during Cenozoic extension. These studies are carried out by integrating field-structural studies with modern techniques of strain and kinematic analysis. Additionally, thermochronology is applied to structural studies to link the structural history of deformed rocks to their thermal histories, in an effort to determine the progressive deformation and kinematic trajectories within orogenic belts.
