B.S. (honors), Geol. Sci., University of California, Santa Barbara, 2002

 

RESEARCH INTERESTS

 

My students and I conduct field-based and laboratory studies from microscopic to continental scales to better understand lithospheric deformation and regional tectonic processes. Current research interests include:

             Controls on orogenic structural style in continental fold-thrust belts

 

             Tectonic evolution of the northern Basin and Range

 

             Feedbacks among forearc and retroarc thrusting and arc magmatism in Cordilleran orogens

 

             Constraining the geometry and kinematics of Rodinian rifting in western Laurentia

 

             Application of low-temperature thermochronometry to constrain the timing of contractional and extensional tectonism

 

             Investigation of the basement framework of the northern Rockies
