I am a field-oriented geologist that employs tools of structural geology, petrology and thermochronology to investigate rates and mechanisms of tectonic processes. My current collaborations include the study of the strike-slip history of the East Gobi Fault Zone in southeastern Mongolia where we are evaluating the timing and kinematics of intraplate deformation and basin formation in southeastern Mongolia. The results of this research are relevant to testing end-member models of continental block extrusion and continuum shortening during Asia’s history of collisions from Mesozoic–Recent. I am also active in a collaborative research project in eastern Papua New Guinea where we are evaluating the exhumation of world’s youngest known ultrahigh-pressure terrane in the context of the larger scale Australian–Pacific plate boundary evolution.
I teach courses in geochronology, petrology, microstructural analysis and tectonics. In the classroom and in practice, my students and I integrate analytical data with observations made at microscopic to continental scales to try and understand how rocks and regions evolve in space and time and the tectonic processes that shape them.
