My current research focuses on brittle deformation within the lower plate of metamorphic core complexes. I am using a combination of structural analysis and apatite (U-Th)/He dating to determine the fault-slip history along low-angle normal faults (LANFs). The Bullfrog Hills and Bare Mountain in westernmost Nevada expose several LANF splays that have exhumed Proterozoic to Devonian rocks during southern Walker Lane transtensional deformation. The cooling history of detachment splays has important implications for the significance of footwall incisement and the accuracy of thermochronometrically determined fault-slip rates.
Previous research has involved the structural evolution of the western Chugach Mountains and Prince William Sound in southern Alaska with an emphasis on flat-slab subduction processes and resulting upper-plate deformation.
Other areas of interest include:
Interplay between climate and tectonics, specifically the effects of Cenozoic glaciation on orogenesis
Contractional and extensional structures in strike-slip regimes
Surface exposure dating, TCN and OSL applied to quantification of fault-slip and surface uplift
Tectonic geomorphology of mountain belts and active structures

GeoFORCE, a K-12 outreach program of the Jackson School, is designed to increase the number of students pursuing STEM degrees in college and moving into the future high-tech workforce. Targets rural areas of southwest Texas and inner-city Houston that have historically generated a very low percentage of students who pursue college degrees and an even lower percentage of students who pursue degrees in math or science. These target areas have a high percentage of minority students, thus providing an opportunity for GeoFORCE to increase minority participation in science and math. Present students with opportunities to experience the excitement of science outside the classroom through spectacular summer field trips each year of the four years they are involved in the program.
