The western escarpment creates an impressive landscape in the Guadalupe Mountains of Texas and New Mexico. My students and I are looking at the evolution of drainage basins, knickpoints, and the uplift history in this region.

Ongoing Projects
Evaluating apatite quality for potential (U-Th)/He thermochronometry.
Evaluating spatial patterns of faulting and erosion using digital elevation models, Google Earth, and drainage basin characteristics.
