Research Interests
I study how faults deform the Earth and lead to the uplift of mountains, as well as all the surface processes that occur in the million year interim. My research spans the spatial scale of centimeter-scale displacement of faults in trenches, to several kilometers of accumulated mountain topography across active plate boundaries. Likewise, I am interested in processes that occur over the timescale of a single earthquake to many millions of years. My work involves a broad range of survey, mapping, geochronology, and modelling techniques to quantify rates and styles of faulting. I have worked in the Basin and Range of the western USA, throughout New Zealand, and the Caucasus of Georgia.
