My research focuses on understanding the processes and time-scales over which brittle faults grow, interact and evolve. This includes studying: 1) the structure of propagating fault tips, 2) the pattern of displacement accumulation on faults, 3) how fault displacements scale with fault length, and 4) the temporal evolution of faults via basin analysis and geomorphic studies.
Geographically, much of my work on fault evolution and tectonic landscape development has been within the Eastern California shear zone and in the northern Basin & Range. I also have projects in south Louisiana looking at recently active "growth" fault systems, including the contribution of these large fault systems to coastal land loss.
Many of the problems I am interested in are applicable to other terrestrial planets. One of my current interests is in dike-induced graben formation on Mars. These systems preserve information on magmatic rifting that is often erased by erosion and deposition in Earth's rift systems.
Prior to coming to Tulane, I worked as a Research Associate at the University of Edinburgh, Scotland. While in Edinburgh, I worked mainly on the evolution of Late Jurassic normal faults, in the northern North Sea, using 3D seismic data. I have a continuing interest in utilizing 3D subsurface data in both teaching and research.
