My research interests focus on surface processes and active tectonics, and how they interact to shape and change the landscape through time. I examine the interactions between tectonic forces which drive the growth of mountain ranges and surface processes which work to erode and degrade these ranges. I am interested in how the balance between these forces controls landscape evolution and how landscapes respond to changes in tectonic and climatic forcing. My current research aims to understand the causes of spatial patterns of differential erosion between Fiordland and the Southern Alps, New Zealand. I examine tectonic forcing, erosional processes, and the erosional resistance of underlying bedrock. My research utilizes geostatistical analysis of landscapes using GIS, remote sensing, and numerical modeling, basin-averaged erosion rates derived from detrital cosmogenic radionuclides, rock strength and fracture measurements from the field and lab, and extensive field investigations of active processes and deformation. |

| My interest lies in the role and nature of an
aqueous fluid or supercritical fluid phase in the genesis and evolution of magma in subduction zone settings. Element partitioning between aqueous-fluid and solid or melt phases has received little rigourous treatment but appears to be significant. I hope to constrain fluid phase chemistry, interaction, and transport properties in a holistic approach from liberation of slab fluids during subduction to eruption in an arc setting. |

| My research interests focus on extensional tectonics, and rift related sedimentation and volcanism. Specifically, I’m interested in how sedimentation and volcanism in supra-detachment basins is distributed in space and time, both along- and across-strike, and how that relates directly to rapid slip on the basal detachment fault, development of upper plate structure and ultimately how continental lithosphere accommodates large magnitude extensional strain. Currently, I’m studying upper plate basement, sedimentary, and volcanic rocks of the Central Mojave Metamorphic Core Complex (CMMCC). Of all the Cordilleran core complexes, the CMMCC probably provides the most complete along- and across-strike exposure of hangingwall strata. Using a combination of field-based studies and detailed 40Ar/39Ar geochronology I will determine the precise rates, timing, and distribution of upper plate sedimentation, volcanism, and structural deformation parallel and perpendicular to strike of the basin. Together with constraints on footwall uplift of the core complex, determined by 40Ar/39Ar thermochronology, these data will elucidate how upper plate processes relate directly to rapid slip on the basal detachment fault. As a consequence of this research, I will be able to test conceptual models put forth to explain core complex uplift, and shed light on how continental crust responds mechanically and dynamically during large-magnitude extension. |

| Currently I am developing a numerical model
to describe some observed behavior of bedrock rivers. I am focusing on the response of tributary junctions to changes in uplift rates. I am also preparing to travel to western China where I will be investigating the growth of the Tian Shan mountain range using paleomagnetism, and other measures of deformation. |
