The Himalayas

Our research program is defining how and why deformation is actively accumulating in the Himalayas using a combination of methods in field geology, river longitudinal profile analysis, low temperature thermochronology and erosion rate estimation. We are particularly focused on how the Himalaya are potentially seismically segmented along strike and are interested in the forcings that might drive this segmentation.


Central America

Using interactions between geomorphology and tectonics, we are investigating subduction zone processes from the trench to back arc, evaluating the timing of arc cessation and isthmus closure, and exploring how subduction zone properties affect upper plate deformation on a variety of spatial and temporal scales.


Cascadia 

With colleagues from Western Washington University and Boston University, we are exploring the kinematics and slip history of crustal faults, and how and why permanent strain is accumulated within the upper plate of the Cascadia subduction zone on southern Vancouver Island.  This work is primarily based on detailed structural and geomorphic field work targeted by bare earth lidar data, and is further informed by paleoseismic trenching. Our research is also placing constrains on the seismic hazard that shallow crustal faults may present to the southern Vancouver Island region.
