Research
My research includes remote and field-based work in structural geology and neotectonics to investigate the timing and development of slip partitioning in actively deforming regions. My work utilizes surface and bedrock mapping to document kinematics and strain markers offset by active structures, and geochronology to quantify deformation rates of deformation. I employ a wide range of expertise including surface mapping, subsurface visualization, geomorphology, surface processes, and isotope geochemistry.
Western Nepal
My collaborators and I are investigating active structures in the High Himalaya of West Nepal thought to be the result of strain partitioning that segments the Himalayan thrust wedge. My work documents the geomorphic signature of right-slip and normal-slip structures in order to estimate Quaternary slip rates, fault geometries, and kinematics.

Walker Lane Belt
I have worked on structural and neotectonic studies that utilize volcanic and geomorphic strain markers to estimate fault initiation ages, kinematics, and slip rates on right-lateral structures in the Walker Lane Belt.
