Overview
My research focuses on the kinematic evolution of
mountain belts. My interests range from evaluating the sequential accumulation
of strain in fold and thrust belts that may eventually produce wide (350-350
km), high elevation plateaus to the kinematics and dynamics of diffuse
continental extension. Research projects start with structurally
based field studies, typically through the creation of new geologic maps at
previously unpublished scales or resolutions. Using this high resolution
geological mapping as a foundation, the projects expand to include the creation
and sequential restoration of geologic cross sections (providing kinematics) as
well as new mineral cooling ages to determine the distribution, magnitude and
rate of deformation. Current projects I am working on in
conjunction with colleagues and students are: 1) Integrating and calculating
rates of shortening across an orogen, in the Himalayas and the Andes.
2) The interaction between erosion and deformation in
fold-thrust belts in Bolivia, Peru and Bhutan. 3) Documenting the
similarities and differences between periods of deformation, exhumation and elevation
in Bolivia and Timor.
Past
projects I have worked on include the kinematics of the Arabia/Eurasia
collision zone, evaluating both the development of the Zagros fold-thrust belt
as well as the causes of plate motion before and after collision, and tectonic
reconstructions of the North America-Pacific plate boundary over the last 36 Myr.
