I am interested in global tectonics and links between deep and surface processes.
Currently, I am working on shear wave imaging of the subduction zone in southern Peru using both earthquake-generated and ambient noise Rayleigh waves. Here, the subducting Nazca plate starts to subduct steeply, but bends at ~90 km depth and remains flat for several hundred kilometers. Focusing on the Peruvian flat slab, I am trying to understand how flat slabs form, what controls their inboard and along-strike extent, and how this change in slab geometry relates to geologic features at the surface (inboard migration of arc volcanism, volcanism cessation, crustal deformation removed far from the subducting margin).
