Curriculum Vitae


Research Overview

  • Field-based structural studies aimed at understanding the tectonic evolution of mountain belts
  • Finite strain and strain history analysis aimed at defining deformational patterns and kinematics of structures at all scales
  • Microstructural and textural studies to determine grain-scale deformation mechanisms in rocks and their implications for large-scale mechanics of deformation
  • Geometrical, theoretical and mathematical modeling studies to place constraints on kinematics and mechanics of deformation
  • Current research is focused on understanding the role of fluids and fluid flow in the evolution of fold-thrust belts through the use  of various structural and geochemical tools
