Our group studies the geometric, kinematic and erosional evolution of mountain belts, particularly in the Himalaya, Andes and Appalachians. 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.
