My research is concerned with the mechanics of fault and fracture development in the elastic-brittle part of the lithosphere and includes studies of continental rifts as well as mid-ocean ridges. In my work I use a combination of numerical modelling and field data collection. I am particularly interested in the rates of fault growth and systematic variations in space and time due to fault interaction, and the implications of rate variations for seismic hazard assessment, geomorphic processes (especially river incision) and sedimentation in active tectonic settings. At present I am actively working on various aspects of tectonic geomorphology in the Italian Appenines and mainland Greece. I am also currently involved in a project to use cosmogenically induced 36Cl concentrations to determine exposure ages along active normal faults in central Italy.
