Alex Copley

University Lecturer, Department of Earth Sciences, University of Cambridge

I am an Earth Scientist working in the University of Cambridge, studying active tectonics from the scale of individual fault systems to large mountain ranges. My work spans observations of active deformation (using seismology, InSAR, field and remote sensing observations of geomorphology, etc.), and numerical modelling to understand the underlying forces at work. Areas of particular interest include the active deformation of the continents and the rheology of the lithosphere.
