Author: Christoph Grützner
I studied Geophysics in Leipzig and did my PhD in Aachen. I worked as a post-doc at the Institute for Neotectonics and Natural Hazards at RWTH Aachen University, Germany. Currently I am a research associate at the University of Cambridge, working in the EwF Project on active tectonics of Central Asia. My research interests are active faults, paleoseismology, ancient earthquakes, and tectonic geomorphology.
