Enrique Gomez-Rivas Structural Geology |
CV Enrique Gomez-Rivas is a postdoctoral researcher at the Institute for Geosciences, Eberhard Karls University Tübingen since 2010. He studied Geology at the universities of Zaragoza, Oxford Brookes and Salamanca and then he did a PhD in structural geology at the University Autonoma of Barcelona (graduated 2008).
