PhD Marco A. Lopez-Sanchez

Short bio: Marco is a postdoctoral researcher in the Dept. of Geology at University of Oviedo (Spain). He received his Ph.D. in Geology from the University of Oviedo in 2013 supervised by Sergio Llana-Fúnez. His thesis dealt with the study of a deep crustal-scale shear zone located in the hinterland of the Iberian massif. From 2013 till now, he combined jobs outside academia as Geology teacher and self-employed geology consultant with post-doctoral training in the Sergio Llana-Fúnez research group. So far, Marco has participated in four research projects.

His research interests range from different aspects of geodynamics, from microscopic to orogen-scale processes. Primary interests are rock deformation and rheology, crustal-scale shear zones, crustal strength modelling, characterization of rock microstructure using image analysis and EBSD techniques, and understanding strain localization in nature. He also has academic interests in the geological mapping and evolution of ancient orogens, the interaction between rock deformation, fluids and metamorphism, and the establishment of the absolute time at which deformation processes occur. Marco also enjoys doing statistics, scientific computing, and programming to create scientific tools.
