PhD Marco A. Lopez-Sanchez

Short bio: Marco is a postdoctoral researcher at Géosciences Montpellier - CNRS in France. He holds a PhD in Geology from the University of Oviedo in Spain. In the past, he combined jobs outside the academy as a Geology teacher and freelance geologist with postdoctoral training in the research group of Sergio Llana-Fúnez located in Oviedo. Since the beginning of 2018, he is working with Andréa Tommasi in the Manteau et Interfaces research group in Montpellier, where his research focuses on characterisation of deformation and annealing processes at the microscale using in-situ monitoring.

Marco research interests include different aspects of geodynamics, from microscopic to orogen-scale processes. His primary interests include rock deformation and rheology, crustal-scale shear zones, crustal strength modelling, characterization of rock microstructure using image analysis and EBSD, and understanding strain localization in nature. Others are 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. I also enjoy programming for data analysis and the creation of tools for doing science.
