My research career has been focused on the study of magnetic and transport properties of functional complex oxides. The main objective has been to understand the interrelationship between microstructural features and the observed functional properties.

I got my PhD degree at the University of Santiago de Compostela in 1990 with a work about the thermodynamic fluctuations in high temperature copper oxide superconductors. During these years I have been also involved in the study of the influence of structural inhomogeneities into the magnetotransport properties of single crystal superconductors. In 1996 I have joined the Laboratoire de Physique des Solides at University of Orsay-France to study the influence of columnar defects created by heavy-ion irradiation in the vortex pinning properties of superconducting thin films. Vortex matter in high temperature superconductors has relevant interest from a fundamental point of view as a model system with competing interactions but also from an applied point of view to increase the current carrying capabilities of superconductors. In 2002 I have joined the Instituto de Ciencia de Materiales de Barcelona- ICMAB-CSIC to study the growth of superconducting wires from chemical methods. I have dedicated an intense effort to thin film preparation and characterization. My work has allowed to demonstrate the capabilities of chemical methods to prepare low cost epitaxial thin films with improved properties. We have study the mechanism controlling nucleation and growth of thin films and we have developed novel approaches to improve their vortex pinning properties.

Since 2007 I am deeply involved in studying new routes to prepare nanostructures in oxide thin films. Nowadays I concentrate my efforts in investigating the interplay between preparation and growth of nanostructured materials and their physical properties (as vortex pinning capabilities, magnetoresistance response, …). In particular I am interested in the role of epitaxial strain relaxation mechanisms in the formation of long-range ordered nanostructured and its influence on the magnetotransport properties of oxide thin films.
