Computational Material Science. University of Oviedo.

Specialized in the simulation of structural, magnetic and transport properties of advanced materials by means of electronic structure calculations that use ab-initio codes based on DFT (Density Functional Theory). Our input is relevant to the computational characterization and design of highly demanding materials with engineering applications by means of multiscale modelling techniques.
