He graduated in Theoretical Physics (1990) and obtained his Ph. D. in Physics (2002) at the UB after stays at the City University of NY (E. Chudnovsky) and at the University of British Columbia in Vancouver (P.C.E. Stamp) where he gained expertise in theoretical models of magnetism. He has been invited professor at Univ. Antioquia (Colombia) and Univ. South Florida (USA). His research have focused on theoretical and phenomenological models of magnetic materials, always working in close contact to experimentalists in the field. Using several simulation techniques ranging from Monte Carlo to micromagnetics, he has contributed to the study of finite-size, surface effects, dipolar interactions and exchange bias mainly in nanoparticle systems. He has authored several highly cited articles and book chapters on these subjects. His more recent research lines include curvilinear magnetism, dipolar nanotubes and magnetic hyperthermia.
