Info:

Bachelor’s degree in Physics by University of Campinas (1986), Master’s degree in Physics by University of Campinas (1991) and Doctor’s degree in Physics by University of Sao Paulo (1999). In 2011-2012 attended a post-doctoral internship at Max-Planck-Institut für Eisenforschung (MPIE) in Düsseldorf, Germany. Since 2006 is assistant professor of the Department of Materials Engineering of the Lorena School of Engineering of University of Sao Paulo (EEL-USP). Worked in the research area of superconductivity, mainly on Cu-Nb metal composites and Nb3Sn based multifilamentary wires. Currently works on the relationship of microstructure and magnetic properties of stainless, duplex, and Mn-based steels.
