Sónia Simões (female) is Assistant Professor at the Department of Metallurgical and Materials Engineering, of University of Porto. She graduated in 2006 and completed a PhD degree in 2011, in Metallurgical and Materials Engineering by the Faculty of Engineering of University of Porto. Later, she received a Post-Doc grant in Materials Science and Engineering. Sónia Simões has participated in some projects in the area of Materials Science and Engineering funded by Portuguese Science Foundation and European Commission. During the last years her research mainly addressed the study of microstructural and mechanical characterization of nanomaterials, thin films, multilayers, joining interfaces, carbon nanotubes and nanocomposites. In particular, she is interested in understanding the relationships between the microstructure and the properties of materials and the fundamental underlying mechanisms of structural and property changes induced by some microstructure features (grain growth, formation of new phases…). Since 2006, she accumulated valuable experience in transmission electron microscopy, which has been an extremely important tool in the development of the research work.
