Sónia Simões is an 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 the University of Porto. Later, she received a Post-Doc grant in Materials Science and Engineering. She is currently a member of INEGI (Institute of Science and Innovation in Mechanical and Industrial Engineering) of the Materials and Manufacturing Processes research group of LAETA (Associate Laboratory of Energy, Transports, and Aeronautics). Sónia Simões has participated in some Materials Science and Engineering projects funded by the 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 has accumulated valuable experience in advanced transmission electron microscopy, which has been an extremely important tool in developing research work.
