Numerical modelling and simulation of mechanical systems and structure has been recognised as an invaluable tool for several engineering fields, namely Mechanical and Civil, specially due to the rapidly growing computational power over the last decades. Nowadays, progressively smaller details of the bodies, such as roughness and microstructure can be embedded in numerical simulations within multi-scale numerical strategies, which renders such topic extremely attractive for research nowadays.I work as a research and teaching assistant at the Computationally Multi-Scale Modeling of Solids and Structures group (CM2S) at the Faculty of Engineering of the University of Porto. In CM2S, we develop advanced and novel numerical strategies for modeling the mechanical behaviour of materials at distinct coupled and uncoupled length scales. My areas of interest are computational contact mechanics within Finite Element Method frameworks and multiscale strategies for embedding roughness at different length scales. Our research work rely on competence in code design, programming, classical mechanics of deformable bodies, several topics of mathematics, besides other highly important soft skills such as tenacity, teamwork and critical thinking.In the pedagogic scope, on which I find considerable personal and professional fulfilment, I like to transmit my passion for the subjects I teach, in particular, those related with general mechanics and strength of materials. Moreover, I try to promote a logical and structured mindset for problem solving, and also to explore different perspectives of the problems, so that students can find the easiest way to absorb different concepts, without hard-coding their brains in a rigid way.
