Luís Guerra Rosa (born in 1954) currently carries out his activities at IDMEC—Instituto de Engenharia Mecânica in Lisbon. IDMEC is part of the Portuguese Associated Laboratory for Energy, Transports and Aeronautics (LAETA). LG Rosa began his career as a lecturer and researcher in 1977 at the Instituto Superior Técnico (Lisbon) after graduating in Metallurgical Engineering. In 1986, he obtained a Ph.D. in Mechanical Engineering with a dissertation on the nucleation and propagation of cracks in steels when subjected to cyclic loading (fatigue) using the concepts of fracture mechanics. In 1988, he created his own research group and began to give preference to studies on ceramic and composite materials. In 2004, he obtained the academic title of Agregado in Materials Engineering from the University of Lisbon. Prof. Dr. Rosa has been devoting his time to problems involving structural and technological characterization of materials at different stages of their elaboration to understand their behavior, to compare their properties to references and specifications, and to evaluate their performances in condition-simulating applications. During the last 20 years, he has been quite active in two major topics: 1) materials processing using solar energy; 2) ornamental and engineered stones (characterization and processing). The links and joint projects with foreign groups reached a very good level of collaboration, with publications and research contracts showing interdisciplinarity.
