Dr. Karyne Ferreira dos Santos holds a Ph.D. (2021), a Master's degree (2016), and a degree in Civil Engineering (2013), emphasising sustainable materials engineering and civil construction components. She was awarded a scholarship for her Ph.D. at the University of Brasília UnB, Brazil, where she spent two years at the National Civil Engineering Laboratory—LNEC, Portugal. Her Master's in Civil Engineering was completed at COPPE, Latin America’s largest center for research and education in engineering at the Federal University of Rio de Janeiro UFRJ, Brazil. Her research focuses on special concrete, such as 3D printed concrete, self-healing concrete, high-strength concrete, fibre-reinforced concrete, and refractory concrete. Additionally, she studies different types of cement, such as those with lower CO2 emissions. She is an active member of RILEM Technical Committees, PFC (Performance requirements and testing of fresh printable cement-based materials), and 282-CCL (Calcined Clays as Supplementary Cementitious Materials) and a former member of the 261-CCF (Creep behavior in Cracked Sections of Fiber Reinforced Concrete) and SARCOS (Self-healing As prevention Repair of Concrete Structures). Also, she was a Substitute Professor at UFRJ, Brazil.

Samuel Santos earned his Bachelor’s (2011) and Master’s (2013) degrees in Chemical Engineering from the Instituto Superior de Engenharia de Lisboa (ISEL) at Lisbon Polytechnic. His Master’s thesis centered on the use of amine solutions for CO₂ capture and release in flue gases, leading to both a published scientific article and a book. Between 2013 and 2015, Samuel contributed to the ACoPP project (Advanced Near Zero Emission Coal-Fired Power Plant) funded by the EU. In 2015, he became a Research Fellow in the ECOFOULESS project, where he worked on anti-fouling solutions to control biofouling in aquaculture. He continued this research trajectory in the GREENFUEL project, where he remained until early 2017. From 2017 to 2024, Samuel pursued a PhD in Chemical Engineering through the CATSUS Doctoral Program at CERENA, Instituto Superior Técnico. His dissertation, "Development of Nanocatalysts from Calcium Waste Materials in Biodiesel Production," was supervised by Professors João Gomes (ISEL-CERENA), Jaime Puna (ISEL-CERENA), Rosa Quinta-Ferreira (FCT-Universidade de Coimbra), and João Bordado (IST-CERENA). Samuel is now a Researcher at CoLAB C5Lab – Sustainable Construction Materials Association, where he is currently developing approaches for the decarbonisation of the cement industry.

Dr. Manuel Vieira received a degree in Civil Engineering and graduated from the High Technical Institute (IST), Technical University of Lisbon, in 1992. He received both an M.S. degree in Construction on the durability of lightweight concrete aggregates and a PhD. degree in Civil Engineering on the rheology of the fresh state of self-compacting concrete. He is a Researcher at the Cementitious Materials Division of the National Laboratory of Civil Engineering, dealing with the development, optimisation, characterisation, and regulation of concrete and its constituents.

Dr. António Santos Silva is a Principal Researcher of Materials Department at the National Laboratory for Civil Engineering (LNEC). He has a degree in Technological Chemistry from the Sciences Faculty of Lisbon University (1990) and a PhD in Civil Engineering from the School of Engineering of the University of Minho (2005). He is the Coordinator of the Laboratory for Mineralogical and Microstructural Characterization of Materials (U3M) at LNEC. He coordinated and participated in national and international research projects. Current highlights include his participation in H2020 project “ATRIUM—Advancing FronTier Research In the Arts and hUManities”, in the Collaborative Laboratory C5Lab—Sustainable Construction Materials Association, and in the Research Infrastructure ERIHS.pt—European Research Infrastructure for Heritage Science Portuguese Platform. His research areas focus on chemistry and materials engineering, in particular material durability and performance. He conducts studies on the diagnosis and prognosis of expansive chemical reactions in concrete, including mitigation and repair, and also on the characterisation of historic construction materials, conservation solutions, and the implementation of digital tools for the dissemination and preservation of architectural and archaeological heritage. He is member of RILEM Commissions and of European groups for preparing Guides for European Technical Approvals.

Dr. Cinthia Maia Pederneiras has been working in sustainability in the construction sector for over 10 years. She has a Ph.D. in Civil Engineering from IST, University of Lisbon. Currently, she is working as a project manager at c5Lab (Clinker × Cement × Concrete × Construction x Carbonation), investigating the carbon capture and storage (CCS) of cementitious materials and the development of new materials.
