Curriculum Vitae

Cecilia Isabel Alves Ventura Santos

Cecília Santos is an Invited Assistant Researcher at the Coimbra Chemistry Centre (CQC-IMS), specializing in the Physical Chemistry of Non-Ideal Transport. Her career is defined by the development of unique experimental infrastructures and the study of molecular mobility in extreme environments, spanning from microgravity research on the International Space Station to industrial resource recovery. She obtained a double PhD in Chemistry (2012) from the University of Coimbra (Portugal) and Universidad de Alcalá (Spain), awarded with the "Prémio Extraordinário de Doctorado". Her doctoral work pioneered the construction of European experimental setups for multicomponent transport properties. In 2017, she earned an Executive MBA, integrating strategic project management and technology transfer expertise into her scientific leadership. Her postdoctoral trajectory includes a high-impact period at Université Libre de Bruxelles (2012–2013) within the ESA/DCMIX topical team. She designed experiments on heat and mass transfer for both ground and microgravity conditions (International Space Station), followed by an international FCT fellowship focused on petrochemical transport models. Since 2019, she has managed the Laboratory of Supercritical Diffusion (CQC-IMS), where she established a unique high-pressure FTIR-Taylor Dispersion platform—a cutting-edge infrastructure for measuring diffusion in dense fluids. As a Principal Investigator (PI), she led the KIDIMIX project (2018–2022), investigating CO2 geological storage mechanisms. Her current research focuses on the application of supercritical fluids to environmental challenges. In 2023, she launched the NeWLOife project, which resulted in a international patent application for a sustainable methodology for waste lubricant oil regeneration and an award at Acelera@UC (Honourable Mention, 2025), as well as catalyzed several competitive fundings e.g. an FCT exploratory project (Luboregen,2023), direct industrial support industry (Sogilub, NeWLOife II, 2025), and proof of concept initiatives (LIPIDX and BioXylSafe, INOVC+, 2025). She currently leads a consortium with SISAV/EGEO (ReneWOiL, CCDRC, 2026), successfully bridging fundamental thermodynamics with the Circular Economy. Cecília is an active educator at the UC Department of Chemistry and a dedicated mentor, supervising numerous MSc and PhD students. Her international prestige is reflected in her role as an Expert Evaluator for European funding agencies (Belgium, REA-EU) and a referee for top-tier journals. She is also committed to science communication, authoring a science manual for children and leading the FCTUC-Bissaya Barreto protocol for early-childhood science education.
