Cecilia Santos concluded her BSc Degree (4 years) in Chemistry at the University of Coimbra (UC) in 2006. She obtained her double Ph.D. degree in Chemistry in 2012 by the University of Coimbra (Portugal) and Universidad de Alcalá (Spain) (supported by SFRH/BD/45669/2008). Her doctoral work was interdisciplinary research on thermodynamic and transport properties of drug release systems. She pioneered the construction of an experimental setup for the measurement of transport properties for multicomponent systems in Europe, being invited as visiting scholar to other international labs to consult on similar setups. She was awarded a "Prémio Extraordinário de Doctorado" for her doctoral thesis, highlighting her expertise in transport phenomena and pharmaceutical technology areas. She was a lecturer at UAH Department of Physical Chemistry and supervised BSc and MSs students. Additionally, she served as the communications secretary for the XIX Meeting of the Iberoamerican Electrochemical Society. Postdoc activity was developed as contracted researcher in Université Libre de Bruxelles (2012-2013). She worked in DCMIX topical team (Belgian PRODEX and ESA), elaborating experiments on heat and mass transfer in ground and in microgravity conditions in the International Space Station. She returned to UC in 2014 as a postdoc fellow to study the multicomponent transport in petrochemical models for carbon dioxide underground storage (supported by SFRH/BPD/92851/2013). She earned her MBA in 2017, which helped her develop project management, innovation, I+D management, and knowledge transfer skills. She has been managing the Laboratory of Supercritical Diffusion at Coimbra Chemistry Centre since 2019 when she was engaged as a Researcher (DL/57). She leaded, as principal investigator, the project Kinetics of Molecular and Thermal Diffusion for Model CO2 mixtures near Critical Point- supported by FEDER (2018-2022). KIDIMIX sought to better understand and explain the mechanisms involved in carbon dioxide geological storage and to provide information for the development of safer and more efficient storage technologies. She has created a cutting-edge experimental apparatus for the measurement of diffusion in supercritical fluids. Simultaneously, she has been interested in investigating the applications of supercritical CO2 for green and sustainable chemical processes, namely in pharmaceutical and industrial technologies. Recently (2023) she leads NeWLOife a project in collaboration with industrial partner Sogilub, aiming the development of a more sustainable regeneration methodology for waste lubricant oils using supercritical carbon dioxide for their circular economy. Her area of scientific activity is Chemistry, with main interest in the research areas of medicinal and physical chemistry, thermodynamics, and transport phenomena. Her research topics include thermodynamics and transport properties of multicomponent systems, hydrocarbon mixtures, molecular and thermal diffusion and supercritical fluids. More recently she has been interested in understanding applications of supercritical fluids in green chemical technologies and how they can be applied to solve environmental challenges, as to the development of more sustainable processes. She has h-index 15 (Scopus) and 14 in WoS (Web of Science), with of over 40 international peer-reviewed publications (including high impact journals like J. Chem. Physics, J. Mol. Liquids, Molecules, etc.) also frequently presents at scientific conferences. She has over 10 book chapters, edited 1 book and is the invited editor (2023) for a special issue in the topic of Drug Delivery. She has been lecturing at the Department of Chemistry of UC and supervising undergraduate and graduate students. She is also acting as evaluator for funding agencies (Belgium). She is often invited to the jury of MSc and BSc theses, acts as external evaluator for European PhD thesis and as referee of various prestigious journals.
