Dr. S. Fernández earned his BSc and MSc with honors at the University of Girona (Spain), where he began research in computational and experimental catalysis for H2 production under Prof. Julio Lloret-Fillol and Dr. Josep M. Luis. He then obtained a competitive FPU fellowship from the Spanish Ministry of Universities to pursue his PhD at the Institute of Chemical Research of Catalonia (ICIQ), focusing on photo- and electrocatalytic CO2 reduction to fuels. In 2022, he joined Prof. Alex Miller’s group at UNC-Chapel Hill (United States), where he developed an electrochemical–thermal cascade for CO2-to-methanol conversion and served as a thrust coordinator in the U.S. DOE Solar Fuels Hub (CHASE). Supported by an International Postdoctoral Fellowship from the Ramón Areces Foundation, he expanded his research in the U.S., working on compartmentalization strategies for acidic CO2 electroreduction. During his career, he has completed research short-stays at the University of Paris and Yale University, and has participated in synchrotron projects at Diamond Light Source (UK) and Soleil (France). Most recently, Dr. Fernández was awarded a Juan de la Cierva Fellowship (Spanish Ministry of Science and Innovation) to return to the University of Girona (IQCC-UdG), where he is currently developing electrochemical strategies for C–H functionalization in the group of Prof. Miquel Costas.
