Inês S. Fernandes is a PhD student fellow in chemical and materials engineering whose work focuses on modelling and optimization of electrochemical systems for CO2 conversion into solar fuels. She completed an Integrated Master’s in Chemical and Biochemical Engineering at NOVA School of Science and Technology in 2021, with a thesis on modelling porous cathodes for electrochemical CO2 reduction, and is currently pursuing a PhD in Nanotechnologies and Nanosciences at the same institution, funded by an individual FCT doctoral fellowship (FCT, I.P., ref. 2025.02777.BDANA). Her research combines multiphysics and computational modelling of porous electrodes with the design of high-performance electrochemical reactors and photovoltaic–electrochemical (PV–EC) architectures, targeting CO2-to-syngas conversion and the energetic optimization of solar-to-fuel efficiency. She is first author of 2 Q1 journal articles on modelling of electrochemical CO2 reduction and porous cathodes, and has delivered 6 conference contributions, including oral presentations at international meetings on electrochemistry, materials science and carbon dioxide utilization. Furthermore, she has tutored 2 Master’s theses, supervised 1 Master’s-level project and 3 Bachelor-level projects, and participated in the organization of major events such as the 22nd International Conference on Carbon Dioxide Utilization and the CO2 for Sustainability Workshop. Within national and international R&D projects on CO2 electroreduction, green hydrogen and advanced energy materials, in collaboration with industrial and research partners such as PRIO Energy and HyLab – Green Hydrogen Collaborative Laboratory, she plays an active role in integrating simulation-driven design into experimental workflows and prototype development in the field of carbon capture, utilization and solar fuels.
