João Vitor Fabian is a PhD student in Chemical Engineering at the University of Aveiro, currently involved in the European ILIMITED project. He holds a master’s degree in Chemical Engineering from the Polytechnic Institute of Bragança (2024), completed through a double-degree pathway with the Federal University of Technology – Paraná, Brazil, where he also obtained his bachelor’s degree. His academic trajectory has focused on thermodynamic modelling, separation processes, and sustainable chemical technologies, with increasing specialization in ionic liquids for high-temperature applications. During his undergraduate studies, he worked on thermodynamic modelling of the ethanol–water–glycerol system for anhydrous ethanol production, building a strong background in phase equilibria and thermodynamic analysis. In his master’s degree, he developed research on biodiesel purification through adsorption using walnut-shell-derived adsorbents, gaining experience in experimental design, process evaluation, and analytical characterization. His current doctoral research focuses on ionic liquids for high-temperature CO2-to-methanol processes, combining COSMO-based thermodynamic modelling, computational screening, and experimental assessment of long-term thermal and chemical stability. He has presented his work at several national and international conferences and is currently preparing two scientific manuscripts. In addition, he has experience as a university tutor, in academic event organization, and in an international internship in Egypt related to solar energy. Overall, his path reflects a consistent progression toward research in Chemical Engineering, integrating thermodynamics, experimentation, and sustainable process development.
