Meritxell Romans Casas pursued a double degree in Biology and Biotechnology at the University of Girona and graduated in 2019. That same year, she completed a master's degree in Science and Technology of Water Resources, earning the promotion's honors mention. Subsequently, she joined the LEQUIA research group at the same university, initially for a brief period as a technician and later as a doctoral student, focusing on the valorization of CO2 into value-added compounds through advanced technologies, bioelectrochemical systems, and secondary fermentations. Throughout the PhD, activities related to various national and European projects were carried out. Additionally, two international stays were completed, one at the University of Tampere (Finland) and another at Wageningen University (Netherlands). During this period, she attended and contributed (oral presentation or poster) to several national and international conferences, published articles in high-impact scientific journals, and obtained a patent (EP23382585). She also had the opportunity to supervise undergraduate and master's students in laboratory internships.
