RP´s expertise was primarily cultivated through his multidisciplinary education. He holds a degree in Chemistry from the University of Porto (2004), a master’s degree in Materials (2008), and a doctorate in Chemistry from the University of Aveiro (2012). During his PhD, he acquired a solid formation in the synthesis and characterization of nanostructures and gained valuable experience in scaling up nanoparticle production for modern papermaking through his participation in the EU project SUNPAP. In 2013, he was awarded a postdoctoral grant (€108k) by FCT to work at CICECO/UA, focusing on developing novel biobased composites, demonstrating how nanostructures can enhance properties and expand their range of applicability. In 2019, he was hired as a researcher (a position held until December 31, 2024), making a conscientious shift toward more sustainable materials and methods. During this time, he gained extensive expertise in designing biobased nanoparticles through 'green' synthesis methods, a key element of the proposed project. Since then, he has established an independent research line within his group, achieving some scientific independence. He has made significant contributions to the field, authoring 53 publications (h-index: 27; >2600 citations) in high-impact journals (over 90% in Q1), along with 1 book, 3 book chapters, 4 conference proceedings, and more than 90 presentations at national and international conferences, including 2 invited talks at ICNRI (2023 and 2024). His key role is highlighted by his position as the first (15), corresponding (9), and last author (1). RP’s expertise is further demonstrated by his role as Invited Guest Editor for two special issues on the biosynthesis of nanostructures (Nanomaterials) and eco-friendly/sustainable approaches (Polysaccharides). RP regularly reviews high-impact journals in nanostructured materials and biobased methodologies, with 78 reviews completed. Throughout his career, he has participated in 3 international and 7 national projects. In the past four years, he has been directly involved in 6 national/international projects, serving as co-PI in one and as task leader and only senior researcher for the host institution in two, managing allocated budgets. His international recognition is highlighted by invitations to the editorial boards of Nano Materials Science (Elsevier) and Polysaccharides (MDPI). Additionally, he has reviewed projects and grants for the National Agency of Innovation (ANI) and served as an expert reviewer for the Hellenic Foundation for Research & Innovation (HFRI). He has supervised 20 BSc, 10 MSc, and 2 PhD students, and mentored some postdoctoral researchers. Currently, he supervises 2 Research Fellows, 1 MSc, and 2 PhD students. He has served as the main jury for 8 BSc and 13 MSc evaluations and has actively contributed to organizing national and international workshops and conferences over the past 4 years, including member of the organizing committee for the BEST Summer School 2022 and 2nd International Conference on Nanotechnology Research and Innovation and the local organizing committee for two FUR4Sustain Meetings (Cost Action CA18220). He is a member of the Portuguese Society of Chemistry (SPQ) and the European Polysaccharide Network of Excellence (EPNOE). His international mobility includes research stays at the Grenoble Institute of Technology (France) and INNOVHUB (Italy), developing also a strong academic-industry network, including consulting for the startup DNA TRUSTAG (2016–2017). Beyond research, he has been involved in regular teaching activities (3 h/week) at the Department of Chemistry, University of Aveiro in the last 3 years.
