I hold a Bachelor’s degree (2022) and a Master’s degree (2024) in Chemical Engineering from Instituto Superior Técnico (IST), where I specialized in sustainable materials and biomass valorization. My Master’s thesis, developed within the FCT-funded BioCFiber project, focused on lignin-based copolymers for renewable carbon fiber precursors. In 2025, I began my Ph.D. in Chemical Engineering at IST, working on the development of bio-based hybrid materials for solar-driven photocatalytic wastewater treatment, integrating green chemistry and advanced materials design. I have solid experience in analytical and materials characterization techniques, including ATR-FTIR, TGA, DSC, GPC-IR/UV, NMR, SEM, DLS, PSA, and UV-Vis spectrophotometry. Additionally, I served as an Invited Assistant for one academic year, where I strengthened my teaching, scientific communication, and content-structuring skills.
