With a BSc and MSc in Chemistry, I am currently a PhD student in Chemical Engineering, specializing in the valorization of biomass for sustainable material development. My research focuses on biobased polymers as active ingredients for eco-friendly formulations, particularly in personal care applications. With five years of experience in biomass valorization, I apply green chemistry principles to extract and characterize bioactive compounds, optimize processes, and develop functional materials. My expertise includes bioactive extraction from lignocellulosic sources, materials characterization, data analysis, and process optimization, contributing to the development of advanced biobased materials and sustainable formulations. Beyond research, I have mentored MSc students in Chemical Engineering and actively participated in scientific outreach, organizing workshops and public engagement initiatives. I am passionate about interdisciplinary collaboration and committed to bridging sustainability and innovation in biomaterials.
