I hold a PhD in Conservation and Restoration of Cultural Heritage from NOVA School of Science and Technology (2017) with a thesis focused on the preservation of polyurethane. From this experience, I acquired a strong expertise in advanced analytical techniques such as infrared and Raman spectroscopies for the assessment of both polyurethane ageing and storage preventive solutions for this polymer. Establishing conservation strategies for urgent needs in museum collections holding challenging materials such as plastics has been the core of my research and the biggest motivation behind my career growth. Since 2011, I have integrated 6 funded research projects, all focused on the preservation and history of plastics, as well as on the development of novel and green solutions for their conservation. I have gained an independent research profile in the study of plastics, foams and rubbers degradation. From my expertise, I was recently invited to integrate the funded research project ‘Glossy Surfaces - The Conservation of TPUs in Fashion’, an international consortium with renowned museums and research centres such as MoMu (Belgium), MET (EUA), MUDE (Portugal) and Centexbel (Belgium). In 2018 I became an Invited Assistant Professor at DCR FCT NOVA. In 2018, I co-founded the first spin-off of DCR, NEON Art Conservation Lda. NEON is the first company in Lisbon dedicated to the conservation of modern materials.
