Andreia Melissa Afonso completed her PhD in Agricultural and Environmental Sciences in 2023 at the University of Algarve, with a thesis titled "Non-invasive monitoring of kiwifruit ripening". She also earned her Master’s Degree in Biological Engineering in 2016 from the same institution. Her research primarily focuses on the application of visible/near-infrared spectroscopy to assess fruit quality during both pre-harvest and post-harvest stages. This includes the determination of key quality parameters such as firmness, dry matter content, soluble solids content, juice pH, and titratable acidity using both traditional methods and non-invasive technologies. Additionally, her work extends to the early detection of phytopathological symptoms in plant leaves through visible/near-infrared spectroscopy and plant molecular biology techniques, including DNA and RNA extraction from various plant tissues. From September 2021 to May 2024, Andreia worked as a researcher, consultant, project manager, and creator of self-learning digital content in precision agriculture at Duas Siglas – Formação e Investigação, Lda. During this period, she managed the NIBAP – Núcleo de Investigação em Biotecnologia e Agricultura de Precisão project, coordinated knowledge-transfer events, and successfully led the implementation of the Research, Development, and Innovation Management System (NP4457:2007), including its transition to NP4457:2021. Since May 2024, she has been working as a researcher at the Decentralized Laboratory of the Centro de Biotecnologia Agrícola e Agroalimentar do Alentejo (CEBAL) in Odemira.
