Francesca Diglio is a Research Fellow at the Department of Industrial Engineering of the University of Naples Federico II. She earned her Master’s Degree in Building Engineering-Architecture in 2021, with a thesis investigating daylighting and electric lighting conditions in residential spaces repurposed as workspaces during the pandemic (Covid-19). In 2025, she obtained her PhD from the same university, focusing her doctoral research on the interactions between light and materials and on the integration of daylight and electric light to enhance building energy performance and user comfort, considering both visual and circadian aspects. Her research activities primarily address the integration between daylight and electric light and its impacts on building energy efficiency, visual performance, and light-induced non-visual responses (both short- and long-term). Additionally, she explores lighting solutions for cultural heritage. At the international level, she has collaborated on the activities of Task 70 | Low Carbon, High Comfort Integrated Lighting within the International Energy Agency (IEA). She is a member of the Italian Lighting Association (AIDI) and the Italian Color Group (Gruppo del Colore).
