On Thursday, November 12, 2026, ESTIA organized its PhD Day, an event dedicated to discovering and valuing the research work carried out by its doctoral candidates. This event aimed to highlight the diversity of scientific projects developed within the school.
Two doctoral candidates presented their research topics: Safia Yelles Chaouche, whose work focuses on multi-agent holonic digital twins for the planning and management of production systems, and Romain Deloffre, studying the reuse of INCONEL 625 powders in DED additive manufacturing and its impact on the properties of manufactured parts. This research demonstrates ESTIA's commitment to innovative solutions for industrial transformations.
The 'My Thesis in 180 Seconds' exercise was another highlight, inviting four doctoral candidates to present their research subjects in just three minutes. Lucille Rey addressed software developers' well-being at work, Abu Bakar Siddique presented the design of a 360° screen capable of changing shape while maintaining constant pixel density, Paul Galtayrie discussed scenarios for transition towards absolute sustainability applied to metallic additive manufacturing, and Quentin Plisson focused on the participatory design of sustainable energy systems at the territorial level. This exercise allowed doctoral candidates to share their research in a concise format, promoting the understanding and dissemination of scientific knowledge.
Beyond the presentations, the PhD Day served as a valuable opportunity to showcase ESTIA's research activities and recognize the commitment of those who contribute daily to advancing knowledge. This initiative also underscores the importance of research within ESTIA's ecosystem, at the intersection of education, innovation, and industrial and societal challenges.
