Callard Ségolène

Ingenieur Centrale Lyon (1993) and holder of a doctorate in condensed matter physics (1996), Ségolène Callard joined Centrale Lyon in 1998 after a post-doctoral stay at the Institut National de la Physique des Matériaux in Italy, within ST-microelectronics in Milan. University Professor since 2008 (CNU28), she teaches in various fields of physics, and more specifically light/matter interactions and quantum mechanics. A researcher at the Institut des Nanotechnologies de Lyon (UMR CNRS 5270), she is interested in ultimate light confinement phenomena in photonic nanostructures and their characterization by optical near-field microscopy techniques, whose activity she has developed at INL. From 2012 to 2020, she held the position of Directrice adjointe des études pour le tronc commun at Centrale Lyon and was involved in defining and setting up training courses, in liaison with the regional fabric of other higher education establishments, notably the Ecole normale Supérieure de Lyon. Deputy Director of INL since 2021, she currently contributes to the unit's scientific and strategic orientations and assists the Director in managing laboratory staff and infrastructure.

Research projects
