Expertise

Mon parcours, qui s’inscrit du côté du journalisme économique, avec un intérêt particulier pour les enjeux numériques, m’a conduit à me former à ce qui constitue aujourd’hui mon quotidien : le datajournalisme. Je suis responsable de la cellule Data & Lab du Groupe mind, dont la mission est d’aider nos rédactions sur toute la chaîne de valeur de la donnée : identifier des sources fiables, récupérer, analyser pour trouver les signaux au milieu du bruit, mettre en récit et visualiser pour rendre l’information claire et accessible. Je m’intéresse au potentiel des données ouvertes et aux traces numériques pour améliorer la transparence de certaines activités économiques.
