Short Biography

Stefano Barbieri a obtenu son doctorat en physique en 2000 à l’École Normale Supérieure (Pise, Italie). En 2000, il rejoint en tant que chercheur R&D Orbisphere SA (Genève, Suisse), où il s’est dédié au développement de systèmes de détection de gaz basés sur l’exploitation de l’effet photo-acoustique. En 2002, il rejoint TeraView Ltd (Cambridge, Royaume-Uni) où il coordonne une activité de R&D axée sur les lasers à cascade quantique THz en collaboration avec le Laboratoire Cavendish de l’Université de Cambridge. En 2004, il reçoit une bourse industrielle de trois ans de la Royal Society visant à promouvoir le transfert de technologie entre industrie et université. En décembre 2005, il est recruté par le CNRS en France. De 2005 à 2016, il se dédie au développement de dispositifs THz au Laboratoire MPQ de l’Université Paris Diderot (Paris, France). Depuis 2016, il a rejoint le groupe Photonique-THz du Laboratoire IEMN (Lille, France). A présent, ses activités principales concernent les détecteurs ultrarapides et les modulateurs dans l’infrarouge moyen à base de semi-conducteurs III-V.
