Nicolas Dobigeon a reçu le Diplôme d'Ingénieur en Électronique de l'ENSEEIHT et le D.E.A. (Master Recherche) en Traitement du Signal de l'Institut National Polytechnique de Toulouse (INP Toulouse) en Juin 2004. En 2007, il a obtenu un Doctorat en Traitement du Signal de l'INP de Toulouse et, en 2012, il a reçu l'Habilitation à Diriger des Recherches (HDR) de l'INP de Toulouse. De 2007 à 2008, il a été chercheur post-doctoral associé au Département Electrical Engineering and Computer Science de l'Université du Michigan à Ann Arbor.

En 2008, il a été nommé à l'Institut National Polytechnique de Toulouse (Université de Toulouse, INP-ENSEEIHT) où il est actuellement Professeur. Il mène ses activités de recherche au sein de l'équipe Signal et Communications du laboratoire IRIT (UMR CNRS 5505) et est aussi membre académique du laboratoire coopératif TéSA (Télécommunications Spatiales et Aéronautiques).

Ses activités de recherche concernent principalement le traitement statistique du signal et des images, avec un intérêt particulier pour les problèmes inverses bayésiens rencontrés en télédétection, imagerie médicale et génomique.

Depuis 2013, il est membre du comité de direction du GdR ISIS.

De 2012 à 2016, il a été membre élu puis nommé au Conseil National des Universités (CNU 61).

Depuis 2011, il a également en charge la formation de spécialité "Traitement du Signal et des Images" au sein du Département Electronique de l'INP-ENSEEIHT.

Il est IEEE Senior Member.
