Research interests

My research activities mainly concern the study of problems involving image data

Methodologies: optimal transportation, variational methods, machine learning, data assimilation

Applications: computer vision, computational photography, oceanography, medical imaging


I received the M. Eng degree in applied mathematics from the National Institute of Applied Sciences, Rouen, France, in 2004 and the M. Sc in Analysis from Rouen University in 2004. I obtained the Ph.D. degree in applied mathematics from the University of Rennes, France, in 2007, under the supervision of Étienne Mémin, with long stays at the Laboratorio de Fluiodinámica de Buenos Aires, Argentina in 2006 and 2007. From 2008 to 2010, I had a postdoctoral position in Barcelona Media, Spain, under the supervision of Vicent Caselles. I joined the CNRS (section 07) as a full researcher in 2010 in the Inria MOISE team (now AIRSEA team) at the Laboratoire Jean Kuntzmann, Grenoble, France. Since 2013, I work in the Institut de Mathématiques de Bordeaux in the IOP team. I realized a long stay in the Cambridge Image Analysis group at the Department of Applied Mathematics and Theoretical Physics of the University of Cambridge, UK, in 2018-2019.
