I am an associate professor HDR in the Electrical Engineering Department at INSA Lyon and in the CREATIS lab, CNU 61, doctoral school EEA.

Short bio
I received my Electrical Engineering degree from ISTASE (now Telecom Saint-Étienne) in 2001, my M. Sc. degree (major in Image Processing) from the University of Saint-Étienne in 2001, and my Ph.D. degree (Image Processing) from the National Institute for Applied Sciences of Lyon (INSA-Lyon, France) in 2005. In 2023, I obtained the HDR (Habilitation à Diriger des Recherches) at INSA-Lyon / Université de Lyon with the doctoral school EEA (more details here).
I have been with CREATIS, a joint laboratory of the « Centre National de la Recherche Scientifique » (CNRS), the « Institut National de la Santé et de la Recherche Médicale » (Inserm), the « Institut National des Sciences Appliquées de Lyon » (INSA Lyon), and the « Université de Lyon » since 2001. My research interests are in medical image segmentation, clustering, and filtering, particularly in methods involving feature space and scale-space approaches and deep learning approaches. I am affiliated to the Myriad team of CREATIS. I have contributed to 20 papers and co-supervised 6 PhD students.
