I studied Mathematics in France, University of Nice Sophia Antipolis where I got a PhD in Algebraic Geometry in 1994. I spent some years in Burkina Faso, West Africa, where I taught Mathematics at the University of Ouagadougou. I moved then to Denmark and engaged in yet another PhD, at the IT University of Copenhagen, degree awarded in 2004. I worked on Variational Methods for Motion Compensated Inpainting and motion recovery among other. I have since mainly worked with variational methods, and geometry for Image Analysis (mainly Riemannian, but also some metric geometry). More recently, I have spend some time with inverse problems in photometric stereo, tomographic imaging, some geometric deep learning, 3D vision with refraction.

Currently I am particularly interested in imaging inverse problems, including

- Variational Methods for Video Sequences Processing
- Geometry for Shape spaces
- Photometric Stereo
- Tomography
- Segmentation
- Variational Methods in the Riemannian Geometry Setting
- 3D reconstruction methods when refraction comes into play.
