Short CV

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 and tomographic imaging.

Research Interests

My main research area around the mathematical foundations of Image Analysis.

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
and applications of these methods.

Teaching Activities

Currently I teach a few courses:

  • Numerical Solutions of Differential Equations: Finite Difference Methods (NumDiff) - I am course Responsible, here you can get info about NumDiff 2017, though it still may change.
  • Vision and Image Processing (VIP) - course responsible Søren Ingvor Olsen.
  • Modelling and Analysis of Data (MAD) - course responsible Aasa Feragen.
  • Computational Methods in Simulation (CMIS) - course responsible Kenny Erleben .
Past courses include

  • Signal and Image Processing (SIP),
  • Introduction to Programming (Grundlæggende Programmering) (KOMIT IP),
  • Mathematics for Science (MatNat).
