Research

My research interests lie in the field of surface processing, in particular when the surfaces are represented as point clouds. It includes surface denoising, meshing, scan merging and surface segmentation.

I started working on those topics during my PhD with Jean-Michel Morel at CMLA (ENS Cachan). My PhD defense took place on 2010, November, the 23rd.

I am now a post-doc at the INRIA Sophia Antipolis (Geometrica team) with Pierre Alliez.

Starting October 2012, I will be at LIRIS (équipe Géomod) as a CNRS permanent researcher.
