Charles is a Lead Developer Engineer on the Scientific Visualization team at Kitware Europe. He joined Kitware in February 2016.

During the first 3 years at Kitware, Charles worked on his PhD on “High performance level-set based topological data analysis” in cooperation with Sorbonne University. During his research work, he became one of the main contributor of the TTK library.

After defending his thesis, Charles joined the Scientific Visualization team where he mainly works on maintaining VTK and TTK.
His main subjects are high-performance computing, meshing and discrete geometry.
