I am a second year PhD student in the LaSTIG lab at the French National Mapping Agency (IGN). I am also part of the IMAGINE group at Ecole des Ponts ParisTech (ENPC). The topic of my PhD is "Structured 3D City Reconstruction from Heterogeneous Data". My advisors are Bruno Vallet, Renaud Marlet and Loic Landrieu. My research interests are centered around the fields of computational geometry, 3D machine learning and 3D GIS. I graduated from Delft University of Technology with a MSc in Geomatics and from the University of Stuttgart with a BSc in Geodesy and Geoinformatics.
