After graduation, he was involved in architectural practice for about 4 years, before returning to the KU Leuven for his PhD in 2007 on the integration of Building Information Modeling (BIM) in the design process. He worked on a variety of research and education projects, ranging from CAD and BIM to metadata for architectural archives and cost simulations. His main research interests are BIM, 3D modeling and visualization, digital historical reconstruction, parametric design, programming, and interoperability between a variety of software tools, with a special focus on openBIM.
