Introduction
I am professor of GIS and remote sensing at the Department of Geography of the Vrije Universiteit Brussel and chair of the Cartography and GIS Research Group. My research focuses on the development of remote sensing and GIS driven approaches for monitoring and modelling of urban dynamics in the context of urban ecology and urban sustainability studies. Earlier in my career I did a PhD on small-scale map projection design and published two handbooks on the topic of map projection.
