David contributed several times to the Plone documentation effort with tutorials and how-tos covering key theming techniques. He developed DIYPloneStyle, a product and a tool that helps theme developers start with the basic generated code. The effort started with DIYPloneStyle is now merged in the theming templates of ZopeSkel, which he maintains.
David is currently employed at the Royal Belgian Institute of Natural Sciences. He's been working there for the MARS (Multimedia Archaeological Research System) project; a collaborative system based on Plone designed for Archaeologists and Anthropologists, and is now helping the web team at the institute.
