Born in Turnhout, Belgium, in 1959.

Wim started off in the mid 70s as a “field investigator” for the Studiegroep voor Progressieve Wetenschappen/Groupement pour l’Etude des Sciences d’Avant-Garde (SPW/GESAG).
He headed the Studiegroep voor Vreemde Luchtverschijnselen (SVL) and edited the group’s journal (SVL Tijdschrift) from 1982 till 1987.
In 1994 Wim initiated CAELESTIA, a research initiative that seeks to find explanations rather than promote mysteries.
In 2007, together with Frederick Delaere, he set up the Belgisch UFO-meldpunt to monitor UFO reports in Belgium.
