Born in 1958, graduated in physics, has been professor of civil engineering at the Universities of Marne-la-Vallée and (presently) Bordeaux.

Since 1985 he has been coordinating Project Bécassine, aimed at an electronic coding, catalogue and statistical analysis of more than 2300 humanoid reports worldwide.

He wrote several articles about the above-mentioned project, published mainly in French UFO journals, and published a series of project updates.

Some contributions were also published in UFO books (e.g. De l’indiscernabilité identifiés – non identifiés in the collective book OVNIs: vers une anthropologie d’un mythe contemporaine [1993]).
