Because of my public activities relating to the controversial subject of UFOs, I am best known as a speaker in this field of investigation and research. This Page aims to rectify this characterization of my work to highlight my other achievements as a researcher in ancient history, in the history of literature and in the narratology of testimonies and etiological stories.
