A researcher and author whose name runs through cases on three continents. He came to interview Maurice Masse after the 1965 Valensole encounter, alongside Aimé Michel and Charles Bowen. April 1980. He stood at Morro do Vintém and found a bare clearing where grass had not grown back after 14 years. In 1977 he traced the wave of lights along the coast of Pará toward Colares, and in 1988 he re-investigated Trans-en-Provence, having original samples retested at a US laboratory. With Paola Harris he published Trinity: The Best-Kept Secret in 2021.
