Thierry comes from the flattest country in Europe, and works as a teacher-researcher in the space field, both at the university in Orléans and at a research institute in Switzerland. One of his specialities is the study of the impact of solar activity on our terrestrial environment.

His involvement with A Rocha dates back to 2021. It is the culmination of a journey that began with the fight to rid the scientific debate of unfounded attempts to deny mankind’s role in global warming. This was followed by an awareness of the systemic crisis into which humanity is sinking, with intense questioning. The culmination of all this was the discovery of the hope to which God is calling us, and of the possibility of associating this hope with a concrete commitment to the living.
