Henri Stephanou

I am currently researcher and part-time lecturer at IHPST (Institut d'Histoire et Philosophie des Sciences et des Techniques, Institute for the History and Philosophy of Science and Technique), at University Paris-1 Panthéon-Sorbonne.

After twenty years in industry, since 2017  I spend two-thirds of my time researching topics in the philosophy of science and technology. In December 2023, I obtained my doctorate in philosophy under the supervision of Pr. Pierre Wagner, at the IHPST (Institute for the History and Philosophy of Science and Technology), a laboratory of the University Paris-1 Panthéon-Sorbonne / CNRS, with the following dissertation: "Reasoning with machines: is programming a form of knowledge?"

I am a graduate of Ecole Polytechnique and Ecole Normale Supérieure in Paris, and an agrégé in philosophy.
