Doctor of physical sciences graduated from the Swiss Federal Institute of Technology in Lausanne (EPFL) in close collaboration with the European Organization for Nuclear Research (CERN). I have always had a deep respect for the conscientious and talented teachers who are the lifeblood of our future generations. As a Japanese saying goes: “A single conversation with a wise man is better than ten years of study. ". I hope to be able to share with you today the thirst for knowledge that these people transmitted to me in a clear, simple and effective way so that you too can succeed in physics and mathematics. Do not hesitate to write to me via this messaging. I teach at all levels and ages and I am happy to travel anywhere in French-speaking Switzerland.
