An Adventure into the World of Soft Matter

Soft matter is a field of condensed matter physics that began to develop in France in the 1970s under the impulse of Pierre-Gilles de Gennes. I had the chance to participate in this adventure, and I describe in this article some of the memorable events. Soft matter is not only linked to physics but also to chemistry and biology, and working in this multidisciplinary field is quite stimulating. My particular expertise deals with liquid surfaces, an area that considerably expanded with the advent of miniaturization, i.e., when surfaces begin to matter. I was able to benefit from the French and European network systems, as well as from many interactions with young students and industrial partners. I show how these favorable conditions contributed to successes in my research.
