Elisabeth Bouchaud  Elisabeth Bouchaud (born Tibi) is a French physicist, playwright and actress born 1 March 1961. She is a member of Commissariat à l'énergie atomique (CEA), and works at Ecole Superieure de Chimie et Physique de la Ville de Paris. Since 2015, she is also the Director of the Théâtre de la Reine Blanche in Paris. She has worked in quantitative fractography, establishing some "universal" fractal properties of fracture surfaces, a subject pioneered by Benoit Mandelbrot. In fact, the term "fractal" itself was coined by Mandelbrot in 1975, based on the Latin frāctus meaning "broken" or "fractured". Elisabeth Bouchaud suggested that these fractal properties could be understood in terms of the propagation of the crack front in a disordered environment, which is affected by the vicinity of a depinning transition. She was awarded the Louis Ancel Prize, the Onsager Medal, and the Aniuta Winter-Klein Prize. Elisabeth Bouchaud wrote several short stories and plays. Two plays of them were presented at the Avignon Festival: "A Contre Voix" in 1994 and in 2000, and "Apatride, la Tragédie de Médée" in 2013. "A Contre Voix" was translated into English by Mary Luckhurst and put on at the Grace Theatre, London, in 1994. Her other plays are "Les liaisons dangereuses" (1989), "Musical Box" (1996), "De la matière dont les rèves sont faits" (2005) and "Puzzle" (2015), a stage adaptation of "Puzzle of a Downfall Child" by Jerry Schatzberg, put on at the theatre "La Reine Blanche" in 2017.
