After graduating with a DEA in economics, Martyne finally decided to pursue an acting career. Regularly at the theatre, she delves back into the world of economics with Court Sucré or Long Sans Sucre where she shares the stage with Olivier Yéni. She also finds it in Climate Warming in 2009, but also in the awareness workshops on Taking the Word that she hosts and the sketches that she performs for Act Seven. Martyne has been combining writing and acting for many years. His meeting with Bruno Chapelle at the Petit Théâtre de Bouvard gave birth to plays like "Daddy Blues" à la Michodière or «I almost waited» at the comedy Bastille. Today, she has the pleasure of playing in her plays.
