Since 2012, Diane Clément has been developing her own opera staging projects.

With a degree in musicology, she was first stage and production manager and then assistant to numerous directors in opera. She collaborates in particular with Patrice Chéreau, Trisha Brown and Laurent Pelly at the Paris Opera, Jean-François Sivadier and Ludovic Lagarde at the Lille Opera, Krzysztof Warlikowski at the Aix-en-Provence festival, Olivier Py at the Theater de la Monnaie in Brussels, Bob Wilson and David Cronenberg at the Théâtre du Châtelet, Moshe Leiser and Denis Podalydès at the Théâtre des Champs Elysées.

For Laurent Pelly, she revived shows twice: Don Quichotte (Massenet) at the Palermo Opera in 2010, and Le Roi malgré lui at the Opéra comique in 2009 and more recently for Willy Decker that of La Clemenza di Tito, in collaboration with Jean-Louis Cabané at the Paris Opera.

In 2012, for the Wagner200 opera staging competition, she developed a project around Der fliegende Holländer, with Barbara del Piano, in charge of the costume creation, and then for Opera Europa around Cavalleria rusticana - Pagliacci.

For her participation in the Ring Award 2014, this time she entrusted Barbara del Piano with the scenography and costumes for the Der Freischütz's project. This pair will allow them to reach the semi-finals of this prestigious competition.

When they staged Carmen for the first time at Salle Ravel in Levallois-Perret in 2014, they naturally chose to continue their collaboration. The team grew on this occasion by welcoming Grégoire Delafond for the creation of lights. In March 2016, they were invited to the same room to stage Puccini's La Bohème.

Together, they are preparing a Der Freischütz for the 2021-2022 season.
