After multidisciplinary training in dance, theater and music in Barcelona, Aina Alegre joined the CNDC in Angers in 2007. In this way, she articulates choreographic objects constructed from different media: pieces for the stage and performances in hybrid spaces.

In 2014, she founded the STUDIO FICTIF company in Paris to accompany her projects and creations. Since then, her work has beeń presented in various countries including Spain, France, Italy, Belgium, Greece, Switzerland, Germany, Peru and Romania.

In 2011, she created the performance LA MAJA DESNUDA DICE, a proposal that led to the creation of the piece NO SE TRATA DE UN DESNUDO MITOLÓGICO (2012). She subsequently created DÉLICES (2015), LE JOUR DE LA BÊTE (2017) and LA NUIT NOS AUTRES (2019). In 2020, she creates CONCRERTO in collaboration with David Wampach and the solo R-A-U-X-A. In 2021, she creates ÉTUDE 4, FANDANGO ET AUTRES CADENCES, at the Avignon Festival as part of the “Vive le sujet!” program co-produced with SACD. In 2022, she creates her first major group piece THIS IS NOT (AN ACT OF LOVE & RESISTANCE). In June 2023, she opened the Marseille Festival with PARADES & DÉSOBÉISSANCES, a piece for 100 amateurs, and created SWING-MOTOR for the Jeune Ballet du CNSMD de Lyon in November of the same year. Alongside her stage projects, since 2018 she has been setting up the research and performance project ÉTUDES with which she encounters people and territories and collects stories around practices and dances linked to the gestures of hammering and striking. She works with memory and archives, using the spoken word as a choreographic driving force.
