After completing a multidisciplinary training program combining dance, theater, and music in Barcelona, Aina Alegre joined the CNDC in Angers in 2007. Beginning in 2010, she worked as a performer while also creating stage productions and performances in hybrid spaces. In 2014, she founded the company STUDIO FICTIF in Paris to support her projects and creations. Since then, her work has been presented in various countries, including Spain, France, Italy, Belgium, Greece, Switzerland, Germany, Peru, and Romania.

In 2011, she created the performance *LA MAJADESNUDA DICE*, which led to the creation of the piece *NO SE TRATA DE UN DESNUDO MITOLÓGICO* (2012). She subsequently created *DELICES* (2015), *LE JOUR DE LA BÊTE* (2017), and *LA NUITNOS AUTRES* (2019). In 2020, she created the piece CONCRERTO in collaboration with David Wampach and the solo R-A-U-X-A. In 2021, she created ÉTUDE 4, FANDANGO ET AUTRES CADENCES at the Avignon Festival as part of the “Vive le sujet!” program, co-produced with the SACD. In 2022, she premiered her first major group piece, THIS IS NOT (AN ACT OF LOVE & RESISTANCE). In 2023, she premiered SWING-MOTOR for the Jeune Ballet du CNSMD de Lyon. That same year, she opened the Marseille Festival with PARADES & DÉSOBÉISSANCES, a piece bringing together over a hundred amateur dancers, which was revived in 2024 at the Palais des Sports in Grenoble. Since May 2024, she has been performing BLAU in museum settings, a solo piece originally conceived for the Miró exhibition at the Musée de Grenoble. In March 2025, she premiered FUGACES at the MC2: Grenoble, a piece for seven dancers. In July 2025, she presented a new version of PARADES & DÉSOBÉISSANCES, in collaboration with Bonlieu Scène nationale Annecy, as the opening performance of Annecy Paysages and at the Défilé de la Biennale de Lyon.
 
Alongside her stage projects, since 2018 she has been developing the research and performance project ÉTUDES, through which she engages with people and communities and collects stories and dances centered on practices and movements related to hammering and striking. She works with memory and archives, using speech as a choreographic driving force. In the fall of 2024, she presented her latest study, RÉVERBÉRATIONS - ÉTUDE 8, at the Festival Les Inaccoutumées at the Ménagerie de Verre in Paris.

Since 2023, she has co-directed the Centre chorégraphique national de Grenoble with dancer Yannick Hugron.
