Reynaud-Dewar studied ballet with Colette Milner at the Conservatoire de La Rochelle, then Public Law at the University of Paris I Panthéon Sorbonne.
During the years immediately after her MA, she mostly devoted herself to writing about art in various magazines and artist's monographs and producing sculptural installations which functioned as sets for her performances.
She has investigated the boundaries of biography, and has developed her work around various historical figures of transgression such as Josephine Baker, Cosey Fanni Tutti, Sun Ra, Jean Genet and Guillaume Dustan.
With her students from Head Geneva, she has made a horror comedy in Marfa, TX, entitled "Beyond the Land of Minimal Possessions"[5] and which deals with the gentrification brought by art institutions.
Maladie d'Amour is a social and emotional experiment that brings a small group of young people around one-night long exhibitions featuring Lili Reynaud-Dewar's artist friends such as Thomas le Lann, Marina Faust, Ian Wooldridge, Helene Cayet, Matthis Collins, Bonny Poon, and Hugo Scibetta.
