After attending the life drawing school at the Accademia di Belle Arti di Venezia in the early 1960s, Gioli moved to New York, where he won a scholarship and came into contact with the New American Cinema movement. Following this experience he decided to pursue two other lines of research alongside painting: cinema and photography, experimenting with innovative techniques. He made his first films in the late 1960s upon returning to Italy, where he divided his time between Rovigo and Rome, during a period when the Cooperativa Cinema Indipendente was ceasing its activity. After a stay in Milan, the artist settled in Polesine in the mid-1970s. He has held a number of important solo shows, including exhibitions at the Centre Pompidou in Paris (1983), the Musée Réattu in Arles (1987), the Palazzo delle Esposizioni in Rome (1996) and the MUFOCO in Cinisello Balsamo (2008). A number of film institutions and festivals have shown a recent interest in his work, including the Harvard Film Archive. In 2015 he was invited to exhibit his work in the Italian pavilion at the Venice Biennale.
