Biologist and filmmaker, Thomas Julienne has a deep passion for wildlife and vast wilderness areas, still preserved from human impact. After making his first film documenting his crossing of Lapland and embarking on a voyage to Iceland aboard the sailing boat of the Arvik Océan association, he decided to travel by bicycle through Argentina and Chile to study the cohabitation between pumas and livestock farmers. This project gave birth to the film Coexistencia, Sur les Traces des Pumas, already award-winning at festivals, and currently on tour throughout France.
