He is known for writing scholarly works and giving lectures throughout Europe on J.R.R. Tolkien. At the turn of the century, Ferré worked both on translating Tolkien literature to French, under Christian Bourgois, and then on providing the French dubbing of Peter Jackson's 2002 film The Lord of the Rings: The Fellowship of the Ring. In the decades following, he supervised or worked on many further French translations, and has contributed essays to Walking Tree Publishers' Cormarë Series.
He founded and runs a personal website, Pour Tolkien, for news and information on editions, Q&A, translations, et cetera.
Ferré is featured throughout François Busnel's documentary J.R.R. Tolkien, the Lord of the Writers. In 2019, he will help orchestrate a Tolkien exhibition held at the National Library of France in Paris.
