Having graduated in both mathematics and computer science, Reto became involved in audio-visual conservation and restoration thirty-seven years ago. He has been running his own preservation company, AV Preservation by reto.ch, and also lecturing at the Bern University of Applied Sciences, the Academy of Fine Arts Vienna and the Elías Querejeta Zine Eskola in Donostia (San Sebastián). His courses cover the conservation and restoration not only of audio-visual content but also audio-visual carriers, usually with a focus on technical issues and motion picture film. His current research is mainly focussed in the digital domain and includes colour spaces, look-up tables and codec programming and emulation, as well as methods to also restore actual files and the so-called raw data they hold.


Previously he was head of preservation at the Cinémathèque suisse as well as a lecturer at the University of Lausanne. He served as an Association of Moving Image Archivists (AMIA) board member for four years. Reto’s work has seen him honoured with one of the inaugural Joint Technical Symposium (JTS) Awards.
