An expert in the manufacture of handmade paper, Tiberi is a lecturer and consultant in the development of laboratories for the production of handmade paper. He also collaborates with various associations for people with disabilities, involving them in the manufacture of handmade paper as a method of social reintegration.

Tiberi’s hometown of Fabriano was designated an UNESCO (United Nations Educational, Scientific and Cultural Organization) Creative City in the area of Crafts and Folk Art along with Paducah in October 2013. As early as the 13th century, Fabriano was one of the first places in Europe to make high-quality paper on an industrial scale. Fabriano’s long standing reputation for fine watermarked paper continues to be highly regarded by today’s artists. Tiberi’s creative installations and workshops made a decisive contribution to Fabriano’s recognition as an UNESCO City of Crafts and Folk Art. His paper installations have been exhibited at the UNESCO headquarters in Paris, France.
