Mario Trimarchi was born in Messina. He graduated in Architecture with Franco Purini, with whom he collaborated on some projects in Sicily. In the 1980s he moved to Milan, where he lives and works. In the early 1990s, he was the director of the Master in Design at the Domus Academy and later headed the DDA, a joint venture between the Domus Academy and Mitsubishi, alternating long business trips to Japan with conferences, lectures and workshops in various countries throughout the world. In 1999 he founded Fragile, a corporate identity studio, where, in parallel with strategic positioning and communication projects for companies and institutions, he continued his personal research on design. For nearly ten years he was part of the Olivetti Design Studio, where he designed, along with Michele De Lucchi, personal computers and cash dispensers. During the same period he studied how to give a domestic touch to technological innovation, creating concept designs and products for Philips, Siemens and Matsushita Denku. From 2005 to 2015 he taught Corporate Identity at the University of Genoa and since 2013 teaches the Brand Design Course as part of the Product Design specialist degree at the Naba in Milan.
Since 2016 he is the Design Advisor for the Korea Craft & Design Foundation.
