Marti works in sculpture, video, installation, and photography. His oeuvre oscillates between geometric formalism rooted in op-art and organic forms stemming from the subconscious. One such example is his ceramic series. Using traditional pottery techniques, Marti creates sculptures that evoke perpetual motion by utilizing repetitive circular forms. The optical effect, akin to the hypnosis spiral, is a reference to Marti’s interest in the sensations related to loss of control and consciousness.

In his photogram series, Marti explores the technique by placing various objects on photosensitive paper in a darkroom, then developing them through direct exposure to light. He sometimes uses transparent digital prints such as those of cephalopods or fingerprints – recurring motifs in Marti’s work – which he places on argentic paper for the printing process. On some photograms, Marti then integrates personal photos taken with his iPhone over the years. These testimonies of his daily life, selected from a corpus of over 60,000 images, are fixed with white tape to the inner surface of the plexiglass casing surrounding the work, thus becoming part of it.

Using his materials to create imposing structures, Marti sometimes fills exhibition spaces with his complicated constructions, subverting the traditional mode of hanging works on walls and inviting visitors to enter his singular artistic world. He strives to connect with nature, aiming to communicate with its essence via ephemeral constructions for the use of other artists. In the Two Hotel project, Marti built a wooden structure on Piracanga Beach in Bahia, Brazil, referencing the One Hotel created by Alighiero Boetti in Kabul in the 1960s. A simple, minimally structured space, it serves as a living and working space for artists.

Since 1999 Marti‘s works are exhibited in different parts of the world across Europe, America and Asia. A major solo exhibition curated by Fanni Fetzer was presented at Kunstmuseum Lucerne in 2016. In 2015 Catherine Pavlovic curated a solo show at Parc Saint Léger, Pouges. Other important solo exhibitions took place at Wilde (Geneva, Switzerland), Centre Pasquart (Bienne, Switzerland) and Kunstverein Braunschweig (Germany). Recent group exhibitions include those at the Kunsthalle Frankfurt (Germany), Kunstmuseum Lucerne (Switzerland), Deutsche Bank Lounge Weltwirtschaftsgipfel (Davos, Switzerland), Collection Burger, Langen Foundation (Neuss, Germany), Busan Biennale (Busan, Korea), Sammlung Boros (Berlin, Germany), Museum Marta Herford (Germany), Kunsthalle Mainz (Germany) and the Swiss Institute in New York (USA). Marti‘s participation in the 54th Biennale in Venice in 2011, curated by Bice Curiger, earned the artist international recognition. Martis works are represented in the collections of the following institutions: Kunstmuseum Lucerne (Switzerland), Migros Museum für Gegenwartskunst  (Zurich, Switzerland), Kunsthaus Zurich (Switzerland), Museum MARTa Herford (Germany), Parasol Unit Foundation Contemporary Art (London, UK), just to mention a few.
