Swiss artist Gilles studied piano and dance at the Geneva Conservatory. He worked for many years as an art and antiques expert in an important Swiss Auction House (Koller Auctions,) where he was director of the Department of Antique Furniture and Decorative Arts. Later, he made his dreams come true by moving to Venice, where he started working as a painter and a set and costume designer for opera houses all over Europe. During this time, he also deepened his knowledge of art history and architecture.

Settled now in Vienna, Gilles continues his artistic activities, works as a lecturer at the University of Music and Performing Arts, and loves unveiling Vienna's rich cultural and artistic heritage to curious travelers.
