He spent his adolescence in Saint-Etienne and then in Belgium. He studied art at the Saint Luc Institute in Tournai, and then once he graduated, he came back to Saint-Etienne to study desgin at the Superior School of Fine Arts. He currently lives and works in the area of Rhône-Alpes. He evolved in a figurative universe in which he found a predilection for urban subjects. On the canvas, Jean-Baptiste Lyonnet questions himself about space, the strength of elements, the architecture of the cities. He tries to transcribe the mood of the cities where he has lived: Paris, Lyon, Beirut. With his brushes, the city is captured but also transformed, sometimes even to abstraction. Jean-Baptiste Lyonnet exhibits his work regularly in France. His pieces have also been selected for group exhibitions in Dubai and Madrid.
