An autodidact painter, I have been exhibiting my art since 1971, mainly in Finland, but also in Vienna, Geneva, Tokyo, Barcelona, New York, Spoleto (Italy), and Padova. I paint on paper, cardboard an canvas, often assembling collages from own material, such as acrylics on paper or glass fiber canvas. Then the composition is a two-step process: paint and cut-out. My motives are generally abstract, although various forms may remind the spectator of real objects. I choose quite neutral titles so as not to hinder the free fantasy of the spectator. Occasionally my motives are inspired by my science; more often the titles allude to science even if the motive does not. I often sign my paintings with two Chinese seals, one being a phonetic transcription of "Matts" in Chinese, the other being my monogram MR.
