An autodidact painter, I have been exhibiting my art since 1983, mainly in Finland, but also in Vienna, Geneva, Tokyo, Barcelona, New York, Spoleto (Italy), and Padova. I have often assembled collages from own material, such as acrylics on paper or glass fiber canvas. Then the composition is a two-step process. 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. The background to this homepage uses repetitively a 1997 painting which is not a collage. I often sign my paintings with two Chinese seals, one being a phonetic transcription of "Matts" in Chinese, the other being my monogram MR.
