Painter

Member of the East-Helsinki Art Society, The Finnish Painters' Union , and The Artists' Association of Finland.

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. Some recent paintings can be seen on the thumbnails below, or by clicking on the titles.

Some recent art shows:
   Galleria BE'19, Helsinki, March 1997.
   Euroart'97 in Barcelona, September 26-28, 1997..
