In 1992, he graduated from the State Higher School of Visual Arts in Gdańsk (currently the Academy of Fine Arts), graduating from the atelier of Professor Edward Sitek. In 1994, he was awarded the prestigious Pollock-Krasner Foundation Inc. scholarship. From 1998 to 2013, the artist worked in Canada, where he settled, as he says, 'in search of big trees'. He received financial support for his projects the so-called Emerging Artist Grant and Exhibition Assistance Grant from the Canada Council and the Ontario Arts Council. In 1999, he was a resident artist at the Vermont Studio Centre for a month. Litviniuk's work was awarded a special prize from the Fondo Nacional de las Artes, Buenos Aires, and first prize at the Flur 2001 Vogtlandisches Holzbildhauer Symposium in Germany. In 2005. Litwiniuk had a solo exhibition Open Concept at Thames Art Gallery in Chatham/Ontario.

Wood is his favourite creative material. He does not carve wood, but cuts it, creating geometric shapes of various sizes, from large to small, which he has been reproducing for years and which have become his trademark. The artist seems to be in dialogue with nature; he is interested in the 'anatomy of wood', its structure, mass, volume. By opening a tree, he shows something that is hidden, invisible, forgotten, ignored inside the tree. Litviniuk's sculptures have their own existence and identity. They are like large wooden caterpillars divided into segments or forest geometric constructions composed of precisely fitting elements. The artist's sculptures naturally interact with the landscape becoming an integral part of it. In addition to wood, his primary medium, the artist also works in stone, but he has also used snow, ice, water, grass, sprouting seeds and earth.

The artist's works owe their enormous impact to the large scale in which they are made, as well as their apparent simplicity of focusing on the materiality of the solid and not hiding the traces of the creative process. Located in the public spaces of Toronto and the surrounding area, placed in friends' gardens and subjected to temperatures, Litwiniuk's works, having their own existence and identity, are slowly changing to blend into the landscape.

Litwiniuk has presented his works in exhibitions in: Switzerland, South Korea, Germany, Argentina, Finland, India, Cyprus, Canada and Poland. For several years, the artist has been living in Poland, where he continues his creative activity. In 2016, he took part in the sixth edition of the Landart Festival on the Bug River, where he realised The Gate project. In the same year, at the Konfrontacje Sztuki competition at Warsaw's Test Gallery, the artist was awarded the Prize of the Rector of the Academy of Fine Arts in Warsaw. In 2017, the artist prepared the retrospective exhibition Open System at EL Gallery in Elbląg. From December 2017 to January 2019, Ryszard Litwiniuk's solo exhibition Etalon took place at Gallery 10 GGM in Gdańsk. The artist's sculptures can be found in public spaces and private collections in many countries in Western Europe, Canada, the United States, Argentina and Poland.

Work in catalogue
Ryszard Litwiniuk, 'Transition', 2010, wood, diameter: 70 cm, length approx. 4 m. Made of cut wooden segments, precisely fitted together, the caterpillar sculpture blends into the landscape and coexists with it. The large scale of the sculpture is impressive. The artist moves on the borderline between figurativism and abstractionism. He operates a maximum of synthesis, simplification and geometry in the construction of his sculptures, which brings him close to the syntheticism represented by Constantin Brancusi.
