The artist Irena Jadelo-Katarskė, who is sometimes called a "Renaissance human", has a wide range of activities covering various disciplines. Born in Vilnius, she is not indifferent to the uniqueness of the Old Town, where different styles, cultures and philosophies intertwine. She learned to notice the beauty in the diversity of the surrounding world and integrate elements of various fields into her work. Having become acquainted with the masterpieces of famous creators, she wanted to create something that would last a long time and something that would have value and meaning.

Having studied arts at the Justinas Vienožinskis Art School in Vilnius and the Vilnius Academy of Arts, she developed skills not only in the fields of fine arts, but also in the fields of design.
She received an art award for a work exhibited at the International Graphic Biennial in Poland. Her talent was noticed in the Young Designers Competition (finalist). As a fashion designer, she created not only author's projects that were presented at various events and on television, but also contributed to the creation of the Italian film.
Twice qualified for the national stage of the Language and Literature Olympiad and taken the second place in an international literature competition, the artist is still not indifferent to this form of creativity and is engaged in writing various texts.
A photo of her painting was printed on the cover of an art calendar in Poland (publisher "Apostolicum"), and later appeared in the British art magazime "Tribe. International Creative Arts Magazine".

The artist participated in international projects. Her illustrations presenting "Chanel" and "Valentino" fashion collections were selected and published by "Draw a Dot", curated by Marcus Kan, a fashion illustrator agent who collaborates with famous brands in the world's fashion industry.

Since 2008, the artist's creation has been positioned as the brand "IJK Design Gallery". She creates complex design and art solutions for brands, spaces, and personal projects. She draws pictures and illustrations, creates objects (jewelry, accessories, interior details, paper products), graphic design, branding and corporate identities, writes texts. Her illustrations and graphic design decorate postcards, invitations, publications and websites, while her paintings, murals and installations adorn not only private houses in various corners of the world, but also hotel spaces.

Since 2020, the artist’s work has expanded to include an experimental art project that restores areas beyond the city, shapes the landscape, and transforms buildings, based on local history and vegetation characteristics, and using sustainable solutions.

In 2026, the artist presented an interdisciplinary, immersive creation that combines literary texts and interactive visual art collections designed for practices.

She is a conceptual cross-cultural creator. She explores themes of psychology and philosophy, ways of thinking and living in various spaces, and the cultural heritage of different countries. These elements are reflected in her work and lend it a distinctive quality and uniqueness.
