Oleksandr Serdiuk was born in Kharkiv in 1982. He graduated with honours from Kharkiv Art School in 2002 and earned a master’s degree with honours from the Kharkiv State Academy of Design and Arts in 2008, where he studied monumental painting under Viktor Hontarov. After graduating, he began teaching drawing at the academy.
Serdiuk has exhibited since the late 1990s. His work has been shown in Ukraine and abroad, including in Germany, the United Kingdom and Taiwan. He also takes part in plein-air painting programmes. In 2025, he and Volodymyr Nosan presented the exhibition Echoes in Space at Imagine Point gallery in Kyiv. In his figurative compositions, landscapes and still lifes, Serdiuk draws on his training in monumental painting, working with simplified forms and distinct areas of colour.
In 2006, he received a certificate of honour from the National Union of Artists of Ukraine for The First Inhabitants of Sloboda Ukraine. He joined the Union in 2010 and that same year received a silver medal from the National Academy of Arts of Ukraine for his painting A Ballad of the Kobzars. In 2018, he received the Ukrainian state title Honoured Arts Worker of Ukraine.
Following Russia’s full-scale invasion of Ukraine in 2022, Serdiuk moved from Kharkiv to Lviv, where he lives and works.
