Irén Seleljo was born in 1987 in Uzhhorod, Transcarpathia. She began her piano studies with her mother Alexandra Seleljo at the music school in Bonyhád, and continued her studies at the Szent István Király Secondary School of Music in Budapest, in the class of Erzsébet Kőrösiné Belák. In 2006 she was accepted to the Liszt Academy of Music in Budapest, where she continued her studies with Attila Némethy and István Gulyás. In 2008 she won a scholarship to Bard College (Annandale-on-Hudson, USA), where her piano teacher was Jeremy Denk. In 2011, after obtaining her Master’s degree in Piano and Teaching, she was admitted to the Vienna Conservatory Wien Privatuniversität, Vienna, to study piano accompaniment with Denise Benda.

Her love of chamber music was evident from an early age and still plays an important role in her life. She currently performs as a member of various ensembles (Seleljo Duo, Duonarchie, Trio di Vienna). Her repertoire ranges from baroque to contemporary music, with several national and international premieres to her name.

In recent years Irén Seleljo has performed in Austria, Slovenia, Italy, Spain, France, Romania, Slovenia and Chile. In 2013 she released her first recording, Art of Duo (on the Col legno label), on which she recorded the classics of the saxophone repertoire with the Austrian saxophonist Gerald Preinfalk. Many of Seleljo Duo's concerts have been recorded by Bartók Radio. Irén Seleljo currently lives in Vienna and teaches at the Musik und Kunst Privatuniversität der Stadt Wien and the Kunstuniversität Graz.
