Senja Rummukainen, winner of the XII Turku Cello Competition in 2014, was also a finalist in the Guilhermina Suggia Prize competition in Porto in 2016 and in the Petr Tchaikovsky Competition in St Petersburg in 2019. Her subsequent performances with the Orchestra of the Mariinsky Theatre, the Helsinki Philharmonic, the Tampere Philharmonic, the Tapiola Sinfonietta, the Turku Philharmonic and the Ostrobothnian Chamber Orchestra were acclaimed by critics, colleagues and audiences alike. From 2017 to 2021, Rummukainen played 2nd Principal Cello with the Helsinki Philharmonic, and she is a regular guest playing Principal Cello with the Oslo Philharmonic.

In the 2021–2022 season, Rummukainen made her début with the BBC Symphony Orchestra, performing Elgar’s Cello Concerto under Sakari Oramo at the Barbican Centre in London, and she also appeared as one of the three soloists in Beethoven’s Triple Concerto with the Finnish Radio Symphony Orchestra. She often performs at European festivals and can be heard on the soundtrack of the Aku Louhimies film Odotus [The Wait]. Rummukainen plays a Giovanni Grancino cello (1698) owned by the OP Arts Foundation.
