She then studied music theory and composition at the Sibelius Academy and got her diploma in 2000. 1998-99 Wennäkoski studied in the Netherlands with Louis Andriessen.
In 2017 BBC commissioned Wennäkoski an orchestral work Flounce, the premier of which was at the Last Night of the Proms on September 9th, 2017 - Sakari Oramo conducting the BBC Symphony Orchestra.
