A prize winner in the British Contemporary Piano Competition, Karis's solo recitals feature works from the twentieth century to the present day, which she enjoys juxtaposing with earlier repertoire. She was a UK finalist for the European Music for Youth Piano Prize, for which she made her Purcell Room debut, and she has given concerts in many of the UK's principal venues, including St. John's Smith Square and the Queen Elizabeth Hall, as well as performing internationally.
With an on-going interest in working with multimedia, performances have included concerts at the De Monfort University Cultural Exchanges Festival, UHArts Mayfest and Transitio Mx Festival of Electronic Arts and Video, Mexico City. She composed the score for live piano for an award winning silent film Dogged, an experimental short, written and directed by Jo Shaw (Red Crow Productions), and as a recipient of the Sir Mark Turner Memorial Scholarship, she has been an artist in residence at the Banff Centre, Canada.
Taking her first piano lessons at the age of nine, Karis went on to receive a scholarship for entry to Birmingham Conservatoire where she studied piano with Malcolm Wilson. She then took piano lessons at the Guildhall School of Music and Drama with Susan Alexander Max and was awarded an MA in Music Performance from City University.
Retaining a keen interest in contemporary works, Karis has collaborated with composers and groups in a variety of projects. These include concerts with B.E.A.S.T. (Birmingham Electro-Acoustic Sound Theatre) and The Music Collection as well as on-stage performances of music for cello and piano commissioned for choreographer Charles Linehan's production of Rialto. She has recorded works by Andrew Hugill for the CD 'Pataphysical Piano as well as pieces by British composers Cornelius Cardew, Howard Skempton, Dave Smith and Gabriel Jackson for a CD of solo piano works, Images and Impressions, released by UH Recordings.
Karis is also an examiner for the Associated Board of the Royal Schools of Music. She has taught piano at the Centre for Young Musicians, London, she has been a lecturer for the Open University and she has given workshops for educational institutes: past events have included performance master-classes in schools and universities as well as lecture-recitals for Workers' Educational Association, in Derby Cathedral, and Birkbeck College, at Wigmore Hall.
