Isabel Charisius is a classical violist and an academic teacher.
She was a member of the Alban Berg Quartett and a teacher at the universities of music of Cologne and Berlin.
She was the viola player of the Alban Berg Quartett from 2005, after the death of Thomas Kakuska and upon his wish, until its dissolution.
[2][3] A concert in London's Queen Elizabeth Hall in 2008 with quartets by Haydn, Berg and Beethoven received a review mentioning: "When Charisius was allowed the bass-line, as in some moments in the slow movement of the Haydn, she produced a magical, burnished sound like liquid gold".
She has been a teacher of viola and chamber music at the Hochschule Luzern.
