She is a member of the Parliamentary Assembly of the Council of Europe.
In the circumcision debate in 2012 she strongly opted for an alternative bill to the new circumcision law § 1631d BGB. The alternative bill draft proposed to require a minimum age of 14 years for the circumcision and more specific conditions.
