Her dissertation was Heisenberg-Gruppen ampler Geradenbündel auf abelschen Varietäten [''[[Heisenberg group]]s of ample line bundles on abelian varieties], and her doctoral advisor was Herbert Lange.
She worked as a research assistant at the University Erlangen-Nürnberg, earning her habilitation there in 1994, until in 2001 she was given a chair in complex analysis at Johannes Gutenberg University Mainz. She returned to Erlangen–Nuremberg as a lecturer in 2003.
