Andreas Günther


Ich bin seit 01.03.2010 am Zuse-Institut Berlin (ZIB).
Meine aktuelle Homepage finden Sie hier.


Unter Betreuung von Prof. Dr. M. Hinze beschäftigte ich mich mit den DFG SPP 1253-Projekten
- Structure Exploiting Galerkin Schemes for Optimization Problems with PDE Constraints
- Hierarchical Solution Concepts for Flow Control Problems
