- Systematic construction of effective nuclear forces linked to realistic interactions, tailored to be used with our state-of-the-art beyond-mean-field variational approaches (VAMPIR).
- Besides nuclear structure and dynamics, problems of nuclear astrophysics, tests of fundamental interactions and symmetries and the exotic phenomena expected near the drip lines. These goals are reached within the European collaborations: NUSTAR (HISPEC-DESPEC), DFG, ISOLDE, ENSAR-THEXO.
