David's research concerns coarse-grained simulations of charge-regulation and the partitioning of ions in weak polyelectrolyte systems using ESPResSo. These systems include weak polyelectrolyte hydrogels (covalent and reversible) and brushes, but also extend to biologically inspired systems like coarse-grained protein models. The main focus of the research will lie on the simulation of reversible, amphiphilic conetworks which are built up out of four-armed star polymers. Much of the work on these systems will be performed in close collaboration with experimentalists within the DFG Forschergruppe FOR2811.
