In this thesis, an algorithm to calculate electrostatic interactions in molecular dynamics simulations is extended to include spatial and temporal variations in the dielectric permittivity of the system. The algorithm is implemented, verified, and parallelized. It is then applied to a number of systems containing charged soft matter. Noticeable quantitative and qualitative differences are found between simulations including and excluding dielectric variations. Particularly for the effective charge of colloids, and for the conductivity of polyelectrolytes in aqueous solution, major behavioral changes are shown.
