Here is a little overview over my research topics. The common theme of these topics is the behaviour of charged systems under out-of-equilibrium conditions.

DNA tranlocation through nanopores

My main research topic is DNA translocation through nanopores. A detailed description of the project can be found here.

Ionic liquid based super capacitors

We work on a better understanding the behaviour on ionic liquids at interfaces, especially under a high applied voltage. My main contribution is an algorithm to take the electrode conductivity (e.g. of graphene) into account in molecular dynamics simulations.

Growth of colloidal crystals

We investigate the growth of colloidal crystal with molecular dynamics simulations. By coupling the particle dynamics with the Lattice Boltzmann Method, we could, for the first time, show that hydrodynamic interactions slow down the growth of colloidal crystals. A manuscript regarding this finding is submitted to Soft Matter.

Solution of the Poisson-Boltzmann Equation

We have developed a novel scheme to solve the Poisson Boltzmann equation with the finite element method including arbitrarily shaped objects with varying dielectric permittivity. In this method, the boundary conditions are determined iteratively. The methods allows for potential dependent surface charges (=charge regulation) and open boundaries.
