| The main emphasis of my work here has been the effect of inertia on different phenomena including spinodal decomposition and drop deformation and break up. | |

The main focus was the application of lattice Boltzmann simulations to
polymer processing. This stimulated my interest in viscoelastic fluids
and lead to the development of a viscoelastic two component model.

| I used the lattice Boltzmann method to show the breakdown of the expected scaling behavior in spinodal decomposition. I also explored drop break-up and spinodal decomposition under shear. I proved rigorously under which circumstances a lattice Boltzmann scheme can obey an H-theorem, promising increased numerical stability. | |

| I developed a model for homogeneous, highly doped semiconductors through which a constant current is forced, and showed that an externally applied magnetic field can lead to chaotic voltage oscillations. I identified a number of transition pathways to chaos, as well as a region with multiple attractors in my numerical simulations. | |
