My main fields of research are dynamical, mechanical and electronic properties of crystalline materials investigated with computational quantum mechanical methods. Most of my work is concerned with two groups of materials: minerals and nanostructures.
If you would like to get some of my papers in electronic form feel free to ask. Due to the fact that you have to give up your copyright to publish anything I cannot just post my own work on the page...
