Loosely speaking, my research deals with the development and application of algorithms enabling rational compound design (RCD), i.e. the virtual identification and optimization of interesting materials/catalysts/drugs, involving areas and topics such as chemical space, (molecular) grand-canonical ensemble (density functional) theory, multi-scaling schemes, statistical mechanics (using electronic, atomistic, coarse-grained & empirical force-fields), molecular dynamics, defects, (molecular) crystals, surface chemistry, nano-objects etc. Here is a little overview talk: Multiscale schemes for the predictive description and virtual engineering of materials . My work is mostly based on combined statistical mechanics and electronic structure theory software, such as CPMD, SeqQuest, VASP, abinit, octopus, LAMMPS, QUANTUM ESPRESSO, and others.
