[curriculum vitae]


I am currently an Alexander von Humboldt Fellow at the Fritz-Haber-Institut der Max-Planck-Gesellschaft, Theory department, Berlin, Germany. My main interest lies in the chemistry and physics of materials, probed via novel ab initio computational methods. By applying state-of-the-art Density-functional Theory (DFT) calculations and the use of statistical thermodynamics and quantum mechanics, simulations of poly-atomic systems can be extrapolated to predict the kinetics of catalytic reactions, the structure and properties of solid and cluster surfaces, reaction energetics, the interactions and reactions of molecules adsorbed on surfaces, and the energetics of defects on surfaces and in the bulk, of the type measured by experiment.
