Associate Professor
We use computational modelling to probe various chemical processes which are important in the environment, catalysis and nanotechnology. We study small molecules, nano-structures, surfaces or bulk solids, employing electronic structure methods based on Density Functional Theory (DFT) and predict their structures, energies, optical properties etc. We also study electronic transport in molecules and nanostructures to look for systems which can perform molecular electronic functions, like sensing, switching or rectifying. At present, we are interested in theoretical modelling of materials which may have potential application in energy storage devices and exploration of new catalysts for energy conversion, as these problems are at the core of sustainable development.
