h-index: Web of Science (Google Scholar) = 43 (46); m-index ~ 2.3; citations ~ 6000 (7000); ~170 peer reviewed publications

Research Interests

Interaction between organic semiconductors and organic or inorganic substrates (organic nanostructures); interface modifications in organic devices; non-linear optical processes in conjugated molecules; theoretical and experimental investigation of excitation processes in conjugated organic materials; developing strategies for applying techniques going beyond conventional density functional theory to large systems; study the impact of disorder by combining quantum-mechanical modeling with molecular-dynamics simulations.
