Focus of research: Mechanisms of (surface) plasmon-enhanced optical processes in molecules and of reactions undergone by molecules on surfaces of nanoparticles (NPS) in plasmonic NPs-molecules hybrid systems, with focus on the photochemical and the plasmon-mediated reactions; optimization and utilization of methods of molecular spectroscopy based on (surface) plasmon enhanced optical processes, namely SERS (surface-enhanced Raman scattering), SERRS (surface-enhanced resonance Raman scattering), SEL (surface-enhanced luminescence) and SEIRA (surface-enhanced infrared absorption).

Principal research interests: Physical, inorganic and material chemistry, nanoscience, namely plasmonics in conjunction with surface science and molecular spectroscopy.
