Main areas of research:

  • Transition metal chemistry in heterogeneous catalysis: We explore the mechanistic aspects of heterogeneous thermo-/electro-/photo-catalysts with active centers having d-block metals. We probe, at the atomic/molecular level, the coordination environment, redox & spin states of metal centers, and other structural details of key complexes and intermediates.
  • Organic radical and semiconductor chemistry in the condensed phase: We study the electronic and atomic transfer processes, dynamics of excitons and carriers in redox-active condensed organic matter, such as organic heterogeneous photocatalysts, organic semiconductors, and environmental particulate matter.
  • Advanced magnetic resonance techniques: We develop and apply experimental techniques for Electron Paramagnetic Resonance (EPR) and Dynamic Nuclear Polarization (DNP) spectroscopies. We also model relevant spin systems by theoretical and computational means.
