My field of research is inorganic chemistry and spectroscopy. In-situ and operando spectroscopy, Electron Paramagnetic Resonance spectroscopy, infrared spectroscopy of coordination compounds, bioinorganic molecules and materials.

I work primarily within catalysis: deNOx catalysis, NO oxidation and O2 activation, magnetic and electronic structure determination of catalysts, dynamic nuclear polarization NMR applied to follow reaction intermediates and catalytic mechanisms.

Collaborators are experimental groups at DTU, University of Copenhagen, University of Southern Denmark, Aarhus University and in Spain, Germany, Great Britain and USA.
