Current Research

  • Atmospheric chemistry of biomass burning compounds (mainly furan and phenol derivatives). The studies include measurements of the rate coefficients for the reactions with OH radical, Cl atom and measurements of UV absorption spectra, photolysis quantum yields to estimate atmospheric lifetimes. Reaction product studies are also being carried out in order to understand the details of the reaction mechanism.
  • Measurement of the infrared spectra, atmospheric lifetimes and global warming potentials (GWPs) of perfluorinated compounds to assess their suitability as replacements of the CFCs and Halon compounds.
  • Atmospheric chemistry of halogenated compounds found in the arctic region.
