- Atmospheric chemistry of biomass burning related compounds as part of the laboratory component of NOAA's FIREX mission. The studies include measurements of the rate coefficients of the gas phase reactions of biomass burning compounds (mainly furan and phenol derivatives) with OH radical, Cl atom as well as assessing photolysis decay rates (by recording the photolysis quantum yields, UV absorption spectra) to estimate the atmospheric lifetime. Identification and measurement of the yields of the reaction products are carried out for in-depth understanding of the reaction mechanism.
- Perfluorinated organic compounds: Assessment of their suitability as replacements of CFCs and Halon compounds by evaluating atmospheric lifetimes, infrared spectra, radiative efficiencies and global warming potentials (GWPs).
- Photochemistry of DMS (dimethyl sulfide) derivative in the context of SO2 production.
- Atmospheric chemistry of some halogenated organic compounds found recently in the arctic region.
