Atmospheric chemistry

Our research:

We are interested in reactions that determine how primary pollutants (e.g., NOx) transform to generate secondary pollutants (e.g., O3, aerosols, etc.) which often have greater impact than primary emissions. In particular, we are interested in gas- and particle-phase chemistry of nitrogen oxides and halogens. 

Our approach:

We develop and use cutting-edge analytical instruments to quantify trace gases at ambient abundant levels. This enables laboratory studies under realistic conditions and also enables us to quantify these directly in ambient air. Results from field measurements are then used to constrain models and assess the importance of the compounds we study.
