Research Focus
My work is mainly focused on the experimental aerosol study. I look into the chemical reaction and Secondary Organic Aerosol (SOA) formation using a Potential Aerosol Mass (PAM) chamber, which can simulate atmospheric oxidation processes on timescales ranging from a day to several days in a few minutes in the laboratory. In the measurement, all precursor gases are rapidly oxidized with extreme amounts of oxidants to low volatility compounds, resulting in the aerosol formation. Both off-line measurement (filter collection to GC analysis) and real-time measurement will be used in the experiments.
