Research Interests

Dr. Chan's research pertains to aerosol chemistry, air pollution and the source identificationand chemical and physical characterization of atmospheric particulate matter, andunderstanding the chemical pathways involved in the formation of secondary inorganic andorganic particulate matter (PM) from sources such as cooking, traffic, biomass burning, dust,and ship emissions. His research employs both laboratory and field measurements using asuite of aerosol instrumentation techniques such as aerosol mass spectroscopy and offlinecharacterization. Current research includes atmospheric aging of PM via photochemistry ofparticulate nitrate photolysis, photosensitization reactions and chlorine chemistry. ​
