We investigate the physicochemical properties and heterogeneous chemical processes of atmospheric aerosols based on field and laboratory experiments and assess their relevance to climate processes (e.g., cloud and precipitation processes) in the atmosphere.
Our research subjects include the following:
Hygroscopic property and cloud condensation nucleus activity of atmoshperic aerosol particles
Chemical characteristics of atmospheric organic aerosol components
Heterogeneous/multiphase reactions (ozonolysis and reactions involving gaseous aldehydes)
Some of our researches are based on both wet chemistry (solvent extraction) and dry chemistry (analysis of physico-chemical properties). Combining these two approaches, we seek to better understand the properties of atmospheric aerosol particles. Alternatevely, we also persue advanced on-line aerosol measurements to analyze the particle properties based on physics- and chemistry-based techniques.
