Research Interest
My research interest is in an air quality change in PM10 and cause of occurrence of high PM10 phenomena. Particularly, I've focused on the meteorological factors associated the phenomena through the analysis of satellite-retrieved and ground based observation data. Currently, I'm studying about the quantitative influence of trans-boundary air pollutants from China using CMAQ modeling results.
