Regional air pollution and global climate change are critical challenges to the whole human society, and impact profoundly on economy and lives of human beings. One of most important uncertainties in the relevant researches depends on the accuracy of the source estimations on major air pollutants and their precursors. My long-range goal is to pursue a career in academia as a ‘life-minded’ environmental scientist who understands how the air quality varies on both regional and global scales and how our lives are thereby affected. In the previous researches, I integrated laboratory, outfield, airborne and satellite observations to quantitively estimate multi-scale Volatile Organic Compounds (VOCs) and Nitrogen Oxides (NOx) emissions, and investigated their impacts with numerical modeling. At present I am interested in the sensitivity of air quality and climate change on VOC emissions, and processes controlling the Biosphere-Atmosphere interactions.
