Our lab makes a comprehensive understanding for various air pollution and climate change issues and contribute to develop the solutions to handle real world problems. Basic to advanced scientific and engineering approaches are performed to improve the knowledge about the cause of air pollution and climate change and add scientific understanding of complicated earth system. Multi-disciplinary researches are conducted together with many professionals in atmospheric physics/chemistry/engineering, epidemiology, and socio- economic sciences to derive integrated analyses and total solutions to real world problems.
