I am an Earth system scientist who enjoys exploring the chemical transport of the gases and aerosols in the atmospheric environment. For instance, I investigate the interface of atmospheric sciences and volcanology through studying the physical chemistry of volcanic eruption plumes considering gas-ash-aerosol interactions. This complex transport process essentially modulates the physical and chemical properties of the volcanic ejecta and thus, its impact upon the Earth system. Among other models, I mainly use WRF-Chem to model not only the chemistry and dispersion of volcanic clouds but also the regional air quality. My major research interest is to develop and deploy numerical models to simulate:
