I am an Associate Professor of the Asian School of the Environment at Nanyang Technological University in Singapore. By training, I am an atmospheric scientist and a modeler. To develop a sustainable environment, my research devotes to improve the knowledge of climate change and air quality, and the influences on human health and planetary health. Besides research, I strive to contribute to various government committees and professional associations, aiming at transferring my developed knowledge through research to the society. I serve as the member of the Global Air Pollution and Health - Technical Advisory Group (GAPH-TAG) of the World Health Organization (WHO), and also serve as the invited committee member of the National Advisory Board on Atmospheric Science Discipline in Higher Education, the Ministry of Education of China. Additionally, I contribute to the editorial boards of international peer-review journals including Scientific Reports (Nature) and Atmosphere.

Research Interests:

My research focuses on the interactions between climate and air quality, and the resultant impacts on public health and ecosystem. My on-going research is to develop, advance and utilize the state-of-the-art multi-scale atmospheric models, along with measurement and statistical approaches, to understand the mechanisms that drive the climate-air quality interactions, and evaluate the impacts on human exposure, mosquito abundance and soil acidity. Particular interests are in investigating air quality impacts of sectoral emissions and transboundary air pollution at multiple spatial scales, studying regional climate change due to land-use changes and global climate change, and evaluating and quantifying the effects of air pollution on respiratory and cardiovascular diseases. My research also assesses and develops emission control scenarios to provide scientific-based policy solutions for a sustainable environment in present and future years.
