Mr Christopher GAN

Mr Christopher Gan’s research work focuses on atmospheric dispersion aimed at enhancing the understanding and assessment of air pollutant impacts across tropical Southeast Asia. His key interests include dispersion modelling of biomass burning smoke, from emissions to transport and downstream impact on regional air quality. With prior experience as an operational meteorologist, he also has a keen interest in facilitating the transition from research to operations.
