Earth Observatory of Singapore

My research is focused on atmospheric chemistry and my research goal is to understand chemical processes in the atmosphere because these processes are relatively important for both global and regional environments.

My current research interests include:

Haze originated from forest burning
Including Singapore, many countries in Southeast Asia are experiencing haze originated from forest burning. Those haze plumes have significant adverse effects on regional environments such as human health and visibility. He is trying to understand emission, aging, and potential impacts on environments of haze plume by conducting atmospheric observation and laboratory experiments.

Atmospheric chemistry in the tropical region
Tropical rain forest is a globally important source of atmospheric trace gas species. Chemical reactions of those species form some key materials for the global climate such as nuclei of cloud droplets. Human activities in tropical areas, including Southeast Asia, are changing those naturally occurring chemistry. For instance, emission of trace gas species from plantation is significantly different from original tropical rainforests, altering chemistry in the atmosphere. Enhanced human activity in the tropical region provides a higher chance for anthropogenic species to react with biogenic origin compounds, perturbing original chemistry in the atmosphere. He is interested in quantifying how interaction between human activities and tropical environment changes chemistry in the atmosphere, and how the perturbation affects the global climate.
