Research

Decline in dissolved oxygen content of coastal marine environment is plaguing many areas around the globe. Our group focus in understanding the cause of hypoxia in Hong Kong and the South China Sea and providing sounds solution to decision maker to improve the situation. Using a multidisciplinary approach, we aim to understand the linkages between nutrient biogeochemistry, microbial community, physical setting and oxygen cycling.

Nutrient cycling, Hypoxia & Eutrophication

Wetlands are a very dynamic ecosystem where we can observe strong physico-chemical gradient as well as a high biodiversity. Therefore, they represent an ideal location to explore fundamental interactions between sediment geochemistry and microorganisms along redox gradient. Moreover, wetlands are of prime importance to the heavily urbanized region of Hong Kong because of their natural capacity to trap and retain pollutants, nutrients and carbon providing extremely valuable ecosystem services.

Biogeochemistry of wetlands

Geological record can be used as a time-machine to go back to periods of Earth's history that can help us produce new knowledge about fundamental interactions between the ocean, the atmosphere, the cryosphere, and the biosphere that ultimately shape global climate. Our group focus on investigating what drives global ocean circulation over glacial-interglacial timescale to provide insights on the potential near-future impact of ongoing global warming on ocean circulation, primary productivity and oceanic carbon storage.
