Research

I am working on the gas hydrate, seep and seep sediments, and related geology and geochemistry, fossilized seep deposit.

My current projects include the In situ measurement of seep flux and activity at seep sites, geochemical process of methane at gas vent and hydrate site on the seafloor, controls of gas hydrate formation in South China Sea.
