Research Interest
My scientific interest is on the role of organisms in marine ecosystem
dynamics and biogeochemical cycles. I have been studied biology and ecology
of copepod, beautiful creature in marine ecosystem, but also working on
variety of marine organisms from virus to whales. The essential aim of
my studies is to understand the processes and mechanisms of marine ecosystem
response to natural and anthropogenic perturbations. Recent research topics
are:
• Developing new ocean provinces respect to geochemistry and biogeography(Link)
• The role of Kuroshio on the structure of marine ecosystem and fisheries
production(Link)
• Mechanism of fish stock fluctuation responding to climate change.(Link)
• The role of zooplankton on biological pump
• The role of iron on marine food-web dynamics and biogeochemical cycles
