Graduate School: Marine biogeochemical cycles|
Biogeochemical cycles of trace metals in the open ocean (2001- present)|
We are studying the biogeochemical processes that control the distribution of trace metals in seawater.

Speciation of trace metals in seawater is not well known.|
We are developing a methodology to reveal the speciation of trace metals in seawater.
|Messages to Students|
I hope to work with those who want to both do experiments in the laboratory and participate the field work.|
Both laboratory and field studies are essential in my research field.
