Research areas	Aquatic Chemistry, Analytical Chemistry, Geochemistry, Limnology
Keywords	Lake, River, Sea, Material circulation, Biogeochemistry on Trace Elements
Themes	I have been investigating dynamics of chemical components in the hydrosphere. I also have a great interest in the development of new analytical methods for water quality in lakes and the ocean. We proceed our research with both field observations and laboratory experiments.
