Research Interests：

1. Research on Material Cycling in Various Ecosystems in Tropical region
2. Human Impacts on Material Cycling in Tropical Forests and Peatlands
3. Effects of Land Use Changes on River water quality and quantity

Research Overview：

Based on the “Research on Material Cycling in Various Ecosystems in Tropical region”, I have conducted the formation of research hub which are related to human oriented environmental issues in Indonesia and Malaysia. I have also started to conduct the researches with some local counterparts.
In Riau province, Sumatra, Indonesia, I started the biogeochemical research at degraded peatland forest ecosystems for evaluating the difference in environmental condition between various land uses. Also I’m now training the local students about the researches on carbon dioxide exchange between the soil and the atmosphere and the water chemistry in water discharged from peatland area at the CSEAS’s local field stations. I also contributed to sign an agreement for research collaboration with Indonesian Research Institute. This research is supported by JSPS kakenhi (Supporting start for younger researcher.). In Malaysia, I have conducted the researches on Greenhouse gases (carbon dioxide, methane, and nitrous oxide) dynamics and the river water quality survey of non-peat river water in Peninsular Malaysia. In Taiwan, I’m conducting the collaborative research with Academia Cinica, Taiwan on food-web analyses in Fei-Tsui reservoir which is used for drinking water of Taipei city residence.
