Research Topics
“Water” is essential for our lives and livelihoods, and also works as a medium of transporting substances on both local and global scales. Therefore, the sustainability of our life and ecosystem can be easily threatened by the excess usage and pollution of water resources.
We are doing education and researches on “water quality control technology (water treatment)” and “relationship between material transport and aquatic ecosystems” to solve or prevent such issues for water resources. We hope to make our society safe, comfortable, and sustainable.
Wastewater to food production: A new wastewater treatment process
In the future world with more increased population, we will need more food and fertilizer. |

Evaluation of the groundwater function for conservation of coastal ecosystems
Seagrass and seaweed meadows are regarded as an important coastal ecosystem for their functions of “ecosystem service”, such as carbon stock and habitats. |
