Research Interests

Safe, stable and sustainable water supply is essential for human health and society. In many developed countries including Japan, social demands for better drinking water quality is increasing while pollution in natural water resources is getting more serious and complex. Many emerging contaminants are hardly removable by conventional water treatment technologies. In addition, how to sustain water supply systems in depopulating society is another big and urgent concern in developed world. Meanwhile in developing countries, water supply is poor in both quantity and quality in many regions. According to the World Health Organization, about 2.5 million lives are lost annually all over the world, which is happening mostly with children under 5 years old in developing countries with no or limited access to safe drinking water. Moreover, climate change adversely affects water resources in quantity and quality, requiring efficient water use globally.
Accordingly, my research interest is on water supply systems and water treatment technologies for safe, stable and sustainable water supply. Among the technologies, water disinfection using UV radiation is particularly of my interest. UV disinfection is promising against chlorine-resistant waterborne parasites, and several other features of UV treatment, such as no formation of harmful by-produces and no negative effects on the odor and taste of water, are advantageous over conventional chlorination. More recently, UV light emitting diode (UV-LED) has been studied intensively, aiming to propose novel reactor design and applications for the innovations in water treatment and supply.
