Research Pursuits 【 display / non-display 】

  • In my research on ultraviolet (UV) disinfection mechanisms, I have been working to elucidate the mode of action by combining experimental techniques using synthetic DNA with molecular structure simulations. Building on these findings, I developed a novel method for evaluating the disinfection efficacy of UV treatment, for which I obtained a patent.

    In addition, my research on decentralized wastewater treatment focuses primarily on Southeast Asia, particularly Sri Lanka. There, I have investigated the mismatch between the increasing prevalence of flush toilets and the continued use of non-flush-type decentralized wastewater treatment systems, which poses a risk of pathogenic microorganisms spreading to surrounding water environments and soil. Through on-site field surveys, I aim to understand the local conditions and propose appropriate treatment systems and maintenance methods tailored to each context.

Educational Pursuits 【 display / non-display 】

  • I am in charge of specialized lectures on water treatment and water environmental engineering, as well as related practical courses in environmental health science and chemical experiments. As part of my supervision for undergraduate theses, master's theses, and doctoral dissertations, I hold weekly laboratory seminars to regularly monitor research progress and provide guidance as needed. Current thesis topics mainly focus on UV disinfection and decentralized wastewater treatment. I also actively encourage students to conduct field research abroad.

Future Research Plans, Research Prospects, and Joint Research Potential 【 display / non-display 】

  • By advancing the elucidation of the mechanisms of UV disinfection, it will become possible to promptly propose appropriate disinfection methods even against newly emerging pathogens. The newly developed evaluation method using synthetic DNA significantly reduces the time required to assess disinfection efficacy - from over a day with conventional methods to just a few hours - allows for accurate evaluation of UV effectiveness against a wide range of pathogens. To put this method into practical use, further technological development is required to adapt it for large-scale systems and applications in air disinfection. I aim to address these challenges through collaborative research. With regard to decentralized wastewater treatment, I am focusing on Sri Lanka as a primary target region. I am working on proposing methods that can be easily implemented in the field while effectively controlling pathogen-related risks. Preparations are underway for international collaborative research involving local universities and municipalities.
