Appointed to "International Wastewater-based Epidemiology" Program (Drs. Kasuga & Liu)
As of April 1st, Project Assoc. Prof. Ikuro KASUGA (RCAST/concurrent) and Project Asst. Prof. Miaomiao LIU (previously project researcher of Dept. Urban Engineering) have been appointed to the "International Wastewater-based Epidemiology" Corporate Sponsored Research Program, RECWET. Member information
Wastewater-based epidemiology (WBE) utilizes the features of sewage infrastructure, where pathogens like viruses discharged from infected individuals accumulate in wastewater treatment plants. WBE provides a potent avenue for gathering public health data, facilitating early detection of disease outbreaks and comprehension of infection trends. Since its establishment in March 2024, the International Wastewater-based Epidemiology Program has been pioneering in the field of "wastewater-based epidemiology" and aiming to contribute to the establishment of resilient societies against infectious diseases through the implementation of WBE both domestically and internationally.- 2024/03/01
"International Wastewater-based Epidemiology" Program launched (Project Profs. Katayama & Kitajima)
The "International Wastewater-based Epidemiology" Corporate Sponsored Research Program has been launched at RECWET. As of March 1st, Project Prof. Hiroyuki Katayama (Dept. Urban Engineering/concurrent), Project Prof. Masaaki Kitajima (previously Assoc. Prof. of Hokkaido University) and Project researcher Vu Duc Canh (previously Dept. Urban Engineering) have been appointed (photos are only faculty's). See the member details.
