I attended the HRWM group meeting for the first time in Mallorca, Spain in 1996. Since then, the HRWM group has continued to be the most productive and interesting platform in my research carrier, especially through its series of symposia. In recent decades there have been so many advances within the HRWM study area, including molecular techniques, QMRA, microbial source tracking, etc. I am excited that we are now at a stage in this era where the outcomes of those developments are gradually being implemented into real societies. I contributed to the International Symposium on HRWM (WaterMicro 2007) in Tokyo as a member of the local organizing committee, and served as the HRWM group secretary from 2009 to 2013. Now, I am more than happy for the opportunity to contribute to the group further as its vice chair. I would like to maintain the traditional virtues of our group while attracting young members and enhancing international diversity.

Dr. Daisuke Sano, Professor of Environmental Water Quality at Tohoku University, Japan, completed his PhD. in March 2003 at Tohoku University. In the PhD study, he discovered bacterial proteins that can interact with human virus particles from activated sludge microorganisms. Then, he took a Post-Doctoral Fellowship at Tohoku University (2003-2007) and University of Barcelona, Spain (2007-2009). As a postdoctoral fellow, he was involved in multiple projects with regards to the transmission pathway of norovirus, culture-independent evaluation of virus infectivity (3) and genotyping of human enteric viruses in environmental water. Then he got a tenure position (Associate Professor) at Hokkaido University, Sapporo, Japan, since 2009 and was managing a team of water and public health study, and discovered histo-blood group antigen-positive bacteria that could specifically capture human noroviruses. He moved back to Tohoku University in 2017 and is responsible for the research and supervision of international and domestic projects in the field of water and public health. Particularly, he is currently interested in the statistical modeling of enteric pathogens disinfection/removal, antibiotic resistance and water, and the impact of chemical contaminants on ecosystems.
