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 and genotyping of human enteric viruses in environmental water. In 2009 he got a tenure position (Associate Professor) at Hokkaido University, Sapporo, Japan, and managed a team of water and public health reasearchers, 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, mathematical optimization of water systems, and causal inference among factors related to WaSH and human health.
