Self-introduction
I have been working in the field of virology for 35 years. I have been doing basic research on RNA viruses, mainly paramyxoviruses and influenza viruses, and hepatitis B virus, and more recently applied research on disinfectants and antiviral agents. Currently, we are working hard to combat the novel coronavirus. (April 20, 2021)
