Research Description

The new influenza A (H1N1) virus and the new coronavirus (SARS-CoV-2) emerged in 2009 and 2019, respectively, and caused severe respiratory illness in humans worldwide. The pandemic of these infectious diseases resulted in the significant damage to public health. In addition to the massive death of virus-infected people, the COVID-19 pandemic and related lockdown restricted social activities worldwide. Most of emerging infectious diseases that have occurred in recent years, including the new influenza and COVID-19, are zoonosis. These zoonotic diseases are caused by pathogens have been transmitted from livestock and wildlife to humans, and zoonosis control is absolutely essential for the development of. inclusive society between humans and animals. The control of infectious disease in food animals is important to improve animal health and productivity in the livestock industry as well as to promote food safety for human health and welfare.
In my research, I am conducting the epidemiological surveillance of various infectious diseases to clarify the distribution of pathogens such as viruses and bacteria and the prevalence of diseases in humans and animals. The aim of my research is to prevent the future outbreaks of zoonotic diseases and control epidemiology. Based on the wild-type pathogens obtained through the field-work, I will promote basic research for the development of new diagnostic methods, vaccines, and therapeutic agents. Using molecular biological method, I would like to establish new strategy for infectious disease control.

About TUAT's tenure-track program

The tenure-track program promotes the research activity of young researchers by providing the chance of permanent position and start-up budget. This is very attractive and helpful for young researchers. Additionally, I can receive various supports and advices from mentors and other professors, and work on education and research without any worries.

Future aspirations

I really appreciate that our university and professors have provided me the opportunities of education and research. I would like to work on research together with students, and contribute the development of my specialized field.
