Laboratory Introduction

1.Research on controlling infectious diseases: Our research themes are relevant, not only in the basic science, but also in the field of infectious diseases response and preparedness.
2.Field-based Studies: We believe in looking at an infectious disease from different perspectives for its better management. We are therefore conducting not only laboratory-based studies, but also field studies based in the community, public health centers, clinical set-ups, and even in the environment.
3.Conducting researches in broader perspective: We are always open to conduct researches on any viral infectious diseases in different perspectives for better understanding on the evolution of emerging and reemerging infectious diseases. We are therefore not always focused on our expertise to a particular infectious disease; we rather respond to a wide variety of infectious diseases depending on their public health importance.
4.Research on global perspectives: We are conducting collaborating studies in Asia, Africa and South America. We also contribute to the emergency response and preparedness activities of the World Health Organization and other international organizations. In addition, we are also collaborating with domestic institutions and universities. We believe in the idea that the spread of infectious agents is not limited to any geographical boundaries, thus, there are no borders for conducting research on infectious diseases as well.
