Research Activities
Molecular analysis of interactions among plants, microbes and insects:
We are attempting to elucidate the complex interactions between plants, plant-infecting microbes and microbe-transmissible and plant-eating insects at the molecular level.

Future Plan
We are focusing on the biology of plant DNA viruses, their host plants and their vector insects. By using molecular and cellular approaches, and from an evolutionary point-of-view, we expect to be able to elucidate the natural history of their complex interactions. The information obtained from these studies will contribute not only to widening our understanding of nature but also to solving global problems such as plant disease control and food security.
Messages to Students
I hope that you will try to be a scientist, which I believe is a sacred profession. We human beings depend upon global resources, both concrete (such as food and energy) and abstract (such as philosophy), to live our lives. Politicians and businessmen can "redistribute" the current resources, but only scientists can "create and increase" them.
