Molecular Genetics, Ecology and Evolution of Symbiotic Interactions

Organisms have evolved to adapt a variety of biotic and abiotic environments on earth over their long evolution time. Symbiosis such as "parasitic", "mutualistic", "predation" are sophisticated phenotypes and indispensable elements to keep the health of each ecosystems.

Devastating problems of ecosystems, such as outbreaks of pests and species extinctions occur when such exquisite balance was disrupted by human activities, and that may easily spread across the borders.

Our laboratory has interest in discovering the new phenomena/ability of organism’s adaptation to the environment. We're trying to understand the mechanisms and evolution of the phenomena/ability by molecular genetics; that would give us a fundamental resolution of the problems that we’re currently facing.
