Research Summary

Yasunori Ichihashi

Over billions of years, organisms have evolved and adapted to their environments. Humans harnessed this natural ingenuity by inventing agriculture, leveraging life's mechanisms to produce food. Yet, recent excessive interventions in ecosystems have led to numerous environmental issues. Instead of dominating nature, our aim is to harmonize with it by understanding and engineering the intricate soil-plant-microbe systems at a systemic level. By utilizing real-world data from agricultural and natural environments and employing high-performance computing, our convergence science aims to contribute innovative solutions to environmental challenges.
