iTHES (launched in FY2013) is a new framework that integrates the research activities in theoretical science at RIKEN. It promotes interdisciplinary collaborations among theorists in fundamental physics, material science, biological science, computational science and mathematics to unravel the logic of “multi-scale problems” which appear universally in nature from elementary particles to biology and cosmology. Also, iTHES aims to intertwine young theorists in various fields and disciplines and to create an ideal environment for developing new ideas.
