[Monthly Spotlight] is focusing on a researcher to introduce his/her research.
Exploring a New Gravitational Theory ~ Exploring the Origin of the Accelerating Expansion of the Universe ~
Research Topic
Comprehensive studies of cosmology based on gravitational theories
The fact that the universe is undergoing a phase of an accelerated expansion raises the most challenging problem in the golden era of the precision cosmology, and a number of attempts to explain the origin of the present cosmic acceleration have been proposed over the past decade. My research lies at comprehensive studies of gravitational theories and its application to theoretical and observational cosmology.
