My field of expertise is cosmology. My research spans a wide range of topics, including early-universe studies using particle theory (e.g. inflation), dark matter searches, and the formation of large-scale structures. I aim to be a theorist who works in close collaboration with observations and experiments. Recently, I have also been working on low-energy quantum gravity and its experimental verification. Kavli IPMU is my "home institute," where I spent my years as a graduate student and earned my PhD. I am truly delighted to have the opportunity to conduct research at Kavli IPMU once again and look forward to deepening my studies through new challenges and discoveries in this inspiring environment.
