Self-introduction
My research focuses on particle cosmology, particularly axions. Through the study of axions, I have explored diverse topics in early-universe physics, including inflation, cosmic birefringence, dark matter, dark energy, topological defects, gravitational waves, and primordial black holes. My goal is to understand how these phenomena leave observable imprints and, ultimately, to clarify the underlying physics of the early universe.
