Shuntaro Aoki

Hello,
My name is Shuntaro Aoki, and I am a researcher at RIKEN iTHEMS. My primary areas of expertise are particle physics and cosmology, with a special focus on the early universe.

I obtained my PhD from Waseda University in 2018 and worked as a lecturer at the same institution until March 2021. In April 2021, I joined Chung-Ang University in Korea, where I worked until August 2022. Subsequently, I continued my research at the Institute for Basic Science (Korea) until November 2024, before joining RIKEN iTHEMS in December 2024.

My current research focuses on the cosmological collider program, which aims to uncover new physics beyond the Standard Model through the study of non-Gaussianity in primordial perturbations. These perturbations, believed to have been generated in the early universe at extremely high energies, provide valuable insights into heavy particles that are inaccessible in terrestrial experiments. Specifically, I have been working on the theoretical aspects of the cosmological collider, such as deriving analytic expressions for correlation functions and exploring particle physics models that predict large "signals" of interest. This research lies at the intersection of cosmology and particle physics, offering exciting implications for both fields.

My long-term goal is to contribute to uncovering high-energy physics through cosmological observations. Ultimately, I aim to deepen our understanding of the universe's fundamental nature and its origins, while fostering new methodologies and collaborative efforts to advance the field.

Beyond research, I enjoy football, fishing, and walking—activities that help me maintain a balanced and creative approach to problem-solving.
