About

I am a cosmologist at the University of Tokyo’s Kavli Institute for the Physics and Mathematics of the Universe.

My work focuses on learning about the physics of the early universe from cosmology. This means studying how high-energy processes in the early universe can lead to things we can measure today, and conversely how things we measure in the sky constrain the form of high-energy physics.

In particular, I have worked extensively on how the physics and symmetries of cosmic inflation constrain the ways in which it can produce observable relics like black holes, gravitational waves, and non-Gaussianity. I have studied the behavior and role of the Higgs field in the early universe, and the imprints of axions as a dark matter candidate.

I also really enjoy playing with language and languages. I speak English and French natively, and would be grateful for any help with my Japanese.

I completed my PhD under the guidance of Wayne Hu at the University of Chicago’s Kavli Institute for Cosmological Physics, and my undergraduate studies at the University of Pennsylvania were supervised by Adam Lidz.
