Welcome to my web page. I am a Postdoctoral Fellow working at the Canadian Institute for Theoretical Astrophysics (CITA), University of Toronto. I received my D.Phil. in Theoretical Physics from the University of Oxford in 2022 with a thesis titled "Probing dark matter with resonant dynamics of the Galactic bar" supervised by Prof. Ralph Schönrich. I am originally from Japan where I earned my Bachelor's (2016) and Master's (2018) at the Tokyo Institute of Technology.

I am interested in the dynamics of self-gravitating systems, in particular, galaxies. My current research aims at developing theories of dynamical friction on galactic substructures to constrain the nature and phase-space distribution of dark matter. The main tools I employ are perturbation theory, kinetic theory, and N-body simulations.
