Specializing in planetary formation theory and planetary exploration, I am actively involved in the development of the next generation of planetary exploration missions from within JAXA. I am involved in the exploration programs of ESA, NASA, and JAXA, and I spend 3-4 months/year at the University of Paris.

Research Interests
Using computer simulations and theoretical methods, I aim to understand the formation and evolutionary processes of various planetary systems, small bodies, and rings (planet formation theory). I also aim to actively maximize the value of planetary exploration missions from a scientific perspective (planetary exploration science).
Mission Involvements
NASA Cassini / JAXA Hayabusa2 / ESA BepiColombo / JAXA MMX / JAXA Next Generation Sample-Return Mission / JAXA OPENS (Japan's first exploration of the outer solar system !?)

Around the snow line, icy pebbles and silicate dust may locally pile-up and
form icy and rocky planetesimals via streaming instability and/or gravitational
instability. We perform 1D diffusion-advection simulations that include the
back-reaction t...

Throughout the history of the solar system, Mars has experienced continuous asteroidal impacts. These impacts have produced impact-generated Mars ejecta, and a fraction of this debris is delivered to Earth as Martian meteorites. Another fraction o...

Phobos and Deimos are the two small moons of Mars. Recent works have shown that they can accrete within an impact-generated disk. However, the detailed structure and initial thermodynamic properties of the disk are poorly understood. In this paper...

Saturn's F ring is a narrow ring of icy particles, located 3,400 km beyond the outer edge of the main ring system. Enigmatically, the F ring is accompanied on either side by two small satellites, Prometheus and Pandora, which are called shepherd s...
