Isamu Matsuyama

Isamu Matsuyama is a Professor at the University of Arizona, affiliated with the Lunar and Planetary Laboratory (LPL) since 2011. His research focuses on planetary interiors and evolution, with specific emphasis on lunar and outer solar system bodies. He holds a Ph.D. from the University of Toronto (2005) and contributes to theoretical models interpreting planetary observations.

• Education: Ph.D., 2005, University of Toronto

Dr. Matsuyama's research explores the thermal and orbital evolution of planetary bodies, including the Moon's fossil figure, tidal dynamics in ocean worlds like Europa and Ganymede, and the long-term survival of subsurface oceans in icy satellites. His work integrates theoretical modeling with spacecraft data from missions like GRAIL and proposed missions such as the Io Volcano Observer (IVO).

Recent publications highlight advancements in tidal tomography, thin-shell dynamics, and rheological modeling, with a focus on 2025-2024 high-impact studies in Nature and Geophysical Research Letters. These works span lunar thermal asymmetry, Callisto's orbital dynamics, and spectral methods for heterogeneous bodies.
