Dr. Matsuyama is interested in the physics of planetary interiors and evolution, with an emphasis on understanding the processes that led to the extraordinary diversity of the solar system. He develops theoretical models which are used to interpret spacecraft and ground-based observations.

Current research interests involve improving our understanding of (1) the formation and evolution of the Moon by analysis of the global lunar figure, which provides a record of prior orbital and rotational states; and (2) characterize the thermal and orbital evolution of icy satellites, with particular emphasis on determining the long-term survivability of their subsurface oceans.
