Dr. Matsuyama has been with LPL since 2011. His research is focused on understanding the formation and evolution of solar system planets and planetary satellites, with an emphasis on the connections between rotational dynamics, orbital dynamics, and interior structure. 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) characterization of the thermal and orbital evolution of icy satellites, with particular emphasis on determining the long-term survivability of their subsurface oceans.
