Ryuho Kataoka is challenging a high-speed imaging of aurora to visualize fundamental nonlinear processes in space plasma. Major research interests include the space weather forecast, extreme space weather, and space climate. Nebula Winter hypothesis was proposed to explain the catastrophes as possible consequences of the worst space environment in our galaxy.
