Research interests

I study fluid dynamics and orbital dynamics applied in geophysics and astrophysics, e.g., star, planet, accretion disk, and their interactions. I prefer the pen-and-paper working style, e.g., order-of-magnitude estimations, analytical, semi-analytical and small-scale numerical calculations.
