I plan to recruit graduate students and postdocs for these projects.

Students with the background of mathematics, physics, fluid mechanics, astronomy or geophysics are welcome to contact me. The projects are not limited to the above ones and you are encouraged to propose your own ideas.

Research Interests

My research interests are fluid mechanics applied to geophysics and astrophysics. For example, how the Earth's magnetic fields are generated and evolve, how tides in binary stars work, why proto-planetary or black hole disks become unstable, how turbulence behaves in the presence of rotation or stratification or magnetic fields, etc. To understand these physical problems, some mathematical equations need to be solved, and the methods involve analytical, semi-analytical and small-scale numerical calculations. Below are some objects that I study (from left to right: Earth's magnetic fields, Jupiter's red spot, stellar interior, tides in binary stars, and disk accretion).
