Xing studied BS and MS at Tsinghua University (mechanics, 98-04) and PhD at Cambridge University (fluid mechanics, 04-08). Before joining INS SJTU in 2015 he worked at ETH Zurich (geophysics, 09-11), Gottingen University (geophysics, 11-13) and Princeton University (astrophysics, 13-15).

Xing’s research is about geophysical and astrophysical fluid dynamics to understand the physics in planetary and stellar interiors, especially rotating magnetohydrodynamics (MHD) and dynamo theory (i.e. how the magnetic fields of astronomical objects are generated and evolve). The methods of research involve analytical, semi-analytical and small-scale numerical calculations.

Xing plans to recruit one or two PhD students. The two possible projects are listed below.

- Project 1: how Earth’s precession influences the generation and variation of geomagnetic field.
- Project 2: how the waves in planetary and stellar interiors are excited by tides and dissipate through viscosity and Ohmic heating.

Students with the background of mathematics, physics, fluid mechanics, astronomy or geophysics are welcome to contact Xing (see the email address). The PhD projects are not limited to these two. The PhD candidates are encouraged to be initiative to propose their own ideas, and Xing will assist them to fulfill their PhD studies.
