Research Overview
Chemotaxis in moving fluid
I am interested in the long-time behavior of the Chemotaxis in a dynamic environment.
Flocking and Swarming in Nature
I am interested in various models describing the flocking behavior in nature, the Cucker-Smale and Motsch-Tadmor models included.
Hydrodynamic Stability
I am interested in the mixing and enhanced dissipation effect of shear flows.

Small Scale Creation
I am interested in small scale creation for SQG equations and the Hou-Luo scenario.
