Research interests

(1)Set theory: Special sets of reals, their regularity, definability, cardinal invariants of the continuum and  I am highly interested in  their appearance in various set-theoretic models, and method of building models; 

(2) Application of (1) to general topology and analysis.

I got grants from  NSFC and did two projects on van Douwen's problem on D-space  and surroundings:

2017/01-2019/12, Topology on elementary submodels and applications to the theory of D-spaces, NSFC 11601443;

2015/01-2015/12, D-spaces and cardinal invariants of the continuum, NSFC 11426188.
