Biography
I received my B.S. in Mathematics from Beijing Normal University in 2008. And then I received my Ph.D. in Mathematics from Beijing Normal University in 2013 under the supervision of Prof. Dachun Yang. I joined the faculty at Lanzhou University in 2013, where I was promoted to associate professor in 2016.

Research interests
My research interests fall into harmonic analysis and function spaces. I am particularly interested in real-variable theory of Hardy spaces and BMO spaces, singular integral operators, Riesz transforms associated with second-order elliptic operators and boundary value problems in non-smooth domains.
