Now, I'm a **Postdoctoral Fellow** at the University of Nevada, Reno, working with
Chris Rogers.

**Ph.D.** Mathematics, Northeastern University, Boston, 2016.
(Advisor: Alexandru I. Suciu).
I also had many very nice discussions with
Kiyoshi Igusa.

**M.S.** Mathematics, Nankai University, Tianjin, 2010.
(Advisors: Liu, Xiugui,
and Wang, Xiangjun).

**B.S.** Mathematics and applied mathematics, Hebei Normal University, 2007.

Here is my ** CV **. I am in
MathSciNet,
Google Scholar,
arXiv,
ResearchGate.

My research interests are in **Algebraic Topology** and **Group Theory**, and their relation with Algebra, Geometry
and Combinatorics. More specifically,

1. Rational homotopy theory, especially formality properties and Massey products.

2. Cohomology jumping loci: characteristic varieties and resonance varieties of spaces and CDGA models.

3. Combinatorial group theory, especially various Lie algebras associated to finitely generated groups.

4. Configuration spaces, pure virtual braid groups, pure welded braid groups, fundamental groups of algebraic varieties, picture groups from the quiver representations, etc.

When I worked on my MS degree, I did some computations (see **Papers** )
on the stable homotopy theory of spheres using the May spectral sequence.

Recently, I am working on problems relating the $A_{\infty}$-structures on group cohomology.
