Currently, I'm a third-year undergraduate in group theory in Southern University of Science and Technology of China.
I'm also a TA of Linear Algebra at present, using Linear Algebra Done Right as text book, which is my favorite book of linear algebra.
Now I'm studying permutation groups (O'Nan-Scott theorem in particular), algebraic graph theory (group theoretic view, the cover of an arc-transitive graph in particular), and basic classical groups.
