About Myself
I am an assistant professor in
Department of
Mathematics
in the
School of Computing and Mathematics
at
Georgia Southwestern
State University. I
received my Ph. D. in Mathematics from
Department of
Mathematics
,
The Ohio State University
under the supervision of
Dr. Michael Davis
.

Publications and Talks
Here is a list of my publications, some conference
and seminar talks. My recent work on Coxeter groups is included
in
A note on parabolic subgroups
of a Coxeter group;
On irreducible, infinite, nonaffine Coxeter groups;
A note on irreducible, infinite Coxeter groups.
The following is a link to one of my joint work on the numerical study of
some bifurcation diagrams of quadratic differential systems.
Some bifurcation diagrams for limit cycles of quadratic differential systems.
About my research and teaching
My research
interests include geometric group theory
(specifically,
Coxeter groups and metric spaces of non-positive curvature) and
dynamical systems (specifically, bifurcations of vector fields).
At Georgia Southwestern, I am teaching college algebra, precalculus, calculus, elementary
statistics, discrete systems and scientific computation.
At Ohio State, I taught several calculus sequences, some
precalculus courses and
a discrete math course.
I taught introductory courses
of complex analysis and differential equations to engineering students
at Peking University in China.
