About me:
Currently I am an assistant professor at SUStech, Department of Mathematics.
I received my Ph.D. in Mathematics from U Houston under the supervision of Prof. Andrew Török.
I was a Hale visiting assistant professor at Georgia Tech, School of Mathematics, working under Prof. Leonid Bunimovich,
and was a research fellow of Prof. Carlangelo Liverani at Rome Tor Vergata, Department of Mathematics.
My research area is analysis.
More precisely, open dynamical systems, hyperbolic dynamical systems, ergodic theory, probabilistic limit theorems of dynamical systems, and their applications to physics. Here is my Research Statement

Teaching:
Currently I have zero teaching duty.
In the past, I taught various courses including calculus, linear algebra, probability, statistics, differential equations and combinatorics.
