About

I am a mathematican, I work as an Associate professor at Guangdong Technion-Israel Institute of Technology, Shantou, China.

Interests: sandpiles; tropical geometry; analytic/elementary number theory around SL(2,Z), Farey fractions, topographs, and lattice sums; continued fractions; affine geometry.
