Zhenkun Li, with publish name Frank Z.K. Li, born in Hengyang, Hunan, Ph.D., and the supervisor for master’s degree.  I entered the School of Mathematics and Statistics of Wuhan University in 2010, majoring in mathematics and applied mathematics, and graduated with a bachelor's degree in science in 2014. In the same year, I entered the Center for Combinatorial Mathematics of Nankai University, followed Prof William Y.C. Chen for a doctoral degree, majoring in combinatorics. In 2019, I received my doctoral degree in science, then entered the School of Science of Chongqing University of Posts and Telecommunications. Currently, I preside over one project supported by National Natural Science Foundation of China, and one doctoral research funding of Chongqing University of Posts and Telecommunications. My research interests are the application of context-free grammars in combinatorial structures, the combinatorial proof of identities related to integer partitions, etc. I mainly undertake the teaching work of calculus, linear algebra, discrete mathematics, and mathematical modeling for undergraduates, and graph theory and its applications for postgraduates.
