Research Interests and Current Research Works
ph.d. mathematics (majoring in graph theory), academy of mathematics and systems sciences, chinese academy of sciences, 2001. dissertation: some results related to cycles in graphs. advisor: professor feng tian.

My research is mainly concerned with graph structure theory. I have published more than twenty papers on this subject, five of which appear in
Journal of Combinatorial Theory Series B
Journal of Graph Theory
. I have proved three conjectures on long cycle of graphs, one of which is proposed by Enomoto et al. I also study graph algorithms and have proposed a strongly polynomial algorithm for the inverse shortest arborescence problem as well as a polynomial algorithm for the colorings of perfect circular arc graphs. Currently, my research is focused on the cycle structure, the path structure and the tree structure of graphs.
