Research Interests and Current Research Works
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 Band   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.
