My main research area is Graph Theory.

At present, I am interested in      Signed Graph, Graph Homomorphism

                                                                 Quantum Walk on Graphs

                                                                 Perfect State Transfer

                                                                 Graph Labeling

                                                                 Distinguishing Labeling
