My area of research is in algebraic graph theory and combinatorics, especially, distance regular graphs and its complete characterization with fixed parameters. I am interested in complete characterization of distance regular graphs by its Intersection number, fixed eigenvalue, fixed diameter, and valency (Regularity). Currently, I am working that when a distance-i graph has fever eigenvalues? I worked on the characterization of distance regular graphs with diameter 3, whose distance-2 graph is strongly regular. Recently, With Prof. Thomas Zaslavsky also working on strongly regular signed graphs. I am also interested in the existence and non-existence problems of a graph.
