My areas of research are Combinatorics and Graph Theory. Research career started on studying existence and geometrisability of strongly regular graphs. Over the years I have worked on Graceful Labellings, Harmonious Labellings, Radio- Colorings, and Unit Distance Representations of Graphs. Current Research is going on the following topics:
1. Algebraic and Spectral Graph Theory
2. Irreducible No-hole Colorings
3. Self-centered Graphs
4. Existence of Strongly Regular Graphs
