For Prospective PhD students:

I work broadly on two things: Algebraic Graph Theory and Domination in Graphs.

In AGT, I am interested in and working on vertex-transitive graphs and many open questions related to it e.g., Polycirculant Conjecture, Lovasz's Conjecture and their variants. In graph domination, I mainly focus on different variants of domination and relations between them.

As a prospective student, I expect the following from you:

1. You should enjoy counting. While working with me, I expect research to be your primary intellectual occupation.

2. As prerequisite, you should have a good knowledge of linear algbera and group theory (any standard post-graduate course). Though, it is not absolutely necessary to have done a course on Graph Theory, but a preliminary idea about it would be appreciated. "Introduction to Graph Theory" by D.B. West is a goodbook to start with.

3. If you are interested in AGT, you should read Chapters 1-6 of the book "Algebraic Graph Theory" by Chris Godsil and Gordon Royle, before contacting me. Similarly, for graph domination, the must-read is Chapters 1-10 of the book "Fundamentals of Domination in Graphs" by T. Haynes, S.T. Hedetniemi and P. Slater.

Others: As a general policy, I do not offer reading courses or student internships.
