I recently organised a GIAN program (brochure) on the relation between the theorey of Minors and that of Homomorphisms of graphs. The main speaker is Reza Naserasr, IRIF, France.

An article on an upcoming organic farming technique. It is only being written and is incomplete as of now. I hope to finalise it in a couple of manths. You can access the first draft version Here

Seminar:

I organise a weekly seminar on topics related to graph theory, combinatorics and discrete mathematics in general.

Research Interests

Combinatorics: Structural graph theory, Colouring and decompositions, Axiomatic characterization, Graph Ideals.
