Combinatorics, in particular extremal graph, extremal hypergraph theory and enumerative combinatorics.

The broad field of Khare's research is combinatorics, in particular extremal set theory, graph theory, hypergraph theory and enumerative combinatorics. Application of graph theory and hypergraph theory in developing algorithms based on new research involving constructional proofs over existential ones also interests Khare, as well as application of combinatorics to business, biology and physics. His work can be partitioned into two areas: work on graphs and hypergraphs, and work on enumerative combinatorics.

Graphs, hyper-graphs, parking functions, matchings, degree, independent set, enumeration, moments.
