My main areas of research are in graph theory and combinatorics.
I am particularly interested in graph coloring, extremal problems
involving chromatic numbers and planar graphs. I have also done some
work in hypergraphs and partially ordered sets.
Some of my recent papers:
1. On a construction of graphs with high chromatic capacity and large girth, in Discrete Mathemaitcs.
2. A lower bound for the chromatic capacity in terms of the
chromatic number of a graph, in Discrete Mathematics.
3. On graph orientation and the number of vertices in a longest directed path, submitted.
4. On color critical graphs with large adaptable chromatic numbers, submitted.
