Discrete math, mostly in graph theory; I am currently working on
the structure of graphs with certain

In particular I am interested
in the Erdos-Hajnal conjecture and
in the various conjectures of Gyarfas about
chi-boundedness.
The web pages of Maria Chudnovsky and
Robin Thomas have more information
about our joint work.
Here are websites for the last ten Barbados graph theory workshops and the current one:
