He is a leading expert on the geometric representation of graphs, including his recent work on representation of cubic graphs as the contact graph of axis-parallel rectangles. His investigations of various aspects of the notion of boxicity of graphs have led to the development of important upper and lower bounding techniques. His works address and make progress on deep open problems in graphs theory, including the famous Hadwiger’s conjecture.
