of research include algebraic, structural and topological graph theory, and
theory of computing. He received his PhD from the University of Ljubljana
in 1986 under Tomaž Pisanski.

Mohar’s research studies the interconnections between graphs, topology,
geometry, and algebra, as well as graph minors, colorings and nowhere-
zero flows. His work in graph theory is extended with developments of
algorithmic and computational tools in these areas.

He co-authored Graphs on Surfaces (2001) with Carsten Thomassen, an
influential book on topological graph theory, and proved a remarkable
theorem that the question whether a given graph embeds in a given
closed surface can be answered in linear time. His work in spectral graph
theory builds a bridge between graph theory and some other branches of
mathematics such as theoretical computer science and operator theory.

In 2010, Mohar received the Institute of Combinatorics and its Applications
(ICA) Euler medal for contributions to combinatorial research. The citation
reads: “Bojan Mohar’s outstanding research and leadership over a period of
thirty years place him as one of today’s foremost discrete mathematicians
worldwide. His deep and important contributions have dramatically
improved our understanding of the structural properties of graphs.” In
2018 he received the Royal Society of Canada John L. Synge award for
outstanding research and a SIAM fellowship for his “contributions to graph
theory and algorithms, in particular structural, topological, and algebraic
graph theory.” The Republic of Slovenia has also recognized Professor
Mohar with two awards for scientific excellence: the Boris Kidrič prize
(1990), and, for his work in Canada, Ambassador of Science of the Republic
of Slovenia (2009).

Professor Mohar holds a Tier 1 Canada Research Chair in Graph Theory at
Simon Fraser University, Canada, and is also a professor of Mathematics
at the University of Ljubljana, Slovenia, and a member of the Institute of
Mathematics, Physics, and Mechanics, Ljubljana.
