Dragan Marušič

Slovenian mathematician

Dragan Marušič, born in 1953 in Koper, serves as a central figure in the development of the Slovenian school of research in algebraic graph theory. His academic trajectory, spanning institutions from the University of Ljubljana to the University of Primorska, focuses on the structural symmetry of graphs and the intricate actions of finite groups on combinatorial objects.

Academic Formation and International Experience

Marušič attended gymnasium in Koper from 1968 until 1972. He pursued his undergraduate studies at the University of Ljubljana, completing his degree in technical mathematics in 1976. He later traveled to England, earning his PhD from the University of Reading in 1981 under the supervision of Crispin Nash-Williams. Following a post-doctoral fellowship at the same institution in 1983, he returned to Koper to teach high school mathematics. His early international career included a tenure at the University of Minnesota Duluth and three years spent at the University of California, Santa Cruz, between 1985 and 1988.

Contributions to Algebraic Graph Theory

His research portfolio comprises over 100 publications centered on permutation group actions. His work addresses the existence of semiregular automorphisms of vertex-transitive graphs and investigates Hamiltonian paths and cycles. Significant research output includes classifying 2-arc-transitive circulants and studying half-transitive graphs. In collaboration with other researchers, he established that the Gray graph, which contains 54 vertices, is the smallest cubic semi-symmetric graph. He is also a founding editor-in-chief of the journal Ars Mathematica Contemporanea alongside Tomaž Pisanski.

Institutional Leadership in Slovenia

Upon returning to Slovenia in 1988, Marušič joined the faculty at the University of Ljubljana, achieving the rank of full professor in 1994 and serving as vice-rector of student affairs from 1989 to 1991. He was instrumental in the establishment of the University of Primorska, where he launched the Faculty of Mathematics, Natural Sciences, and Information Technologies. He served as dean of this faculty from 2007 to 2011. Subsequently, he held the position of rector of the University of Primorska from 2011 until 2019.

Awards and Professional Recognition

In 2002, the Slovenian government honored Marušič with the Zois Award, the nation's highest scientific distinction, in recognition of his advancements in graph theory and algebra. Since 2010, he has contributed to the national scientific evaluation process as a member of the committee responsible for selecting Zois Award recipients. Throughout his career, he has supervised seven PhD students and multiple post-doctoral fellows at his home institutions.
