According to Wikipedia, Iván Gutman is a Serbian chemist and mathematician. Life and work Gutman was born in Sombor, Yugoslavia in a Bunjevac family. In 1970 he graduated chemistry from the University of Belgrade where he worked a short time as an assistant at the chemistry department. From 1971 until 1976 he worked as research assistant and senior research assistant at Ruđer Bošković Institute in Zagreb, department of physical chemistry. In 1973 he received M.Sc. degree from the University of Zagreb, in the area of theoretical organic chemistry. In the same year he received a doctorate degree in chemistry from the University of Zagreb. His supervisor was Nenad Trinajstić. From 1977 he worked at the University of Kragujevac, eventually becoming a full research professor in 1982. In 1981 he received a doctorate degree in mathematics from the University of Belgrade.
