SHORT BIOGRAPHY

Dragan Djurčić was born on September 13 1967 in Kraljevo. He now lives in Vraneši near municiplaity Vrnjačka Banja. He is married and has two children.

He graduated at the Faculty of Mathematics, University of Belgrade in 1992, and defended his Magister of Science thesis at the same faculty in 1995.

He defended his Ph.D. thesis entitled "Karamata's Theory and Theorems of Tauber Type" in 1999 at the Faculty of Science, University of Kragujevac.

He is author and co-author of more than 30 papers published in top international scientific journals. He also presented his research results at many important mathematical conferences devoted to mathematical analysis that were held in Serbia in the last 10 years.

Besides analysis, other areas of his research interest are Selection principles, Topological Games and Fuzzy Theory.

He is the author and co-author of 6 university books (3 textbooks and 3 books of solved problems for students). He is also co-author of three chapters in an international monograph.

He was teaching at the Faculty of Mathematics, University of Belgrade, Faculty of science, University of Kragujevac, Faculty of Mechanical Engineering in Kraljevo, University of Kragujevac, Faculty of Philosophy, University of East Sarajevo (Bosina and Herzegovina), College of Technical Engineering in Čačak.

In the last 10 years he takes part in projects funded by Ministry of Science of Republic Serbia (A1 cathegory). He is member of Editorial boards of 2 widely recognized international jourals.
