Prof. Radko Mesiar,DSc., born August 26, 1951 in Bratislava , graduated 1974 at Comenius University Bratislava in Mathematics. He obtained his PhD. from the same university in 1979 and in 1983 he became the associate professor at the Slovak Technical University Bratislava. Since 1995, he became the leading researcher at the Slovak Academy of Sciences, Institute of Mathematics , Bratislava and at the Czech Academy of Sciences , Institute of information theory and automation, Prague. In 1996, he defended the thesis " Triangular norms : theory and applications" and received the DSc. title (the highest scientific degree in Slovakia and Czech Republic). Since 1998 he became a full professor at Slovak University of Technology , Bratislava.

Prof. Mesiar is the vice-head of the Department of Mathematics of the Faculty of Civil Engineering , Slovak University of Technology Bratislava, since February 1, 2000. In the same time, he is a leading researcher at the Institute of Information and Automation of the Czech Academy of Sciences in Prague (since July 1, 1995). From February 1, 1994, till January 31, 2000, he was the head of the Dept. Mathematics. From June 20, 1983, till January 31, 1994, he gave lectures in mathematics, probability and statistics at the Slovak Technical University Bratislava as an associated professor, being a vice-head of the Dept. of Mathematics in 1987-1989 and in 1991-1994. From 1979 till 1983 he served as an assistant professor at the Dept. of Mathematics of FCE STU Bratislava.

Prof. Mesiar is author of more then hundred eighty scientific papers in mathematics. He presented his results at more then 70 international conferences. His main fields of interest are the fuzzy sets, fuzzy logic, non-additive measures and integrals, triangular norms, aggregation operators, ergodic theory and entropy. He has cooperated with several distinguished experts in the field, e.g. prof. Klement (JKU Linz), prof. Pap ( Uni Novi Sad), prof. Mareš (Czech Academy of Sciences), dr. Navara (CTU Prague), prof. Kerre and prof. De Baets (Uni Gent), prof. Benvenuti (University “La Sapienza”, Roma), prof. Thiele (Uni Dortmund), prof. Calvo (Uni of Alcala, Spain) and prof. Bouchon-Meunier (Uni Paris VI), having joint scientific papers with all mentioned scientists. He is the referee of 12 international journals, e.g. Fuzzy Sets and Systems , Information Science, Rend. di Matematica (Roma), Mathware and Soft Computing, IEEE Fuzzy Systems, IEEE Man, Machine and Cybernetics, Kybernetika, Uncertainty, Fuzziness and Knowledge-Based Systems, etc. Since February 1998, he is an associated editor of international journal Fuzzy Sets and Systems responsible for the area of non-additive measures, possibility measures and fuzzy numbers. Since 2002, he is a member of editional board of international journal Kybernetika. Moreover, he is member of editional boards of international journals Tatra Mount. Math. Publ. (Bratislava) and J. Appl. Math. (Novi Sad).

Prof. Mesiar is the coordinator of the international project CEEPUS Sk-42 “Fuzzy Control” ( STU Bratislava, JKU Linz, TU Budapest, CTU Prague, Uni Ostrava, TU Cracow, SIU Gyor ) and the national coordinator of the EC project COST 274 “TARSKI”. He is the member of the board of newly created international fuzzy association EUSFLAT. Since 1996 till 1999, he was the national coordinator of the EC project COST 15 “Many – valued logics for computer science applications”. He was the member of international program committees of more than 50 international conferences. He was the program committee chair of the congress IFSA'97 in Prague. With his PhD. students and his research group, he is (or has been) the organizer of several international meetings, e.g. international conferences FSTA (1992, 1994, 1996, 1998, 2000, 2002), 1st Fuzzy Workshop of Czechia and Slovakia 1995, Summer School on Fuzzy Control 1996, Summer School on Advanced Control 1997, Intelligent Computing '2000, Uncertainty Modelling 2001.

Prof. Mesiar has been a visiting professor at several universities in Germany, France, Italy, Austria, Spain, etc. In the last period, he gave courses for PhD students on non-additive measures and integrals ( University “La Sapienza”, Roma, May 2000), on aggregation operators ( University Alcala, March 2001) and on decision making and many-valued logics ( JKU Linz, October 2002 - January 2003).
