Mursaleen has been a reviewer for various international scientific journals and is a member of numerous editorial boards for various international scientific journals. He has received a number of awards for his research achievements and was recognized as a 2019 Highly Cited Researcher by the Web of Science.

Dragan Djordjevic received his degrees in mathematics from the University of NiS Serbia: Bachelors in 1992, Masters in 1996, and a PhD in 1998. He has worked at the University of NiS since 1992, and from 2006, as full Professor at the Faculty of Sciences and Mathematics. He has taught courses in various levels of education (Functional Analysis, Operator Theory, Complex Analysis, Measure and integration, Algebras of Operators) and served as the Dean of the Faculty of Sciences and Mathematics, a member of several scientific boards of the University of NiS (Senat, Scientific Council for Sciences and Mathematics), Ministry of Education, Science and Technological Development of Serbia (Scientific Council for Mathematics, Mechanics and Computer Science, Head of the council), as well as in the Republic of Serbia (National council for higher education). He was the head and member of several scientific projects financed by the Ministry of Education, Science and Technological Development of Serbia. He is a member and vice president of the Association Serbian Scientific Mathematical Society. Djordjevic supervised 10 PhD theses (8 in NiS, 1 in Belgrade and 1 in Skopje). He has published 130 scientific papers, including 104 papers in JCR journals. He has collaborated with more than 30 authors, most of them his students, and his results are cited approximately 1400 times, with a Hirsch index of h=22.

Djordjevic has been as an invited speaker for mathematical conferences in Korea, Japan, and Turkey, has organized conferences in mathematical or functional analysis in NiS and Novi Sad, has reviewed papers for mathematical journals, including Mathematical Reviews. His cientific work includes operator theory, with some aspects of functional analysis, linear algebra, general algebra and numerical analysis. His main focus is on operators on Banach and Hilbert spaces, their ordinary and generalized invertibility properties, Fredholm and spectral theory, as well as applications to general ring theory, and operator equations in various structures. He has results related to majorizaion and doubly stochastic operators, theory of spaces with indefinite inner products, and Hilbert C*- modules. Dragan Djordjevic sits on the boards of these mathematical journals: Filomat (one of the editors-in-chief), Functional Analysis, Approximation and Computation (founder, editor-in-chief), Applied Mathematics and Computer Science (founder, one of the editors-in-chief), Advances in the Theory of Nonlinear Analysis and its Application (member of the board), Publications de l'Institute Mathematique (member of the board), and Advances in Operator Theory (member of the board).
