Jelena Djordjevic serves as a Lecturer at the Department of Mathematics and Informatics within the Faculty of Science and Mathematics at the University of Kragujevac. Her academic position places her within the institutional structure that includes the Institute of Mathematics and Informatics, one of four primary institutes comprising the faculty alongside Biology, Chemistry, and Physics. Her primary research focus lies in Differential Geometry, a specialized branch of mathematics dealing with curves, surfaces, and their properties using calculus and linear algebra. This field has significant applications in theoretical physics, particularly in general relativity and string theory, as well as in computer graphics and engineering design. Dr. Djordjevic completed her undergraduate studies in 2015 followed by her Master's degree in 2016, establishing her academic foundation in mathematics. Her work contributes to the department's research output in pure mathematics, though specific projects or collaborations are not detailed in available materials. She maintains an office at location A-II-22 within the faculty building and is listed among the academic collaborators at the institution, working under the department leadership of Professor Nenad Stojanović.
