In 2011 got her Master of Science (M.Sc.) degree from the Faculty of Computer Science and Engineering (FINKI) in Skopje, on the TEMPUS programme in Software Engineering. Her master thesis was in the field of Symmetric Cryptography, titled “Analysis and construction of optimal S-boxes for block ciphers with quasigroups" supervised by Danilo Gligoroski, professor at the Norwegian University of Science and Technology (NTNU) in Trondheim, Norway. From February 2012 she is a PhD student at the Faculty of Computer Science and Engineering in Skopje, under the supervision of Prof. Gligoroski. During her graduate studies she was continually awarded for her achievements.

After graduating she was employed as a teaching assistant at the Faculty of Natural Sciences and Mathematics on the Department of Informatics in Skopje. From 2011, she is working as a teaching assistant at the Faculty of Computer Science and Engineering in Skopje. Her work as a teaching assistant includes preparation and teaching of auditory and laboratory exercises for courses such as programming, algorithms and data structures, operating systems, software quality and security of computer systems security.

She is participating in a number of international and domestic scientific research projects. As a part of her scientific research activities, she has participated in numerous scientific conferences, workshops and summer schools. She is an author and co-author of many scientific research papers. Currently, her research is focused on authenticated encryption, design of lightweight ciphers and provable security in the field of symmetric cryptography.
