Biography

Irena Oršolić is a Postdoctoral researcher at the University of Zagreb, Faculty of Electrical Engineering and Computing, and a member of the Multimedia Quality of Experience Research Lab (MUEXlab). She received her B.Sc. degree in Computing in 2014, M.Sc. degree in Information and Communication Technologies in 2016, and her Ph.D. degree in the field of Computing in 2020 at the same faculty. The focus of her research is on potential solutions for QoE monitoring of multimedia services that could possibly enable the development of mechanisms for improving QoE and efficient use of network resources.
