I am a Privatdozent (Priv.-Doz.) and habilitated researcher at the Department of Information Technology, Alpen-Adria-Universität (AAU), Klagenfurt, Austria, where I focus on end-to-end aspects of video streaming within the ATHENA project. I received my Ph.D. in Computer Engineering from Ferdowsi University of Mashhad, Iran. My research focuses on the design, analysis, and optimization of complex networked systems, particularly for applications like adaptive video streaming and real-time multimedia delivery.
