Ivan Kraljevski was born in Emmen in the Netherlands in 1974. He received a B.Sc. degree in Electronics and Telecommunications in 1997, an M.Sc. degree in Computer Technology and Informatics in 2000 and a Ph.D. degree in 2004, all from the Faculty of Electrical Engineering and Information Technology at the University "St. Cyril and Methodius" in Skopje, Macedonia. From October 2011 to September 2013, he worked as a researcher in the field of speech technology at the Institute of Acoustics and Speech Communication (IAS), TU Dresden, Germany. From October 2013 to May 2019, he was employed as a research and development engineer at voiceINTERconnect GmbH in Dresden, Germany. He is currently a research associate in the project group "Cognitive Material Diagnostics" at the Fraunhofer Institute for Ceramic Technologies and Systems (IKTS). His scientific and professional interests include speech and audio signal processing, speech technology, pattern recognition and artificial neural networks.
