Alexandros Lazaridis was born in 1981, in Thessaloniki, Greece. He graduated in September of 2005 from the Department of Electrical & Computer Engineering at Aristotle University of Thessaloniki. He was accepted as a PhD student at the Wire Communications Laboratory at the Department of Electrical and Computer Engineering at the University of Patras in October of 2005 and received his PhD in February of 2011. His fields of research include Speech Processing, Voice Conversion, Speech Synthesis and Speech Prosody. Until 2013 he was a post-doctoral researcher at the University of Patras and at the Aristotle University of Thessaloniki and non-tenured Lecturer at the University of Western Macedonia, at the Technological Educational Institute of Thessaloniki and at the Technological Educational Institute of Serres. Currently he is a post-doctoral researcher at the Idiap Research Institute in Martigny, Switzerland.
