Full Name          Harilaos Koumaras

Position              Computer Science Researcher

Nationality          Greek

Dr. Harilaos Koumaras was born in Athens, Greece in 1980. He received his BSc degree in Physics in 2002 from the University of Athens, Physics Department, his MSc in Electronic Automation and Information Systems in 2004, being scholar of the non-profit organization Alexander S Onassis, from the University of Athens, Computer Science Department and his PhD in 2007 at Computer Science from the University of Athens, Computer Science Department, having granted the four-year scholarship of National Centre of Scientific Research "Demokritos". He has received twice the Greek State Foundations (IKY) scholarship during the academic years 2000-01 and 2003-04. He has also granted with honors the classical piano and harmony degrees from the classical music department of Attiko Conservatory. In 2003 he joined the Media Networks Lab at the National Centre of Scientific Research “Demokritos” and participated in numerous EC-funded and national funded projects with presentations and publications at international conferences, scientific journals and book chapters. His research interests include objective/subjective evaluation of the perceived quality of multimedia services, video quality and picture quality evaluation, video traffic modeling, digital terrestrial television and video compression techniques. Currently, he is the author or co-author of more than 75 scientific papers in international journals, technical books and book chapters, numbering more than 250 non-self citations (according to ResearchGate). He is an editorial board member of the Telecommunications Systems Journal and a reviewer of the IEEE Network magazine, the EURASIP Journal of Applied Signal Processing, the IEEE Transactions on image processing and the IEEE Transactions on Broadcasting. Dr. Koumaras is a member of IEEE, SPIE and National Geographic Society.
