Yannis Ioannidis is currently a Professor at the Department of Informatics and Telecommunications of the University of Athens.

He received his Diploma in Electrical Engineering from the National Technical University of Athens in 1982, his MSc in Applied Mathematics from Harvard University, and his Ph.D. degree in Computer Science from the University of California at Berkeley in 1986. Immediately after that he joined the faculty of the Computer Sciences Department of the University of Wisconsin at Madison, where he became a Professor before finally leaving in 1999. His research interests include database and information systems, digital libraries, personalization, scientific systems and workflows, eHealth systems, and human-computer interaction, topics on which he has published over seventy articles in leading journals andconferences. He also holds three patents.

Yannis is an ACM Fellow (2004) and an IEEE Fellow (2010). He is also a recipient of the VLDB "10-Year Best Paper Award" (2003), the "Presidential Young Investigator Award" - PYI (1991), and of several awards for teaching excellence, including the nation-wide "Xanthopoulos-Pneumatikos Award for Outstanding Academic Teaching" in Greece(2006) and the "Chancellor's Award for Excellence in Teaching" at the University of Wisconsin (1996). He has also been a keynote or invited speaker in several conferences (NLDB'08, ICDE'07, ADBIS'06,CIKM'05, ICDT'03, WAIM'01, SSDBM'00, PDP'00, ECDL'98).

Yannis has been a (co-)principal investigator in over thirty research projects funded by various government agencies (USA, Europe, Greece) or private industry. He is currently an Associate Editor of several journals (Information Systems, Journal of Digital Libraries, Journal of Intelligent Information Systems, and Journal of Digital Curation) and has been a member of the program committees of over sixty conferences, six times as (co-)chair (ICDE'09, ADBIS'07, EDBT'06, HDMS'03, VLDB'02, VDB'98, and SSDBM'97).

Yannis currently serves a 4-year term as the ACM Sigmod Chair (he was Vice-Chair during July 2005-June 2009) and is a member of the Scientific Advisory Board of the Max Planck Institute for Informatics. He has also served on the review board of the Lawrence Berkeley Laboratories in Berkeley and on the Science Council of the (now defunct) CESDIS Center for Excellence in Space Data and Information Sciences.

Finally, between July 2002 and March 2004 he served as the Information Technology advisor to the Minister of Health of Greece.
