I am a Principal Research Scientist with Yahoo! Research, and an Adjunct Associate Professor of Computer Science at the University of California, Berkeley where I am also part of the UC-Berkeley Database Group.

My current research interests lie in the areas of probabilistic data management, approximate query processing, data streaming, network management, data mining, and XML and text databases.

I am originally from the beautiful city of Chania on the island of Crete, Greece. (I guess that explains my first name.) I received my BSc (Valedictorian, School of Engineering) in 1992 from the University of Patras, Computer Engineering and Informatics Dept. (UOPCEID). I also spent the following year at UOPCEID as a post-graduate fellow. In the Fall of 1993, I joined the graduate program in Computer Sciences at the University of Wisconsin - Madison, where I received my MSc (1994) and PhD (1998) under the supervision of Prof. Yannis Ioannidis. I joined the Database Principles Research Department at Bell Labs as a Member of Technical Staff in September 1998. In July 2005, I took a Senior Research Scientist position at Intel Research Berkeley. I moved to Raghu Ramakrishnan's Community Systems group at Yahoo! Research in late February 2007.

My personal homepage at UC Berkeley contains more information, including online publications and talks.
