I studied Mathematics and computer science at the Aristoteleion University of Thessaloniki (Greece) where I graduated in 1988. Sponsored by a Fulbright Scholarship, in 1990 I received my Masters degree in Mathematical Logic from Indiana University in Bloomington, Indiana (USA). I became interested in Topology with particular emphasis in Four Dimensional Manifold Theory and obtained my Ph.D. in 1994 for my thesis “On 2-spheres in 4-manifolds”.

In 1994 I became a Leibniz Fellow at the Max-Planck-Institut for Mathematics in Bonn (Germany). From 1997 to 1998 I shifted my research focus to Classical Knot Theory and Computer Science. I also worked on commercial web design projects for various Bonn-based businesses. In 1999 I was Visiting Fellow at the Aristoteleion University of Thessaloniki. I am a member of the DDI alliance Experts Committee, advisor at the Open Data Foundation and a member of the Scientific Advisory Board of DSZ-BO, the Data Service Center of the Faculty of Sociology at the University of Bielefeld.

I have published papers in mathematical journals such as Manuscripta Mathematica, Mathematische Zeitschrift, Knot Theory and Its Ramifications, The Kobe Journal of Japan, Topology and Its Applications. I am also the author of several stata modules. My interests include Remote Access/Computing/Processing, Data management, Systems Design, Internet Econometrics, Psychology, Theoretical Biology and Game Theory.

I am the Head of the IZA International Data Service Center and IZA CTO. My IZA business page has a copy of my CV.
