I am an Associate Professor in the Department of Computer Science of Durham University. I have a degree in mathematics from the University of Thessaloniki, Greece and a PhD in mathematics from the University of Southampton. Before joining Durham University I was a lecturer at the Department of Creative Computing in Coventry University. Before that, I was a researcher at the Department of Computer Graphics of the
Max-Planck Institut fuer Informatik, in Saarbruecken, Germany and before that, a Research Associate at the Computer Laboratory of Cambridge University.

My research interests are in the area of computer graphics. In particular, I work on subdivision surfaces, polygonal mesh encoding and the application of statistical learning methods in surface reconstruction from scan data.

• 2003: Talk at Computer Science Colloquia, University of Wales Swansea, UK: I was invited to give a talk at Computer Science Colloquia, University of Wales Swansea, UK. The title was "Statistical Learning in Surface Reconstruction".
• 2002: Talk at Workshop on Geometric Modeling, Dagstuhl, Germany (Dagstuhl event 02201): I was invited to participate and give a tak at the Workshop on Geometric Modeling, in Dagstuhl, Germany, in May 2002. The title of the talk was "Evolving n-gons in subdivision schemes with small support".
