I graduated in 1978 from the Lebanese University with a B.S. in Pure Mathematics from the Faculty of Sciences and a B.S. in Teaching Mathematics from the Faculty of Education. I then joined Essex University for an M.Sc. in Computer science and after completing the qualifying year I moved to the University of East Anglia to continue a Ph.D. in computer graphics under the supervision of Professor A. R. Forrest. My research interests include:   Recursive Subdivision in Computer Graphics   Computer Aided Geometric Design including       Free-form curve and surface representation   Recursive Subdivision Surfaces over Arbitrary Topology    Solid Modeling   Interpolation Conditions in Recursive Subdivision: Points, Normals, and Curve interpolation   Computer Science Education and Mutlimedia
