Ahmad Nasri is an associate professor at the American University of Beirut in the Dept. of Mathematics and Computer Science. He received a Ph.D. in Computer Graphics from the University of East Anglia in 1985, a B.S. degree in mathematics and a B.S. in teaching mathematics both from the Lebanese University in 1978. He has been a research engineer at MIT, a research visitor at Arizona State University and Purdue University and a research lecturer at Bremen University. He has a number of articles in TOG, CAGD, CAD, and TVC. He participated in many international conferences and workshops including SIAM Geometric Design, Shape Modeling International, Mathematics of Surfaces and SIGGRAPH. His research interests include recursive subdivision in modeling and computer graphics, free-form curves and surfaces, Data Visualization, and computer science education.

Weiyin Ma is an assistant professor in manufacturing engineering at the City University of Hong Kong. His present research interests include computer aided geometric design, CAD/CAM, rapid prototyping and reverse engineering. Before joining CityU in 1995, he worked as a research fellow in Materialise N.V., a rapid prototyping firm in Belgium, and the Department of Mechanical Engineering of the Katholieke Universiteit Leuven (K.U.Leuven), Belgium. He obtained a B.Sc. in 1982, an M.S. in 1985 from the then Nanjing University of Science and Technology, Nanjing, China, an M.Eng. in 1989 and a Ph.D. in 1994 from K.U.Leuven.
