My main area of work is Discrete and Computational Geometry. Currently I am a member of the editorial boards of Computational Geometry, Theory and Applications Graphs and Combinatorics Boletín de la Sociedad Matemática Mexicana. I was co-founding editor, and co-editor-in-chief (until Dec. 1999) of the journal Computational Geometry, Theory and Applications published by Elsevier. Publications: A substantial part of a book on Illumination that I am writing On-line publications.
