Research
While at Stanford, Leo Guibas and Jorge worked on the then-new field of computational geometry. Among other results they developed the quad-edge data structure for two-dimensional maps, the kinetic framework for computational geometry. Jorge's Ph.D. dissertation on oriented projective geometry was later published as a book. He also drew dozens of cartoons for the DEC SRC technical reports.
In 1992 Jorge collected and widely disseminated (through the historic DEC gatekeeper ftp archives and Prime Time Freeware) a set of wordlists that later formed the basis of the ispell resources (later myspell, currently part of OpenOffice and Mozilla as hunspell).
After moving to UNICAMP, Jorge developed affine arithmetic, a model for self-validated computation (which he had conceived in 1991), in collaboration with Marcus Andrade, João Comba, and Luiz Figueiredo.
At UNICAMP Jorge also worked with C. Lucchesi and T.Kowaltowski on finite state transducer technology for spell checking and other natural language processing tasks. With his student H. Leitão he developed an efficient algorithm for pottery fragment reassembly by multiscale outline matching, and analyzed the density of useful information contained in those outlines. He has also contributed to the study of the Voynich manuscript.
Since 2001 Jorge has been involved in efforts to raise public and government awareness about the insecurity of Brazilian electronic voting machines, which are of the direct recording electronic (DRE) type and therefore vulnerable to massive and undetectable software-based vote-stealing.

Famous quotes containing the word research:
“I did my research and decided I just had to live it.”
—Karina O’Malley, U.S. sociologist and educator. As quoted in the Chronicle of Higher Education, p. A5 (September 16, 1992)
“One of the most important findings to come out of our research is that being where you want to be is good for you. We found a very strong correlation between preferring the role you are in and well-being. The homemaker who is at home because she likes that “job,” because it meets her own desires and needs, tends to feel good about her life. The woman at work who wants to be there also rates high in well-being.”
—Grace Baruch (20th century)
“Feeling that you have to be the perfect parent places a tremendous and completely unnecessary burden on you. If we’ve learned anything from the past half-century’s research on child development, it’s that children are remarkably resilient. You can make lots of mistakes and still wind up with great kids.”
—Lawrence Kutner (20th century)
