He was invited plenary speaker at SCAN 2002 and at SIBGRAPI 2017.
His current research interests include computational mathematics, geometric modeling, and interval methods in computer graphics, specially applications of affine arithmetic. He is also interested in programming languages and is one of the designers of the Lua language. Lua was awarded the first prize in the II Compaq Award for Research and Development in Computer Science, in 1997, and the Front Line Award 2011 from the Game Developers Magazine. Lua featured in HOPL III, the Third ACM SIGPLAN History of Programming Languages Conference, in 2007. Lua featured in the "Inovanšas – Creations Brazilian style" exhibition at the Museum of Tomorrow in Rio, in 2017.
