I am currently a PhD student at COPPE/UFRJ, working at LCG - Computer Graphics Laboratory. Recently I was research assistant at IMPA, working with professor Luiz Velho at Visgraf laboratory. I have been working with geometric modeling of curves and surfaces, sketch based modeling, computational manifolds, fluid simulation and GPU programming (OpenGL Shading Language and CUDA).
