Thiago Pereira 's Research

Master student in Mathematics (major Computer Graphics) at IMPA

About me

I am a computer graphics Master student at Instituto Nacional de Matemática Pura e Aplicada in Rio de Janeiro and a member of the Vision and Graphics Laboratory. My advisor is Luiz Velho. My research interests include image based modelling and rendering techniques and methods for shape analysis and representation.

I hold a BEng in Computer Engineering at Instituto Militar de Engenharia where I now coach teams for the ACM-ICPC programming competition. I was also an intern at Chemtech - A Siemens Company and Morning Star Consulting. My cv is here.
