About

I am an Adjunct Professor at the Institute of Informatics of the Federal University of Rio Grande do Sul (UFRGS), in Brazil . My work focuses on efficient and novel filters for images and videos, and I am generally interested in space-frequency analysis, sampling theory, image and signal processing, computer graphics, and applied mathematics. I am actively looking for students interested in these areas who wish to pursue a master's degree or undergraduate studies. If you would like to work with me please check my research below and contact me by e-mail.

I hold a Ph.D. in Computer Science from UFRGS where I worked with Dr. Manuel M. Oliveira. Our research on efficient high-dimensional filtering for image and video processing was awarded the ACM SIGGRAPH Outstanding Doctoral Dissertation Award and first place in the Brazilian Computer Society's Doctoral Dissertation Contest.

You can find me at Office 219 Building 43424 - Campus do Vale. Full address: Instituto de Informática, Universidade Federal do Rio Grande do Sul, Av. Bento Gonçalves 9500, 91501-970 Porto Alegre - RS - Brasil (Caixa postal 15064).
