About

I am an Assistant 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, but I am generally interested in image and signal processing, computer graphics, and applied mathematics.

I earned my Ph.D. in Computer Science from UFRGS under the supervision of Dr. Manuel M. Oliveira. Our work 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.
