I am a researcher at the Institute of Systems and Robotics at the University of Coimbra, where I am a member of the Visual Information Security Team (VisTeam). Also, I am a postdoctoral researcher at the Visgraf (Vision and Computer Graphics Lab) at IMPA. My research primarily relates to multilinear (tensor) algebra and Deep Learning for Computer Vision. I'm also very interested in Image Processing, Computer Graphics, and Machine Learning in general.


I completed my Ph.D. at PUC-Rio, advised by Professor Hélio Lopes. Also, during my Ph.D., I spent time at the National Institute of Pure and Applied Mathematics (IMPA) working with Professor Luiz Velho. Before starting my Ph.D., I obtained a Master's degree in Informatics from PUC-Rio and a Bachelor's in Computer Science from UFSM, where I worked with Professor Cesar Pozzer. Also, in the past, I worked with Professor Waldemar Celes at Tecgraf Institute on the project Geresim: Reservoir Simulation Management.
