Hi, I am Luiz Schirmer.

Assistant professor at Unisinos

email: luizschirmer [at] unisinos.br

I am a researcher and professor at Unisinos. Additionally, I was a postdoctoral researcher at the Visgraf (Vision and Computer Graphics Lab) at IMPA from 2021 to 2023. Previously, I was a postdoc researcher at the Institute of Systems and Robotics at the University of Coimbra, where I was a member of the Visual Information Security Team (VisTeam). 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.

I completed my Ph.D. at PUC-Rio, advised by Professor Hélio Lopes. Also, during my Ph.D., I worked with Professor Luiz Velho at the National Institute of Pure and Applied Mathematics (IMPA). 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.
