I am a Computer Science PhD researcher at the University of São Paulo (USP) specializing in 3D/4D reconstruction from images, computer vision, and geometric modeling. My current work focuses on 3D Gaussian Splatting (3DGS) and geometrically consistent surface extraction.

I hold a Bachelor’s degree in Pure Mathematics from the State University of Londrina (UEL). While there, I managed over 40 distinct projects within the Mathematics Tutorial Education Program (PET) and spent over two years as a data science researcher to optimize Covid-19 spread predictions. This background heavily inspires my approach to computer vision, a transition I solidified during my Master’s degree focusing on human skin tone classification, as well as through industry experience as a Computer Vision Engineer at Wikki/Wiise Brazil applying state-of-the-art models to microfossil segmentation.

In a complete theory there is an element corresponding to each element of reality. A sufficient condition for the reality of a physical quantity is the possibility of predicting it with certainty, without disturbing the system. In quantum mechanics in the case of two physical quantities described by non-commuting operators, the knowledge of one precludes the knowledge of the other. Then either (1) the description of reality given by the wave function in quantum mechanics is not complete or (2) these two quantities cannot have simultaneous reality. Consideration of the problem of making predictions concerning a system on the basis of measurements made on another system that had previously interacted with it leads to the result that if (1) is false then (2) is also false. One is thus led to conclude that the description of reality as given by a wave function is not complete.
