Campinas, Brazil

I’m a third-year Ph.D. candidate in Computer Science at the Institute of Computing at the University of Campinas (IC - UNICAMP). I’m a member of the Hub of Artificial Intelligence and Cognitive Architectures (HIAAC), performing research in Trusthyworth AI, mainly in the area of fairness and explainability. I hold a MSc in Mathematical Modelling at the School of Applied at FGV and BSc degree in Applied Math from the same institution. In the last few years, I have been a researcher at the Visual Data Science Lab(VDS), working on visualization techniques for spatiotemporal data. I also had the opportunity to be a visiting researcher in the VIDA Lab at NYU Tandon, working with deep learning techniques to predict socioeconomic indexes from remote sensing data.
