I am an Assistant Professor at the Department of Computer Science of the Institute of Mathematics and Statistics of the University of São Paulo. For the most part, my work has focused on the computational aspects of discrete probabilistic graphical models (e.g., Bayesian networks, credal networks, sum-product networks) and their use in classification, robust inference and planning under uncertainty. I am also interested in probabilistic programming and in probabilistic logics such as ProbLog. A possible use of probabilistic reasoning is in designing a digital student that will one day pass a university-entrance level standardized test.
