I'm doing a second Ph.D., in the philosophy of science and technology, at the University of São Paulo. I'm a member of the (professional philosophy) Association for Scientiae Studia, and the Association for the Philosophy and History of Science of the Southern Cone. My computer science research is currently concerned with uncertainty management in expert systems and Artificial Intelligence. Please find my computer science publications at DBLP. (For Brazilians, here's my CNPq Lattes:

At IBM Research in Brazil, I work under the leadership of Dr. Rogerio de Paula on the design and application of AI techniques to serve the natural resources industries. In my one-year postdoc at the University of Michigan (last time I checked, top-5th CS department in the world) I've worked with (h-index 88) Prof. H. V. Jagadish and have developed a (statistical inference) Bayesian smoothing algorithm for the disambiguation of search and natural language queries issued against a relational database (by building on information available from the database schema and a user-interaction log). In my Ph.D. work at the National Laboratory for Scientific Computing (LNCC) in Brazil, I've developed a technique named Y-DB to extract causal graphical models (with correctness guarantees) from competing sets of mathematical equations (seen as alternative hypotheses, and given in MathML), and then generate automatically a compact probabilistic relational database (so-called U-relations). As part of that research, I have fixed the status of a classical AI algorithm for causal reasoning proposed in the 1950's by Nobel-laureate Herbert A. Simon. 

I earned my Ph.D. in Computational Modeling (computer science, applied math and physics) in January 2015 from the National Laboratory for Scientific Computing (LNCC) in Brazil. My Ph.D. dissertation has been nominated to the 2016 nation-wide edition of 'Prêmio CAPES de Teses'. During the Ph.D. I've been awarded an IBM PhD Fellowship (2013-14), and a FAPERJ Straight 'A' Scholarship (2013-15). I also hold a M.Sc. and a B.Sc. in Computer Science from the Federal University of Espirito Santo (UFES) in Brazil.
