I am presently involved in several activities of research and divulgation. 

1. I am preparing a book on the metaphysics of non-individuality with my colleague Jonas Arenhart. If you have read other entries on this page, you surely have realized that this is my core passion in research. We aim to explore the possible view that there may be absolutely indiscernible entities that are not "the same" entity, as we should conclude if we take into account classical logic (classical logic and maths do not enable indiscernible but not identical individuals). We explore several ways to deal with such entities (supposing that they can be instantiated in some way). It will be a philosophical book but grounded on logical and mathematical bases, and with physical inspirations. 

2. I am writing a book with Acacio José de Barros (State UN. of San Francisco) and Federico Holik (Un. Nacional de La Plata) about the different notions of indistinguishability in quantum physics. Our book Distinguishing Indistinguishabilities: Differences Between Classical and Quantum Regimes (it is undewr revision).

3. I am involved with the writing of a lot of Class Notes I use in my classes on logic, philosophy of science, and the foundations of mathematics. I am continuing to write and improve these notes (in Portuguese) and I intend to collect them in an introductory book for philosophers and students of mathematics and physics. The problem is not scientific, but most of the editorial houses here in Brazil cannot deal with LaTeX !

4. I am engaged with Adonai Sant'Anna (Federal University of Paraná, mathematics), with Eliza Wajch (Siedlce Un., Poland (https://www.researchgate.net/profile/Eliza-Wajch) and other people like Juan Pablo Jorge (Un. Buenos Aires), Federico Holik (Un. La Plata), Acacio J. de Barros (State Un. San Francisco) in several issues in the logic of quantum theories.

Forthcoming papers

1. "On the discrepancies between quantum logic and classical logic", forthcoming in a book honoring the logician Andréa Loparic.
