My research is focused on quantum physics, ranging from its mathematical structure, to collaborations with experimental physicists. Quantum correlations, contextuality, nonlocality, geometry of quantum states and of quantum measurements, decoherence, classical limit of quantum theory, quantum information, quantum computation, and the search for "more physical/informational" foundations for the quantum formalism are themes where I have close interest and/or produced original results.

Some of it is part of my PhD Thesis (sorry, in Portuguese). A broader perspective you can gain from my papers.
