Early on my scientific carer, I became deeply interested in the conceptual issues raised by quantum mechanics and its possible relationship to physical reality and metaphysics (or, more specifically, ontology). For that reason, I have always worked extensively on foundational issues in physics, and, more recently, I have been devoting an increasingly larger amount of my time to the physics of the brain and theories of learning. Thus, my interdisciplinary interests integrate the foundations of physics, biophysics, and philosophy. Below, you will find a summary of my main research areas. Most of my papers can be found in the Publications section of my website.

1.
Foundations of quantum mechanics. My main long-term focus is on realistic interpretations of quantum mechanics and its implications for causality and the structure of spacetime. I am also interested in the principles that may define quantum mechanics, particularly in the role that a quantum ontology of non-individuals plays in them.
2.
Mind and Brain. Since the early days of quantum theory, many physicists toyed with the idea that there is a connection between consciousness and quantum physics. Related to that, I am interested in modeling brain functions, particularly learning, from underlying physically plausible assumptions and macroscopic phenomena. I am also interested in how quantum physics meets consciousness, if at all.
3.
Science education. I am researching the fragmentation of epistemological views of physics students and pre-service physics teachers, how it relates to reasoning skills and instruction, and their understanding of how knowledge is constructed in science.
4. Foundations of Mathematics. My math research is related to my foundations of quantum mechanics. In particular, I am interested in how negative probabilities can describe contextuality and whether quasi-set theory can create contextual situations where negative probabilities can naturally arise.
