Leonardo P. G. De Assis
Mathematics Instructor (ULO)
Leonardo P. G. De Assis is a theoretical physicist. He currently holds a lecturer position at the School of Humanities and Liberal Studies, San Francisco State University, and as an instructor at Stanford Pre-Collegiate University Level.
He joined Stanford in 2013 and has since served in various roles. He was a Lecturer at the Department of Philosophy (2018), a Research Associate (2015-2018), a Visiting Scholar (2013-2015) at the Center for the Study of Language and Information (CSLI), a Lecturer at Symbolic Systems Program since 2018, and instructor at Stanford Continuing Studies.
He received his Bachelor's degree in mathematics from the Federal University of Rio de Janeiro, Brazil, and he has Master's and Ph.D. degrees in Physics from the Brazilian Center for Research in Physics, Brazil, with publications in nonlinear dynamics, quantum field theory, nuclear physics, atomic physics, cosmology, physics of plasmas and quantum-like formalism applied to cognition.
He is also interested in Quantum Computing, Quantum Information, Neurophysics, and Artificial Consciousness.
He is currently employing dynamical systems and field theory techniques to model the so-called "Neural Binding Problem". That is an open problem of great interest to Neuroscience, Artificial Intelligence, Cognitive Science, and Philosophy of Mind.
