which imports concepts from hyperbolic geometry and dynamic systems theory in order to explain the "weirder than weird" hallucinations one can have on this drug. Andrés describes what different levels of DMT intoxication feel like in light of a model in which experience has both variable geometric curvature and information content. The benefit of this model cashes out in a novel approach to design DMT experiences in order to maximize specific desired benefits.

He has professional experience in data science engineering, machine learning, and affective science. His research at the Qualia Research Institute ranges from algorithm design, to psychedelic theory, to neurotechnology development, to mapping and studying the computational properties of consciousness. Andrés blogs at qualiacomputing.com. The Qualia Research Institute (QRI) is a non-profit based in the Bay Area close to San Francisco which seeks to discover the computational properties of experience. QRI has a "full-stack approach" to the science of consciousness which incorporates philosophy of mind, neuroscience, and neurotechnology. For more information see: qualiaresearchinstitute.org The Harvard Science of Psychedelics Club hosts events on psychedelic research, meditation, neuroscience, students sharing their own experiences, and much more.
