His scientific aim is to find a unified theory of mind, brain and body through the use of synthetic methods and to apply such a theory to the development of novel technologies and quality of life enhancing applications. Paul's research group on Synthetic Perceptive, Emotive and Cognitive Systems (specs.upf.edu) comprises a multidisciplinary team of about 25 doctoral and post-doctoral researchers that include physicists, psychologists, engineers and biologists. Paul has organized SPECS along three dimensions: 1) computational models of neuronal mechanisms underlying perception, cognition, emotion and behavior, including: the cerebellum and motor learning, the hippocampus, ventral striatum and prefrontal cortex in decision making and the amygdala and cortex in emotional learning. 2) robotics and avatars as artificial bodies for neuronal models. 3) the application of the technologies developed in 2) combined with the theories from 1) to the enhancement of the quality of life.
