Dr Max Garagnani

Max's research is in computational cognitive neuroscience and focuses on the implementation of biologically realistic, deep, neural-network models closely mimicking structure, connectivity, and physiology of the human cortex. These models are applied to simulate and explain the brain mechanisms underlying the natural emergence of cognitive function (the 'mind') starting from a randomly connected, uniform neural substrate, and only by means biologically realistic learning mechanisms.

While his work has been focussing mainly on language, Max's neurocomputational models have been used successfully to explain also automatic change detection and attention processes, spontaneous decisions to act (or "free will"), the emergence of memory circuits, and the recruitment of the visual cortex in blind individuals.

Teaching and Supervision

Research interests

Max Garagnani investigates the neural mechanisms underlying word learning, action planning and decision making, as well as attention, using biologically constrained computational models.
In parallel to his modelling work, he collaborates with external experimental labs to apply brain imaging techniques as a tool to test and validate the specific predictions emerging from the models.

He has been working closely and for many years with the Brain Language Lab at the Freie Universität Berlin (Germany), directed by Prof. Friedemann Pulvermüller, and was co-PI and staff member of the jointly EPSRC/BBSRC-funded interdisciplinary project BABEL, which investigated the neural mechanisms underlying embodied word learning by joint use of neuroimaging, brain-inspired modelling, neuromorphic engineering and real-time implementation on the humanoid robot iCub.

Max is currently a Lecturer in Computer Science at the Computing Department where he jointly leads the MSc in Computational Cognitive Neuroscience programme. His previous posts include Postdoctoral Researcher at the University of Plymouth, Investigator Scientist at MRC Cognition and Brain Sciences Unit (Cambridge), Visiting Researcher at the Department of Experimental Psychology (Cambridge), Visiting Scholar at the International Computer Science Institute (Berkeley, CA) and Research Fellow at the Open University (Milton Keynes).
