Max is a Senior Lecturer in Computer Science and co-director of the MSc in Computational Cognitive Neuroscience programme at Goldsmiths. He holds a PhD in Computational Cognitive Neuroscience from Cambridge (2009), and a PhD in Artificial Intelligence from Durham (1999).

Max's research focuses on the implementation of biologically realistic, deep, spiking 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 starting from a randomly connected, uniform neural substrate.

His previous posts include Postdoctoral Researcher at the University of Plymouth, Investigator Scientist at MRC Cognition and Brain Sciences Unit (Cambridge), Visiting Scholar at the International Computer Science Institute (Berkeley, CA) and Research Fellow at the Open University (Milton Keynes).

Teaching and Supervision

I supervise projects in my areas of interest (see "Research Interests" below).
I teach on the following programmes:

Research interests

I investigate the neural mechanisms underlying word learning, action planning and decision making, as well as attention, using biologically constrained computational models. In parallel to modelling work, I collaborate with experimental labs to apply brain imaging and behavioural methods as a tool to test and validate the predictions emerging from the models.

While my work has been focussing mainly on the brain mechanisms underlying language acquisition, the neurocomputational models I developed have been used successfully in other domains, too (for example, to explain automatic change detection and attention processes, the emergence of spontaneous decisions to act, or "free will", the formation and cortical distribution of memory cells in the neocortex, and the recruitment of the visual cortex in blind individuals -- see list of publications below).

I have 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.
