Here is my lab @ ULB — the Consciousness, Cognition & Computation Group.
The group’s research has always been essentially focused on elucidating the mechanisms that subtend implicit and statistical learning, but its research interests have now broadened substantially to explore the differences between conscious and unconscious processing in domains such as voluntary action and the sense of agency, decision making (including pathological gambling), visual awareness and priming, conditioning and associative learning, skill acquisition, as well as hypnosis, placebo, and suggestion. Additional research lines focus on virtual reality, emotion, cognitive development, cognitive control, and eating behaviour. Some of these research lines take place through the COOL network, which we coordinate.
A second focus is on developing and testing a novel, dynamical theory of consciousness in which learning plays a central role. From this perspective ("The Radical Plasticity" project, funded by the European Research Council), consciousness arises as a result of the brain’s continuous attempts at predicting not only the consequences of action on the world and on other agents, but also the consequences of activity in one cerebral region on activity in other regions. By this account, the brain continuously and unconsciously learns to redescribe its own activity to itself, so developing systems of metarepresentations that characterize and qualify their target representations. To get an overall feel for my perspective on the problem of consciousness, read Consciousness: The Radical Plasticity Thesis and consult this page
To explore these issues, the team combines the three main methods characteristic of contemporary cognitive neurosciences, namely behavioural, brain imaging, and computational modelling methods. CO3 has developed specific expertise in elaborating detailed neural network models of performance in various domains of cognition, and of designing and testing methods to explore the relationships between conscious and unconscious processing. The group has also recently acquired and installed a baby lab to initiate cognitive research on infants.
The lab's research is funded by different sources, including the ULB Neuroscience Institute, the F.R.S.-FNRS, BELSPO, Innoviris, the Walloon Region, the BIAL Foundation, the Canadian Institute for Advanced Research and the European Research Council. The lab is part of the Fondation ULB's research portfolio.

I teach the Philosophy of Cognitive Science (Philosophie des Sciences Cognitives, PHILB-315) class in the Faculté de Philosophie et Sciences Sociales, together with philosopher Jean-Noël Missa. This class is accessible to any master-level student from the Faculté de Philosophie et Sciences Sociales or from the Faculté des Sciences Psychologiques et de l'Education.
I have spoken in public on many different occasions and in hundreds of different places over the years, from scientific lectures delivered in stately lecture halls to interviews in television studios.
A fraction of these interventions have been recorded and are available on youtube.
The Royal Academy of Belgium also has a terrific "TV" website containing a substantial collection of audio and video recordings of lectures delivered within its stately walls. I have my own little channel there.

This application, built with the excellent Processing and featured on visual complexity.com, is a demonstration of "Interactive Activation and Competition" neural networks, as first described by J.L. McClelland in the following paper:
McClelland, J.L. (1981). Retrieving general and specific information from stored knowledge of specifics. Proceedings of the Third Annual Meeting of the Cognitive Science Society, 170-172.
A more complete description of the network is also available in:
Rumelhart, D.E., McClelland, J.L., and the PDP research group (1986).Parallel Distributed Processing Volume 1: Foundations, MIT Press.
The model was a landmark illustration of how simple networks of interconnected elements (artificial neurons, so to speak) can be organized so as to form a system that exhibits several crucial properties of human memory.

Not really. My philosophy about hobbies is embodied in this Andrew Carnegie quote:
"My heart is in the work"
I still remember the moment I first saw it engraved on the ceiling of Carnegie Mellon's Baker Hall and breaking out a sweat getting all anxious about finishing the Ph.D. I hadn't started yet. My concept of a vacation is when I am alone in my office while everybody thinks I am on vacation. In light of the above, here is another quote (from Lily Tomlin) I've grown to appreciate:
"The trouble with the rat race is that even if you win it, you're still a rat"
If you made all it the way down here you deserve to know about my collection of photographic portraits of friends and esteemed colleagues, — my ever-expanding Cabinet of Natural Philosophers. In the spirit of the Victorian-Era fashion for "Cabinets of Natural Curiosities" — elaborate private collections of wonders from the world —, this flickr set contains pictures of famous and not-so famous scientists and philosophers. Many are friends; most work on consciousness. Enjoy!
