  • My main technical expertise is colour psychophysics and behavioural experiments.The main focus of my work has been the role of language and experience in colour perception.More broadly, I am interested in how culture and experience shape automatic assumptions to form our subjective reality.See also "About", and for recent developments and PhD opportunities, see Lab Website.

  • Is our perception and understanding of the world determined through genetically fixed and preprogramed mechanisms? Or, are they shaped through learning and experience with the physical and social environment? The answers to these questions are an integral part of our concept of human life. They will define our potential to adapt and hence which roles we can potentially play in the physical and social systems we live in. Those fundamental questions have been the centrepiece of my academic path, first when studying the role of unconscious learning in the perception of structure (MSc Psychology), then when investigating the concept of human nature in political theories (MA Politics), when delving into the role of language and experience in colour perception (PhD), and when studying sensory augmentation and substitution (postdoc in Paris). I have been intensely investigating this theme with the prime example of colour, and I am now also looking for opportunities to reach out to the worlds created by the other senses. For recent developments and PhD opportunities, see Lab Website.
