Bio

I study individual differences in perception, and how these differences affect subjective experience, cognition, and interactions with our environment. I specialize in synaesthesia (mixing of the senses) and crossmodal processing. I also study the link between synaesthesia and other conditions, such as autism. I am currently developing research on other individual differences in subjective experience such as aphantasia and sensory processing sensitivity, and how these individual differences relate to differential processing and personal experiences of our environment.

Research keywords: individual differences in perception, subjective experience, synaesthesia, multisensory processing, autism, crossmodal perception, art & aesthetics, visual perception, schizophrenia, language and cognition.
