Research Overview

We study how pain affects cognition and how cognition shapes pain perception. For example, we are interested in understanding how placebo and nocebo effects emerge, how sensory words are learned, how pain perception is modulated by social observation.

Understanding sensory perception can shed light on the neurobiology of complex cognitive processes. Unveiling the relationship between pain and cognition can be relevant for understanding not only chronic pain conditions but also psychiatric and neurological disorders, such as depression and stroke, ultimately informing diagnosis and treatment.
