Major Research Interests

The perception of and the appropriate reaction to external and internal stimuli is critical for survival. In vertebrates, different chemical, mechanical and thermal stimuli are detected by specialized somatic sensory neurons (nociceptors) which transfer these signals via the spinal cord to the brain.
These neurons are equipped with a complex molecular machinery that works as detection device able to discriminate among the vast array of normal and noxious stimuli that surround us. On the front line of these molecular sensors are several ion channels which together with their protein scaffolds are responsible of the transformation of external stimuli into interpretable electrical signals reaching the brain.

Our lab employs interactomics, genetic profiling, calcium-imaging, electrophysiology, neuronal tracing and mouse behavioral studies in order to identify and characterize unknown proteins implicated in these sensory modalities in both normal and pathological conditions.
