Research Summary

Our laboratory uses a multidisciplinary approach to study the molecular basis of sensory physiology, with a focus on temperature- and mechano-transduction. We apply transcriptomics, electorphysiology, molecular biology and biochemistry to identify novel sensory molecules, and to understand the physiological roles and molecular properties of known temperature-, mechano-sensitive and polymodal ion channels.
