Research interests

Our research focuses on molecular and cellular mechanisms of mechanosensory transduction. We aim to discover molecules that detect mechanical stimuli and to learn how sensory signals are modulateed by synapses and transmitted to the CNS. We also work on vision and olfaction. We use a variety of advanced biophysical, electrophysiological, imaging and molecular techniques.
