Major Research Interests

Our work focuses on the molecular physiology and pathology of sound encoding at the hair cell ribbon synapse. Molecular dissection and detailed physiological characterization of ribbon synapse function employ a spectrum of molecular, biophysical and physiological techniques such as mutagenesis (in collaboration with Brose), in vivo and in vitro viral gene transfer into hair cells and spiral ganglion neurons of mice, single cell RT-PCR, immunohistochemistry, confocal microscopy of hair cells, synaptic ultrastructure: STED & 4Pi microscopy; electron microscopy (in collaboration with Wichmann, Hell, Egner and Riedel), hair cell synaptic physiology: pre- or postsynaptic patch-clamp, on-cell and whole-cell membrane capacitance measurements, optical methods: Ca2+ and pHluorin imaging using confocal, epifluorescence and TIRF, mouse auditory systems physiology (recordings of otoacoustic emissions, endocochlear potential and electrocochleography and auditory brainstem responses), optogenetic stimulation of the cochlea for devising an optical cochlear implant, computational modeling (in collaboration with Wolf and Neef). We have physiologically and morphologically characterized synapses of wild-type and mutant mice with defects in hair cell synaptic coding from the molecular to the systems level. This way we have contributed to understanding hair cell ribbon synapse structure and function and initiated the concept of auditory synaptopathies
