RESEARCH INTERESTS – Mechanisms of mechanotransduction and frequency tuning in auditory hair cells

My research focuses on the physiology of hair cells isolated from the inner ear and studied with patch clamp recording and optical imaging. This research has provided descriptions of the mechanosensory transduction mechanism, the membrane channels involved in frequency tuning, and the regulatory roles of intracellular calcium. My current interest lies with the outer hair cells of the mammalian cochlea, the mechanotransducer channels and the mechanism of force generation by the stereociliary bundle that may underlie amplification and tuning of the auditory signal.
