One of the challenges in modern medicine is to develop gene and stem cell therapeutic strategies to treat deafness by targeting specific genes that play a crucial role in the generation of the disease. In all cases, it is important to understand how the auditory system normally develops and operates and how defects at molecular level lead to deafness. Moreover, understanding how the ear processes sound is essential to further technical and software development of hearing aids, including cochlear implants.
In my laboratory, we aim to identify the normal development of the mammalian auditory system and, most importantly, to determine the functional/physiological consequences of genes that when mutated cause deafness in humans.This is achieved by studying the physiological properties of the individual sensory hair cells of the mammalian cochlea using electrophysiological, calcium imaging and molecular biology techniques.
