I am a MEMS engineer with a special interest in developing biosensors for medical and biological applications. While my PhD (at EPFL, Switzerland) was on design and microfabrication of biosensing lab-on-chip devices, here at Stanford, I am focusing on integration and application of a new type of biosensors (i.e. genetically encoded fluorescent biosensors) in the cochlea. The goal of this project is to investigate an optical detecting approach for monitoring voltage changes and glutamate concentration fluctuations in the inner ear cells where there is minimal accessibility to allow us using other developed technologies such as microelectrode probes. This new technology will provide a powerful means for exploring the electrical and chemical activity patterns in the whole cochlea.
