Andrei Faraon's research is in integrated optics. He is working on developing on-chip optical devices for bio-sensing, and neural implants for opto-genetic applications. The bio-sensing devices integrate optical networks and micro-fluidics, where optical resonators are used to monitor bio-chemical reactions in micro-fluidic chambers. The neural implants integrate optics and electronics. Optical waveguides are used to deliver light that excites or inhibits neuronal activity using opto-genetic techniques, while electrodes record action potentials at the same location.
