Prof. Avi Zadok received his Ph.D. in Electrical Engineering from Tel-Aviv University, Israel in 2008. In 2007-2009 he was a post-doctoral research fellow with the Department of Applied Physics of the California Institute of Technology (Caltech). He joined the Faculty of Engineering of Bar-Ilan University in 2009, and was appointed an Associate Professor in 2013. Dr. Zadok received the Krill Award of the Wolf Foundation in 2013, and a Starter Grant from the European Research Council (ERC) in 2015. He is a member of the Israel Young Academy of Science.

We like to take measurements using optical fibers. However, we run into a problem very quickly: light in standard fibers is confined to an inner core, and therefore we cannot "see" what's outside the fiber. This inherent difficulty is holding back optical fiber sensors of various chemical substances. We recently found a way around that problem. We use light to stimulate ultrasonic vibrations of the entire fiber cross-section, and to monitor these vibrations. These ultrasonic waves, in turn, are able to probe surrounding media.
