Our research focuses on developing new techniques to control the propagation of light through opaque media. The reason things look opaque (white) is because it reflects all wavelengths of light due to multiple scattering. However, when absorption is negligible, this fact gives us a chance to control light to go directly through opaque structures by actually controlling the scattered light paths. The ultimate goal of our research is to use light to noninvasively peek into thick opaque tissue for diagnosis and treatment of disease as well as for fundamental biological studies. We emphasize on interdisciplinary research that lies between physics, engineering, and biology and will venture into many different interesting paths that pop up along our journey for new discoveries.
