Disorder is pervasive, resulting in random scattering of light. Can we mitigate the impact of disorder, or perhaps harness it for photonic applications? To explore these inquiries, I will present two illustrative cases. The first involves manipulating light propagation in disordered media through wavefront shaping of a laser beam. This capability allows us to, for instance, focus light through highly scattering materials or generate high-contrast patterns beyond them. In addressing the second question, I will demonstrate how multiple scattering of light can be leveraged for the optical realization of a deep neural network. This facilitates the efficient compression of vital information from optical images or videos to accelerate optical information processing.
